Fire on the Snow: A Quick Stewardship Update

With snow calf-deep and near zero temperatures, my forays into the parks have been a bit limited of late.

Luckily, though, our township stewardship crew, led by Dr. Ben VanderWeide, braved the cold and took another step in restoring the Wet Prairie along the Paint Creek Trail. I thought I’d take a minute to quickly share the transformation continuing in that special natural area of Oakland Township.

One of the piles of invasive vines, trees and shrubs after an hour or so of burning

I shared earlier the exciting unveiling of the original bed of Paint Creek, hidden for decades beneath invasive shrubs and vines. A dense jungle of aggressive, non-native plants had taken over the area when the creek bed was moved to accommodate the coming of the railroad in the 1870’s. The restoration work at the Wet Prairie couldn’t be done with heavy machinery because of the fragile, moist landscape of the forest. So Ben and the crew worked with chain saws and brush cutters for weeks, removing invasive plants and carefully arranging the jumble of branches, trunks and vines into tall piles. The 8-10 foot stacks were systematically located beneath holes in the tree canopy to prevent damaging mature trees.

Huge piles of cut invasive plants prepared for burning at the Wet Prairie.

In mid-February, I arrived at the scene and marveled at the site as multiple bonfires had been lit around the forest area, each on a bed of snow. It was a perfect day for controlled pile burning; the sky was blue and the wind barely moving so that the smoke would rise and disperse rather than floating away to disturb nearby residents. For a few minutes, I got close to the merry blazing of some of the fires that had been burning for an hour or so before I arrived. Their heat had definitely taken the bitter edge off a cold day in that work area. Ben told me with a laugh that a couple of crew members had provided hot dogs for lunch the day they burned at Bear Creek Nature Park and a stewardship weeny-roast ensued!

Two of the bonfires burning near the original bed of Paint Creek.

I then scrambled up the ridge overlooking the forest to see what work was left to be done, and to avoid interfering with the fire work or the safety precautions taken by the crew. In the photo below, you can see multiple stacks of wood still waiting to be lit, and one just beginning to smoke along the former path of Paint Creek. It can take a day or two for the embers of these fires to cool completely, which makes winter a great time to burn brush piles.

One stack just starting to burn and three other stacks waiting to be lit.

In the photo below, Ben and another crew member in their fire gear are just beginning to use a propane torch to set a pile ablaze. Smoke began pouring from the top as the fire crackled within the stack.

Once all the fires are completed, the next step in the restoration of this area of the Wet Prairie will take place in the spring when Ben will survey the area to see if the increased sunlight and rain reaching the forest floor have encouraged a flush of native plants. Once he knows which patches of the forest are producing native wildflowers, grasses and trees, he and the crew can carefully treat the sprouts of the invasive plants that will be trying to make a comeback.

I’ll keep you posted on this restoration project as the year moves on. Can’t wait ’til spring!

Draper Twin Lake Park: Work Begins to Restore a More Natural Landscape

Restoration north of the parking lot in the west section Draper Twin Lake Park

Ask anyone in my family if I’d ever be celebrating the felling of trees and they would look at you incredulously and start laughing. Cam? The original (occasionally literal) tree hugger?!

I had a favorite 100 year old sugar maple that befriended me as a child and I spent happy hours high in the branches with my books and snacks. When that tree and others were being felled for a housing development in the field next door, my mother – not a born nature lover – went to bat for those trees, even contacting the governor’s office since “environmental protection” was in its infancy then. But to no avail.

So imagine my astonishment at finding myself standing in the western section of Draper Twin Lake Park with Dr. Ben VanderWeide, our township’s Natural Areas Stewardship Manager, delighting in the scene pictured in this video!!

A Forestry Mower Removing Non-native Trees and Shrubs at the west section of Draper Twin Lake Park



Restoring the Habitat of the Past to Provide for a Healthy Future

The trail to Twin Lake before restoration began

My pleasure, of course, stemmed from my growing understanding and appreciation of restoration. That monster of a machine, a forestry mower, was removing a gigantic glut of non-native trees and shrubs. (See the photo above!) For decades, this natural area of grasses, wildflowers and widely spaced native trees had been farmed. The bare soil, depleted of its native diversity, suffered an invasion when farming stopped in the 1970s; trees, shrubs and other plants from Europe and Asia made the most of a great opportunity. Escaping from farms, flower gardens or landscaping, invasive plants found their way to this habitat. Benefiting from the absence of the competitors or conditions they had to contend with at home, they spread wildly. Our local plants and trees couldn’t compete. They didn’t evolve with these new arrivals and so had no defenses for countering their steady increase. It would take millennia for our native insects, birds, diseases, and plants to eventually evolve and adapt to these new plants, too long for the survival of the many species that depend on them.

That’s where our stewardship crew steps in. Ecological restoration attempts to give our local trees, grasses and wildflowers a fighting chance to thrive. When it succeeds, native plants can then provide for the whole food web that evolved with them. As you can see below, the forestry mower opened up fields and forest, beginning the process of restoring the landscape that nature designed eons ago.

The trail to Twin Lake after this fall’s restoration began

It’s not that non-native trees and shrubs are “bad”; they functional beautifully in their home environments. But they aren’t able to effectively nourish and protect the creatures that live and evolved here in Oakland Township. Butterflies may sip at non-native garden flowers, but their caterpillars generally can’t eat non-native leaves or fail to reach maturity if they do. Birds may eat non-native berries but they almost universally feed their nestlings nutritious caterpillars which are full of fat and protein. Fewer native plants means fewer caterpillars which means fewer birds, a ripple effect that then moves on through the food web. Restoring native plants to an area means lots of nature gets fed and sheltered.

Meet the Most Common (and Pesky) Invasives at Draper Twin Lake Park

Invasive shrubs lining the trail to Twin Lake before restoration this fall

So let’s get more familiar with the highly invasive shrubs and vines that ended up dominating so many of our natural areas, including Draper Twin Lake Park. For the most part, they started out in nurseries which unwittingly (or occasionally wittingly) sold them to landscapers and homeowners as decorative additions to their gardens. Some of the most infamous and tenacious invasive shrubs in our parks include Autumn Olive (Elaeagnus umbellata), Glossy Buckthorn (Frangula alnus) and Common Privet (Ligustrum vulgare), shrubs that produce plentiful fruits which unfortunately provide scant nutrition for our birds. Generally non-native fruits provide sugars (carbohydrates) for wildlife but don’t have the fats (lipids) that birds, for example, require for migration or winter survival. Research at Michigan State University has shown that birds prefer native fruits when they can get them, but will eat the less healthy non-native fruits if nothing else is available. Once eaten by birds or other animals, invasive trees and shrubs spread far and wide through their droppings.

The fruits of Oriental Bittersweet vines (Celastrus orbiculatus) are particularly pernicious. The outer yellow skins peel back to reveal red fruits, attracting both birds searching for a late season food source, and humans who unwittingly use them for decorative purposes. Birds enjoy the sugars in their fruit during late fall, but since its seeds can last a long time in the guts of birds, the plant can be spread long distances. Once established, the vine climbs quickly, reaching for light in the treetops. As the vine spirals up the trunk, it girdles and slowly strangles the tree. When the vine reaches the crown, its foliage shades out the tree’s leaves, weakening the tree. Its weight makes the tree’s crown heavy and vulnerable to toppling in high winds. It’s a real femme fatale, this vine with its pretty fruits and its deadly growth pattern.

Many invasives quickly form dense thickets in a field or woods through underground stems (rhizomes) or root suckers. Their density chokes out the sun, rain and space that our native plants require. Below is a photo from Bear Creek Nature Park that demonstrates the density that once surrounded a pine tree, killing its lower branches. And on the right at Draper Twin Lake Park, a young oak had the same problem until the restoration began this fall.

Some invasives, like Tree-of-Heaven (Ailanthus altissima), produce giant quantities of seeds which can be carried on the wind and once sown, the trees grow incredibly quickly. Growth of 3.5 to 6 feet each year of its first four years is considered normal! It also releases toxins into the soil to prevent or inhibit the growth of plants around it. In the photo on the right below, Ben placed his hand where the second year growth of one of these trees began! Faster growth means that these trees shade out neighbors and mature faster than others, allowing them to spread quickly.

You might be as surprised as I once was to learn that even some of our common and long-beloved bushes can spread invasively. That’s part of what happened at Draper Twin Lake Park. Ben found huge thickets of non-natives like Forsythia (Forsythia intermedia) from Asia and Common Lilac (Syringa vulgaris) from southeastern Europe on the western section of Draper; they both probably once surrounded the house when a farm was located here.

The Removal of Invasives Goes Beyond Mowing

Once the forestry mower has done its work, hard work lies ahead. Stumps of invasive shrubs that the mower missed are cut and carefully dabbed with herbicide to prevent re-sprouting. Some, like the persistent Tree-of-Heaven, will require further treatment and periodic mowing to discourage new growth. Oriental Bittersweet can only be removed by cutting the vines and then carefully treating the roots to prevent regrowth. New sprouts will also need to be treated repeatedly for some time, a tedious but necessary process. Some larger trees are treated by a process called “drill and fill” in which holes are drilled around the tree and herbicide is introduced. When the tree dies, it will still remain standing, storing its carbon for years to come and providing shelter for woodpeckers and other cavity nesting animals, like red squirrels or raccoons. The stewardship staff will spread native plant seed to help bring back what was choked out by the invasive trees and shrubs – native grasses first, then wildflower seed in a year or two after the invasive shrub re-sprouts have been controlled. Further down the road, prescribed fires may be used to encourage our fire-adapted native plants.

Winter Wildlife and I Explore the Newly Restored Landscape

On one of my visits to the western section of the park, Ben showed me the remains of a beaver dam and the small pond this industrious builder had created. The dam consisted of a few small trees and some plant material patched together with mud. Though we saw a few pencil-shaped stumps in the area, Ben’s guess is that when the beaver began this project a couple of years ago, it couldn’t find enough small willows or cottonwoods, its preferred building materials, to meet the beaver’s need, so it abandoned the idea. However, the beaver did create a lovely little pond behind the dam. And the little dam slowed the water down enough that Ben was surprised to find much drier footing further south in the marsh while doing a plant survey in 2020!

In the fields east of the trail, a few winter birds kept me company as they sought out frozen insect eggs or larvae in the trees newly liberated from the crush of invasive shrubs.

A small group of White-tailed Deer (Odocoileus virginianus) browsed between the newly thinned trees in the forest. Deer consume dry grasses, but unfortunately they much prefer acorns and small oak saplings in fall and winter, affecting the quality of our forests. According to a Tufts University website, in winter they also rely on insulation from stored fat and more of the coarse dark hairs in their coats called “guard hairs.” Glands in their skin produce oils that help their coats repel water, an advantage on snowy days.

One snowy morning, I spent twenty minutes or so tracking a small animal. Its prints lay in a single line, which usually indicates a fox or coyote. Wild canines, unlike domestic dogs, place their hind foot carefully into the track of the front foot on the same side, making a neat row of single, or “direct register” tracks. The tracks that I was following intrigued me because they were much smaller than most that I’d seen. After puzzling a bit, I suddenly noticed that the tracks had no nail prints at the end of the toes. And with that, I remembered that wild canines share direct register tracks with another group of animals – cats! What I’d been tracking was the small, roundish, direct register prints of a house cat! Cats, unlike canines, walk with their toenails withdrawn in order to keep them sharp for hunting – or they may have had them removed by pet owners. I shook my head, laughing at myself for tracking a cat and went back to the trail.

Squirrels and squirrel tracks were everywhere that morning! Their tracks usually appear as a block of four prints like the ones below. I think these belong to the American Red Squirrel (Tamiasciurus hudsonicus), because the larger five-toed tracks of their hind feet are slightly in front of the four-toed tracks of their front feet; that’s the pattern left when these little guys take off and land, pushing down with the front feet while swinging the hind feet forward. I also saw a larger Fox Squirrel (Sciurus niger) high up in the small branches of a tree, probably making a meal of the tiny leaf buds.

Down by the Lake, a Little Avian Hysteria

Twin Lake with perfect ovals, possibly caused by warmer water flowing upward and rotating during a thaw-freeze cycle.

Winter silence had descended when I arrived at the dock on Twin Lake one cloudy afternoon. In the deep quiet, I got intrigued by strange ovals on the lake surface. It was fun to imagine a squadron of flying saucers landing on the surface, but I was curious to do some research when I reached home. From assembling the hints I could find online, I’m guessing that they may be caused by rotating convection currents created by warm water rising and cold water falling during a frost/freeze cycle, inhibiting ice formation. But if you have better information, please let me know in the comments.

Suddenly far across the lake, a pair of Red-tailed Hawks (Buteo jamaicensis) began circling high above the trees. I caught one with my camera as it spiraled lazily. Red-tail hawks are believed to mate for life, though they quickly choose another mate if one of them dies. This pair may be nesting in the area since the Wednesday bird group saw two of them in the trees across the lake a couple of weeks later.

One of a pair of Red-tailed Hawks far above the trees across Draper Twin Lake.

Just as I spotted the hawks in the distance, a screech of alarm calls broke out from a flock of American Crows (Corvus brachyrhynchos) nearby. They flashed out of the trees in a large group, flying away to the south. Evidently, the hawks must have gone unnoticed in the forest until they rose into the air to do a little scouting together. Their appearance startled the crows who were too flustered to harass or “mob” them as they often do. My camera managed to catch one in mid-caw after it launched off a limb.

A crow cawing in sudden flight as two red-tailed hawks appear over the treetops.

After the noise subsided, I turned to look at a Muskrat lodge (Ondatra zibethicus) off the side of the dock. Muskrats may have been dozing inside since their metabolism slows way down in the winter. Or it may have left its dry sleeping chamber above the water line, swum down through its underwater entrance and begun cruising slowly along under the ice, searching for a meal. Note that unlike beavers who build their much larger lodges with trees, branches and sticks, muskrats build with mud and cattail stems or other aquatic plant material. This one was also surrounded by graceful stalks carrying the dried pom-poms of Whorled Loosestrife seed heads (Lysimachia quadrifolia). A tidy winter abode, I think.

My Evolving Understanding of “Letting Nature Takes Its Course.”

The path leading back to the parking lot after restoration began

It took me a few years of working in the parks with Ben before I fully understood the beauty and power of restoring our natural areas. I approached restoration suspiciously at first, having grown up with the ethos,”Let nature take its course.” How could altering the landscape through mowing, felling trees and shrubs, and the occasional use of herbicides be good for nature?

Remembering the Landscape of My Childhood

The first step to understanding restoration was noticing what was missing today. One day early on as a Parks volunteer in 2015, I asked Ben what birds might return if we restored the Oak Savannah landscape – grass, trees and widely spaced oaks – that had existed here before European settlement. Among other birds, he mentioned the Northern Bobwhite (Colinus virginianus). Ah! That name instantly brought back memories of the two-note song of that quail whistling from summer fields around my parents’ home on Lake George Road when I was a child. I live very near my family home now, but I haven’t heard a Bobwhite sing for more than 50 years. The native Big Bluestem grass (Andropogon gerardii) that towered over my head as a little girl was replaced by housing and short, green, non-native lawns in my teen years. As ground feeders and nesters, the Bobwhites needed that tall, stiff grass to protect them and their young from hawks and other predators and they no doubt fed off the seeds that fell from those dry stalks in the autumn. The increasing use of pesticides in farming plus habitat loss have both contributed to an 85% decline in the numbers of the Bobwhite Quail since the 1970’s. I miss them.

Listening to Doug Tallamy, author of Bringing Nature Home, at a Michigan Wildflower Conference in 2019, I was reminded of the moths that used to dance in groups around our porch light on summer nights – or splattered against the windshields of my parents’ car. I suddenly realized that I don’t see as many moths clinging to our porch windows or fluttering in the headlights now as I did years ago. The reason, I learned, was that the caterpillars of most moths and butterflies need native plants in order to feed and mature into adults; my yard, like most of my neighbors, was filled with decorative plants, shrubs and trees native to places all over the world – like Norway and Japanese Maples – but fewer of the ones more common in my childhood. Native oaks and other native trees provide sustenance for the caterpillars of many species of butterflies and moths. Here are two examples of what we may be missing: Wild Black Cherry (Prunus serotina) and Pagoda/Alternate Leaf Dogwoods are the preferred hosts for many insects including the spectacular Cecropia Moth (Hyalophora Cecropia). Oaks are especially generous, hosting the caterpillars of hundreds of species of Lepidoptera (moths and butterflies), including the impressive Polyphemus Moth (Antheraea polyphemus).

When I was a child in Oakland Township, seeing a White-tailed Deer was a rare treat. At that time, large expanses of active or abandoned farm land surrounded by woods allowed them to stay out of sight. Today development has crowded deer closer to our homes and gardens and on to our roads. The forest floor, once covered in wildflowers like trillium are more often choked with non-native shrubs or vines that take advantage of the open ground left by herds of deer browsing on the tender sprouts of wildflowers in spring or saplings in winter.

So it turns out that I was wrong. The non-native plants that fill our fields and surround our personal property were not a matter of “letting nature takes its course.” Quite the opposite, in fact. The carpets of invasive plants were the effect of humans unwittingly but actively changing our native habit over the last two hundred years.

The Good News? We Can Work to Restore What Nature Created
The trail nears the lake which now can be seen through the trees

So finally I understood that what humans had done could in some measure be undone. True, we can’t completely recreate nature’s original landscape design on any large scale or in such rich diversity. But the people of Oakland Township have made an ongoing commitment to preserving and restoring natural areas here wherever possible. Thanks to them, Ben and his crew are systematically decreasing the invasive plants in our natural areas and giving the plants that nature provided eons ago a chance to thrive again. Homeowners like us are choosing to integrate native plants and trees into our landscapes and turning turf into meadows and wildflower gardens. If enough of us create native neighborhoods, perhaps I will live to hear the whistle of the Bobwhite once more.

That’s why I, an inveterate tree lover, could celebrate the felling of invasive trees that day at Draper. What I was seeing as the forestry mower cleared away the brush was stewardship – restoring and caring for a productive, diverse ecosystem that nature took thousands of years to perfect. As the old hymn goes, I “…was blind but now I see.”

A Wet Prairie Restoration Mystery: The Case of the Missing Creek…

The Wet Prairie on the Paint Creek Trail surrounded by a tree-covered rim of soil, spoils of historical sand and gravel mining.
Text and photos by Cam Mannino

Yes, I’m returning to the Wet Prairie again even though we visited that special habitat in October. The reason is that another amazing restoration effort has been going on there since late November. It’s revealed something I’d heard about but never actually seen – the original, winding bed of Paint Creek that disappeared about 100 years ago.

A Quick Trip Back to the 1870’s

In 1871, the Detroit and Bay City Railroad Company (which later became Michigan Central Railroad) began work on a railroad line between these two cities with a flag station in the village of Goodison. This line carried both passengers and freight, including farm produce and other products back and forth from Detroit. According to former Parks Commissioner, Colleen Barkham, some time around 1920, a local entrepreneur, Mr. Frier, bought the land that is now the Wet Prairie and other areas along the tracks and began mining sand to ship to industries in the big city.

1963 aerial image with the old route of Paint Creek (blue) and one of the rail spurs for sand and gravel mining (yellow) highlighted. The current restoration area is outlined in red. The core wet prairie habitat is labeled in green text. Image a screenshot from the Oakland County Property Gateway (https://gis.oakgov.com/PropertyGateway/Home.mvc).

He called his company Goodison Sand and Gravel, and what made shipping sand feasible then was the handy availability of the train. Colleen, co-chair of the Oakland Township Historical Society, generously shared a photo of the operation from the Society’s archives.

You can see how it worked – the sand coming down the chute from the land above right onto a freight car on the railroad line! Now I had an answer to the first part of the Wet Prairie mystery: Why is the Wet Prairie encircled by a rim of treed hummocks? (See the top photo in the blog.) Apparently, the land in the center of the current Wet Prairie was skimmed off to get at the sand, leaving a bulging rim of soil around the site. Wow. Quite a dramatic change of habitat, eh? Perhaps that explains why the mineral-rich water table that feeds the Wet Prairie’s unusual autumn flowers is so near the surface. The soil above the water table was removed about a hundred years ago!

An Earlier Dramatic Change in the 1870’s

Paint Creek’s current stream bed along the Paint Creek Trail

But there’s more! Back in the late 1800’s, when the railroad track was being laid, a problem arose with Paint Creek which looped and switch-backed across this section of the railroad’s property. No problem, said the engineers of the time; we’ll just move the creek! And that’s exactly what they did. That’s why today Paint Creek runs in a such a neat straight line along big sections of the trail. The narrow bed created for the creek has probably deepened over the years, since the creek now has only a small flood plain to stretch out in after heavy rains or snow melt. So 50 years or so after the railroad’s decision to move Paint Creek, Goodison Sand and Gravel reaped the benefit from an easy means of transporting their sand by rail.

So, where did Paint Creek run before it was moved?

When I learned of the changed path of Paint Creek several years ago, it occurred to me to wonder what happened to the old bed of Paint Creek. Our stewardship manager, Dr. Ben VanderWeide, knew the answer but couldn’t show me; the original stream bed was buried in a monumental tangle of invasive shrubs and vines. But no longer. Ben and his stewardship crew has taken on the task this fall and winter of removing the invasive undergrowth that covered the forest floor where Paint Creek once meandered across a moist forest of Bur Oaks (Quercus macrocarpa). Let me show you the miracle that the crew is performing just north of the Wet Prairie.

Since the 1920’s when the sand was hauled away, the native wildflowers that bloomed on the Wet Prairie had been bathed in sunlight. But over the years, trees began to spread from the forest, providing too much shade for sun-loving species. So restoration required removing some trees that encroached on the Wet Prairie’s sunny expanse. This fall, the stewardship team began an ambitious and arduous effort to clear away that thick layer of aggressive and invasive shrubs beneath the canopy in the woods north of the Wet Prairie. Here’s the type of wild tangles that confronted them – a jungle of privet, common buckthorn, glossy buckthorn, autumn olive, multiflora rose, and oriental bittersweet.

The dense tangle of shrubs and vines that covered the area north of the Wet Prairie and along the Paint Creek Trail

And look what they accomplished just along the edge of the trail!

The area north of the Wet Prairie near the Paint Creek trail cleared of invasive underbrush after restoration began.

What follows that effort is now weeks of hard slogging to remove invasive shrubs deeper into the woods. Because of the moist soil in the woods, small trees, shrubs and vines must be removed without large machinery and then piled carefully into high stacks in clear areas where they can be burned late this winter when the woody material has dried.

A pile of invasive shrubs and vines cut and stacked in preparation for burning .

That work has already begun to unveil the original wandering path of Paint Creek. In December, I finally got a chance to see where the creek once ran. The crew has spent weeks clearing the banks of the former stream bed. Water fills its ancient path through the woods, but not running water. Rising ground water, snow melt and rainfall settle in the old bed, so it’s clear where the creek used to flow.

A section of the original path of Paint Creek winding through the forest

What an amazing sight! I was looking at the remains of the path nature chose for Paint Creek until about 150 years ago! Since the photo above was taken on December 23, a huge amount of work before and after the holiday break made impressive progress. Look below at the piles of vines and shrubs removed and stacked as of Friday, January 8.

Piles of invasive plants will be burned once the woody material dries

A lot of work remains to be done to restore this special, fragile space – more cutting and removal. As shrubs are removed, the crew carefully dabs each trunk with a stained herbicide to prevent it from re-sprouting.

Stumps of invasive shrubs are dabbed with a sponge containing a stained treatment which will keep them from re-sprouting.

Then Ben will wait to see which native plants emerge after the removal of the invasive shrubs that have smothered them for all these years, benefiting now from more sun, more rain or simply more space to grow and propagate. Ben tells me that while pulling garlic mustard in the spring, he saw a large patch of delicate Starry False Solomon Seal (Maianthemum stellatum) beyond the area currently cleared, some Yellow Lady Slippers (Cypripedium parviflorum) and huge spreads of Skunk Cabbage (Symplocarpus foetidus) in the wet areas. I hope I’ll be able to visit here with him in the spring or summer to see what else bursts forth after the restoration!

Ben showed me an old tip-up where a huge two-trunked Bur Oak had fallen in two directions – one into the forest and the other across the old creek bed, making a bridge of sorts to an island once surrounded by flowing water in the original Paint Creek channel. The tip-up left a deep hole where the roots were ripped out. Ben tells me that tip-ups can create two habitats – a watery one in the hole below, and a green one above with mosses, ferns, grasses or shrubs eventually growing over the root ball. He’s seen forested wetlands in which tree trunks had decomposed completely, leaving only a hollow in the earth beneath a mossy hillock to indicate the presence of an ancient tip-up.

In early winter the only green I could spot in this woods were stretches of Scouring Rush (Equisetum hyemale), a kind of horsetail with enough silica in it to make it useful long ago as a scrubbing tool. The bright orange disk of a crustose lichen (a composite organism of algae and fungi) caught my eye in winter’s gray light as well as a log sporting a nice collection of Turkey Tail mushrooms (Trametes versicolor). Ben pointed out the fertile fronds of Ostrich Ferns (Matteuccia struthiopteris) which carry the spores which may germinate to grow new ostrich ferns.

Ben also introduced me to the largest Eastern Cottonwood (Populus deltoides) that I’ve ever seen. Cottonwoods can be aggressive trees, spreading like crazy with multiple seeds attached to cottony strands. So they’re not always welcome in areas where Ben is trying to restore an area’s natural diversity. This tree though was impressive. According to Wikipedia, cottonwoods grow quickly to 65 -195 feet, but in most habitats live only 70-100 years, not long in the world of trees. Ben can’t help admiring this one, so it will be left to prosper. Here’s my husband Reg standing next to it to give you a sense of its girth and height.

A Janus Moment: Imagining the Past and the Future at the Same Time

A section of Paint Creek’s former stream bed

Janus is the Roman god after which January is thought to have been named. He is usually depicted with a double face looking back to the past and forward to the future. How appropriate, then, that this January, during a transitional time at the Wet Prairie, I was lucky enough to imitate him. Standing at the edge of Paint Creek’s original stream bed, camera in hand, I happily immersed myself in imagining the past: the glint of the water wending its way through some large, widely dispersed Bur Oaks with wetland flowers and ancient sedges painting the dappled shade with color. I could picture native Brook Trout (Salvelinus fontinalis), their stippled scales flashing, as they navigated their slender bodies around the island in the creek. Iridescent Ebony Jewelwing damsel flies (Calopteryx maculata) may have darted above the surface, delicately landing like dancers on surrounding greenery. I wondered about the indigenous people who may have picked their muddy way among these trees and what they might have noticed and enjoyed along the creek.

Today as the stewardship crew gradually clears away the smothering snarl of invasive shrubs, it feels to me as if the oaks and the huge cottonwood can breathe more easily, bathed in more sun and rain. I let my thoughts turn to the spring, when the Lady Slippers and that patch of Starry Solomon Seal bloom again unhindered by overhanging vines and shrubs. And I can’t help hoping that seeds that have waited for decades will wake in the warming earth once more and begin their cycle of growth. Today Paint Creek may be bustling its way beyond the busy trail to the east, but its ancient bed will still gather water from the sky and earth when it can. Moistening its surroundings, it will now have a chance to once again nurture the diverse community of native plants that shared its habitat for centuries. What a gift that will be to all the native grasses, sedges, wildflowers and wildlife – and us as well! And what a pleasure to have the “Mystery of the Missing Creek” solved during this ambitious restoration project.

A Short Excursion into the Rich Diversity of Blue Heron Environmental Area

Blue Heron Environmental Area on Rochester Road is a place I’ve rarely visited. This special natural area was  purchased years ago by our Parks and Recreation Commission to protect a Great Blue Heron rookery that has since moved on.  The township has begun planning for the area’s future use, but for now it’s preserved as a beautiful green space with a large arc of wetland curving through a high-quality lowland forest. The fields outside the forest are planted by a local farmer which helps prevent the spread of invasive shrubs until future plans come to fruition.

Until recently, I had only been in this forest to pull garlic mustard during spring volunteer workdays. But in early June, I was able to join our township Stewardship Manager Dr. Ben VanderWeide and his stewardship specialist, Grant VanderLaan, for a short exploration while they there were clearing invasive plants. What a great opportunity to share some of the special flowers, vivid dragonflies, and elder trees that inhabit this moist, shady world!

Escorted Along the Fields by a Fleet of Dragonflies!

While skirting the farm field near Rochester Road, I noticed a sunlit meadow to my right that was splashed with blossoms of native Daisy Fleabane (Erigeron annuus).

The sturdy, daisy-like faces of native Daisy Fleabane dotted a restored field at Blue Heron.

All along the field edges, dragonflies were patrolling, and occasionally dueling over, their territories. Blue Heron Environmental Area is ideal for these aerial wizards. In the open areas, they can scoop up mosquitoes, flies, midges or even moths and damselflies out of the air, while attracting a mate with their speed and skill. And once they do mate, the forest wetlands provide an ideal spot for depositing their eggs. Since walking humans stir up a lot of insects, they were also happy to accompany me along the field edge to harvest whatever I stirred out of the grass.

The Widow Skimmer female below (Libellula luctuosa) looks very like the male, except that her abdomen is black and gold while his is gray-blue. The male also has white patches beyond the dark brown ones on each wing. Widow Skimmers find shelter at night by hanging underneath overhanging leaves.

Widow skimmer female or juvenile 2 BHEA

The offspring of this  female Widow Skimmer (Libellula luctuosa) will resemble her closely, but with male juveniles,  the gold stripe on its abdomen will gradually fade to gray-blue.

Eastern Pondhawks (Erythemis simplicicollis) are fierce predators. They have long spines on their legs for grasping prey, which includes any insect their size or smaller – occasionally even other Eastern Pondhawks! These dragonflies are more likely than others to follow along as you walk in order to feast on swarms of insects. Eastern Pondhawks are “dimorphic,” meaning the male and female look very different as you can see below.

During maturation, this male Eastern Pondhawk’s abdomen slowly turned to blue-gray starting at the tip of his abdomen and ending at his thorax. This guy looks ready to take me on!

According to Dragonflies of the North Woods by Kurt Mead, female Eastern Pondhawks can mate multiple times in a day. Perhaps the female’s bright green color and striped abdomen, so different from the male’s, makes her more visible to possible suitors.

A female Eastern Pondhawk can lay up 2100 eggs per day. She releases them into the water by dipping her abdomen into the water in short intervals.

The Twelve-spotted Skimmer (Libellula pulchella) is a favorite of mine not only because of the alternating stripes on its wings, but because of the way it hunts. It sallies forth from a perch to snag its prey, and then frequently returns to the same perch repeatedly – giving amateurs like me multiple chances for a decent photo! All dragonflies are a challenge to photograph in flight, but particularly Twelve-spotteds since they fly in bursts of speed and can reverse direction in a flash.

The male Twelve-spotted Skimmer sometimes hovers over the female during egg-laying to prevent other males from harassing or mating with her.

The Common Whitetail (Plathemis lydia) below could be a female, but is more likely a juvenile, since they’re the ones that tend to head for fields and open areas, leaving the water behind once they emerge from their larval stage. Their appearance is not only identical to the adult female; it also closely resembles the female Twelve-spotted Skimmer. The only difference is that the yellowish-white stripes of the female/juvenile Whitetail form a jagged line down the sides of the abdomen (see below), while the side stripes of the female Twelve-spotted form a neat straight line. So needless to say, I always need a photo to decide which one I saw when a female of either species appears.

A juvenile Common Whitetail is more likely to be found at a field edge than the adult female, though both look exactly alike during early maturation.

I came across two other interesting insects at the edge of the fields. Noticing delicate movement at my feet, I finally spotted a strange creature that is completely harmless to us humans, but quite a predator! A Hangingfly (genus Bittacus) does just as its name implies; it dangles beneath leaves by its looong front legs which have claspers to grasp leaves or stems for support. It uses its other four legs to snag any unwary insect passersby. It looks a bit like a Crane Fly but isn’t related.

A Hangingfly hopes to snag unsuspecting insects as it dangles from under a leaf.

And a Six-spotted Tiger Beetle (Cicindela sexguttata) showed up right where they always are – in a bright spot at the edge of a field or forest, its stiff, iridescent green wings shining in the sunlight.

A Six-spotted Tiger Beetle paused in a sunlit spot on an old log at the edge of a field.

Something New:  Restoring a Forest

A field now cleared of invasive shrubs that will eventually be restored to the forest it once was.

Have a look at the photo of the cleared, green field above.  Until two years ago, it was choked with Autumn Olive and Glossy Buckthorn, invasive non-native shrubs that quickly take over abandoned farm fields. A forestry mower took them down in the winter and the area was soon sown with native grasses and wildflowers. The stewardship summer crew treated the invasive shrub regrowth the following summer.

Often stewardship work in our township begins with this clearing process as the first step in turning a field back into a native prairie or savanna- but not so at Blue Heron.  When I visited, Ben showed me that the cleared field in the photo had originally been part of an earlier forest.

As you enter the woods, you can see a demarcation where younger, smaller trees give way to taller, thicker, older ones.  It’s likely that decades ago, the older trees,  many of which lean eastward,  had been reaching for sun at the edge of a farmed field . The bigger trees to the right in the photo probably grew back after the forest was originally cleared for farming in the 19th century. The smaller trees to the left probably sprouted after part of the field was no longer farmed in the second half of the twentieth century.

Older, larger trees on. the right were once leaning into the sun at the edge of the field when it was farmed years ago. Smaller trees beyond started growing when part of the farm field was abandoned many years later.

Stewardship plans include eventually planting native oaks in the open, cleared meadow  in order to restore more of the native trees that thrived here before farming began. I’d love to be around to see the restoration of a forest!

The Rich Diversity of a Lowland Forest

Blue Heron Environmental Area is a high-quality lowland forest with a curving arc of wetlands.

I’ve only explored a small section of the current woods at Blue Heron Environmental Area, but I’m already wowed. In the sources I used to research the plants I saw here, I  came across phrases like, “found only in high-quality wetlands,” or “found in high quality woodlands.” Because much of the forest has been undisturbed for a long time, Blue Heron provides high-quality examples of both.

Moist Forest Flora – and Some Rare Beauties!

As I stepped with Ben into the older forest, the shade deepened. Ben kindly took me to see a unique orchid. It seems that at one time, this natural area hosted two kinds of Ladyslippers. The more common, and still lovely Small-flowered Yellow Ladyslipper (Cypripedium parviflorum var. makasin) peeks out of the greenery beneath the tall trees. I love how the dark sepals form the purplish ribbons of the lady’s slipper.

The sepals of the Small-flowered Yellow Ladyslipper that once enclosed its bud look like the ribbons that wound around a lady’s leg to secure her shoe in ages past.

But there was once another orchid here which Ben and Grant haven’t yet spotted, the  rarer White Ladyslipper (Cypripedium candidum)Here’s a photo of one from iNaturalist.org taken by photographer Erin Faulkner. Note that the sepal “ribbons” are green with faint flecks of purple rather than the dark purple and bright yellow sepals of the Yellow Ladyslipper above.

Ben thinks the rare White Ladyslipper must have cross-pollinated with the Yellow Ladyslipper to create a hybrid at Blue Heron. Photo by Erin Faulkner (CC BY-NC)

Ben presumes that White Ladyslippers once grew in this natural area because here and there today grows a hybrid between these two native orchids. The hybrid wildflower at Blue Heron has the white “slipper” of the White Ladyslipper but the purple, sepal “ribbons” of the Yellow Ladyslipper. The two native Ladyslippers must have cross-pollinated and produced this special hybrid that Grant found. I’m so glad that I got to see several of them and am able to share one with you!

The hybrid Ladyslipper at Blue Heron has the white “slipper” of the White Ladyslipper and purple sepal “ribbons” of the Yellow Ladyslipper.

Also enjoying the beautiful forest floor, I noticed little yellow pom-poms on a stem growing in the mottled shade of a long, arcing marsh. Ben identified it as Tufted Loosestrife (Lysimachia thrysiflora), a species of Loosestrife I’d never seen before. Its clusters of tiny blossoms, called “racemes,” emerge from the middle axils of the long, graceful leaves like tiny fireworks. It’s described by a useful wildflower website, Illinois Wildflowers, as “found in higher quality wetlands.”

The yellow racemes (clusters of separate flowers) of Tufted Loosestrife catch the light and shine in the shade at the marsh’s edge.

Large areas near the marsh were carpeted with a calf-high plant I’d never before noticed on my hikes –  Richweed (Collinsonia canadensis). This member of the mint family produces a plume or spike of tiny yellow flowers in mid-summer, adding a spark of color to the dense shade when little else is in flower. Since I saw only its leaves, here’s a photo of the plant blooming by inaturalist photographer Sirruba.

Ferns Waving from the Forest Floor

The feathery fronds of a glorious variety of ferns sway above the ground near the marsh at Blue Heron Environmental Area. Ben  identified two for me and I spotted an old favorite as well. The Maidenhair Fern (Adiantum pedatum) is described by Illinois Wildflowers as “found in higher quality woodlands where the original ground flora is largely intact.” I saw its fan-shaped fronds spiraling out of the ground quite near the center of the marsh’s arc. It carries its spores in narrow bands on the underside of the leaflets near the tip. Each leaflet on the frond folds down slightly to partially cover the sporangia, the structures that carry the spores. They will eventually break open and release the spores to the wind.

Maidenhair Fern enjoys the humid shade of Blue Heron.

The Royal Fern (Osmunda regalis) produces a glorious, rising plume of infertile fronds that catch the sunlight and feed the plant through photosynthesis. The shorter, straight fertile fronds are thinner and produce yellow bead-like spores. The draining of wetlands around the world has had a big impact on Royal Ferns, so I’m happy to have seen so many here!

A Royal Fern near the marsh rises like a large, green bouquet rising from the moist forest floor.

All over the woodland grows an old friend, the Sensitive Fern, reportedly so-named because its fertile fronds wither at the first frost and arrive after the last frost. Its green, infertile fronds with their jagged edges feed the roots while the smaller fertile fronds eventually produce shiny, brown, bead-like sporangia that last through the winter before breaking open to release the spores. Sensitive ferns also reproduce by underground stems called rhizomes.

Wet Woods Extras

High Bush Blueberry (Vaccinium corymbosum), an unusual native plant that I’ve only seen before at Cranberry Lake Park, huddled under the shade of a willow on a hummock in  the marsh. When I got closer with my camera, I could see fruit just beginning to form. Native mining bees and bumblebees or non-native honeybees must have found the little white nodding blossoms and pollinated them as they foraged. Some lucky bird or mammal has a treat coming!

The petals of Highbush Blueberry blossoms have dropped and the fruit is forming.

Near the Blueberry bush, in a wet crevice of a moss-covered hummock, I spotted a tiny Wood Frog (Lithobates sylvaticus).  It must have hatched this spring from eggs quickly laid in a vernal pool back in March. Less than 2 inches long, it floated in the shallow water or rested on the moist mud as it explored its shady grotto.

Healthy Little Saplings, a Majestic Beech and Some Colorful “Hangers On”

Among the mixture of maples and oaks, some trees that I see less often have also found a suitable habitat in the forest at Blue Heron. Ben told me of a large Tulip Tree (Liriodendron tulipifera) farther back in the woods that I’d missed. But I did see this little sapling of one springing up from the moist earth. I love how tiny saplings create such large leaves to capture as much sunlight as possible. Let’s hope it escapes the attention of foraging deer!

A tiny Tulip Tree will have to survive foraging deer to reach its adult size.

I did find an impressive American Beech (Fagus grandifolia) reaching up to the sunlight with its smooth, gray bark. Wildlife love the plentiful beechnuts that this tree will send rattling to the earth. And according to the Trees of Michigan Field Guide by Stan Tekiela, the seedlings and saplings that manage to take root can survive in the shade for years waiting for other trees to fall, giving them the sunlight and space they need. I’m hoping for a grove of Beeches – a new favorite of mine.

A huge American Beech made its way up into the sunlight in the forest at Blue Heron.

A tiny Swamp Oak (Quercus bicolor) must have begun its upward journey from the forest floor when the acorns dropped last fall. Swamp Oak acorns usually come in pairs and sprout shortly after falling, according to Stan Tekiela. If one survives hungry birds and animals, it grows more quickly than most oaks. And it could live for up to 300 years,  according to Wikipedia. Good luck, little oak!

Leaves of Swamp Oaks are dark green above and lighter below – hence its species name, “bicolor.”

What first appeared to be some sort of fungus had sprung up around a large fallen oak in the woods.  But it wasn’t a fungus; it was a parasitic plant commonly called Cancer Root or Bear Corn (Conopholis americana). It’s an underground plant that consequently can’t photosynthesize sunlight. Instead it feeds off the roots of woody plants, especially oaks and beeches. This interesting pinecone shape is the flowering stem of the underground plant which grows on the roots about four years before producing these flowers that can grow as high as 8 inches. I’m continually amazed by the variety of ways that nature has found to sustain life.

Cancer root or Bear corn draws its sustenance from the roots of trees since the plant is underground and can’t photosynthesize. These are its flowers.

Imagining Blue Heron’s Past, Protecting It Today and Restoring It For the Future

A section of the long crescent of marsh at Blue Heron Environmental Area.

The distant past of this striking lowland forest can only be imagined. Before farming began here in the 1800’s, an old growth forest probably stretched out from its present site across where Rochester Road is now and beyond. Gray wolves probably roamed the area, keeping a healthy deer population in check. Those White Ladyslippers may have bloomed in profusion in an open wet meadow pocket, since non-native plants had not yet been introduced to the ecosystem.

Today Blue Heron is a special natural area preserved by the Parks and Recreation Commission and the residents who support our parks. The old growth forest is gone, but large trees from the 19th century still stand tall among the wetlands shading a forest floor full of native plants. Thanks to our stewardship program, garlic mustard and other invasive trees, flowers and shrubs – some brought early on by European settlers, others unwittingly planted in our gardens or along our streets – are being removed from our parks and controlled in a variety of ways,  including prescribed burns. As a result, our heritage of native plants can begin to reassert itself, providing a healthier, more productive habitat for native wildlife.

And for those of us who want to pass that heritage on to future generations, we can dream of young children wandering among tall oaks and waving native grasses that were restored to Blue Heron Environmental Area by people in our time who valued the gifts of the natural world. What a legacy, eh?

Worried About the Planet? Let’s Make a Difference One Garden at a Time.

It’s admittedly a worrisome time for those of us  who love our small, blue planet. Devastating fires, raging floods, 30 billion fewer birds in the last 50 years, a UN report that 100 million species of plants and animals are at risk of extinction within decades. According to Eduardo Brondizio at Indiana University, half a million species have “insufficient habitat for long-term survival.” Their best hope is restoration of their habitat.

Aha! Now here’s something you and I can do something about! And we can do it without leaving home, or participating in protests or influencing recalcitrant politicians. We can enrich the habitat right beyond our kitchen windows. And it won’t take sacrifice – in fact, it’s rewarding! It won’t take giant sums of money or raising taxes. All it takes, dear kindred spirits, is adding native plants to our gardens and yards – as many as we can plant each year. By doing so, we can make a HUGE difference to the survival of species. Stick with me here. The news keeps getting more hopeful as we move along.

Is Your Yard Full of Non-native Plants?  Mine Is…

I’m betting your garden is a lot like mine – filled with non-native trees, grass, shrubs and flowers that evolved in distant countries.  I’m thinking of common garden plants like Lilacs (Syringa vulgaris) from the Balkans in Southeastern Europe, Forsythia (Forsythia intermedia) from eastern Asia,  or Vinca (Vinca minor) from Europe, Africa and Asia.  Take a short world tour in this slideshow and discover where a few of our most popular garden plants originated. [Use pause button for time to read captions.)

This slideshow requires JavaScript.

Our non-native, international gardens look lovely;  butterflies sip nectar from the flowers and insects never leave a hole in the leaves.  The turf grass looks like a seamless green carpet if we fertilize it and water it regularly.  So what’s the problem?

Well, in their homelands, our non-native plants were not a problem.  They did just what nature asks plant to do – pass on  the sun’s energy (through photosynthesis) to all the other organisms in their habitat that can’t do that.  In its native Europe, invasive Phragmites (Phragmites australis subspecies australis), for example,  supports over 170 insect species. But not here! Here the invasive, non-native grass crowding every wet roadside supports only 5 species – and it’s been here for centuries!

Burning won’t kill phragmites! Here, we’re using controlled burning to remove dead Phragmites that was treated in fall 2014. We remove dead material in the hope that native plants may emerge.

Problem: Our Gardens are Missing One Essential Feature – Plentiful Caterpillars

Now you may be thinking, “Caterpillars eat holes in leaves! The lack of caterpillars is not a problem!!!” Well, actually, it is. Like me, you’ve probably always thought of your garden or lawn as an artistic or decorative enterprise. And it should be! We all need beauty around us. But nature needs our garden flowers, grasses, shrubs and trees to be productive, as well as beautiful. Our yards also need to nourish creatures large and small who live around us. The sad truth is that  most of our gardens are green, colorful food deserts that leave nature hungry and malnourished. Luckily, we can easily change that!

Insects: “The Little Things that Run the World”

Insects, including butterflies, moths, and many other pollinators keep an ecosystem fed. They really are, as the famous biologist E.O. Wilson said, “the little things that run the world.” An insect’s chubby caterpillars chewing and hunching along a plant stem provide essential food for the whole web of life. Birds stuff them down the scrawny throats of baby birds; caterpillars are soft and filled with the fat and protein nestlings need. Adult birds snag insects from the air, pluck them off the ground, and snatch them from leaves. They even spend winter days probing loose bark looking for frozen insect eggs or caterpillars to get the protein that helps keep their small bodies warm on icy nights.

Without enough caterpillars, birds won’t lay a full clutch of eggs in the spring. Their  young will not be as large and healthy. And they need a lot of them! Chickadees, for example, need 6,000 to 9,000 caterpillars to raise their clutch of nestlings! Caterpillars are simply the most important food source for birds, amphibians, reptiles, fish, and some mammals. Seeds and fruits contribute to food webs too – but caterpillars are essential.

So Why Are Our Yards Missing So Many Caterpillars?

Ninety percent of our native caterpillars, the young of daytime butterflies and the moths who maneuver through the night, are picky eaters! They can only eat plants with which they co-evolved. They are specialists who, over eons, have overcome the chemical defenses of particular native plants and are now adapted to eat them and nothing else. Unfortunately, they aren’t able to switch to what’s available. It would take thousands of years of evolution to make that possible. So if our caterpillars don’t hatch out on a native plant, they generally die of malnutrition before reaching adulthood.

The Monarch butterfly (Danaus plexippus), of course, is the classic example; its caterpillars can eat only one genus – the milkweeds (genus Asclepias).  Monarchs will sip nectar from all kinds of flowers, but their caterpillars need one of the milkweed species for food that will nourish them to adulthood. And 90% of all our insects face the same challenge of finding the native plants their young can eat. Not enough native plants means not enough insects and their caterpillars, which means not enough birds, not enough amphibians –  and on it goes as hunger spreads through a habitat’s food web.

A Beautiful, Simple Solution: Plant More Native Flowers, Grasses, Shrubs and Trees

So many environmental issues are beyond our control. But we can control our yards, our gardens, the fields and woods on our land. And we can turn around the declining numbers of butterflies, pollinators, birds and more by nourishing wildlife around us with beautiful native plants. They come in all kinds of colors and shapes. Some thrive in wet areas, some in dry. Some need the sunshine, some the shade. Some bloom in only one season, some in more than one. Some are even green all winter! Here’s just a tiny, rainbow sampling  to whet your appetite!

Our Gardens and Yards Can Change Gradually, Right?

We don’t need to overhaul our gardens overnight. I plan to just gradually add in more native plants each year. Ideally, our goal is to reach at least 70% native – but any increase in native plants benefits our local habitats. For example, I can’t afford to eliminate the non-native woods of invasive Black Locust (Robinia pseudoacacia) next to our driveway – but I can remove its invasive sprouts wherever I come across one. And maybe year by year, we can remove a bit more of the Vinca and Lily-of -the-Valley that have choked out native woodland flowers on the forest floor. I’m thinking  of removing Locusts that are crowding the few native Wild Black Cherry Trees (Prunus serotina) in the woods and perhaps adding in a few native understory trees to help out the birds and insects.

Dense woods of non-native Black Locust

Three years ago, I started taking on the invasive Garlic Mustard (Alliaria petiolata) that has encircled our yard and infiltrated the woods for years. Pulling them out by the roots is quite easy; my 4-year-old neighbor enjoyed doing it with me! And the reward at our house is that beautiful, native White Snakeroot (Ageratina altissima) now rises out of the earth each autumn wherever I pulled the Garlic Mustard in the spring! (Have a look at the beautiful bank of white blossoms below!) I’m anxious to know what else may be hiding in the seed bank under the forest floor!

If placed in the right environment, native plants are less fussy than non-native plants we usually get from the garden store. They’ve evolved in our ecosystem so they don’t need the regular watering, fertilizing or soil amendments that non-natives usually do. In fact many of our native plants do better in poor soil! Rain generally provides enough water for them, except in severe droughts. You’ll need to experiment to see what works, just as you do with non-native plants. Some will grow more vigorously than you’d like and need to be thinned; consider sharing them with neighbors! Others will need to be moved to a new location. That’s OK! It’s all a learning process, right?

A Word about that Lawn…

Douglas W. Tallamy, author of Bringing Nature Home, a sort of  “bible” for native gardeners, points out that millions of acres in America are covered by our lawns. In fact researchers say that the American lawn covers an area the size of New England! Turf grasses are non-native and require huge amounts of water, chemical fertilizers and herbicides to keep them  green. Mowing them frequently also uses lots of fossil fuel.

Now neither Doug Tallamy nor I are not advocating that you ignore your lawn and let it grow into a fallow field full of invasive plants! What Tallamy and other conservationists are asking is this: Could you do with less grass and plant more native gardens? Could you plant a native White Oak (Quercus alba) in your front yard? (White Oaks can support over 500 different insect species and still look great! Could you put native shrubs along your driveway? Maybe you could plant a more formal native garden in the front with drifts or masses of native plants that love to be planted close together.  (No need for mulch!)

Grass paths could be used to guide you through your landscape; turf grass is great to walk on. If your children play outside (and I fervently hope they do!), leave a play area but surround it with native wildflowers or flowering native shrubs. And where you have slopes or large open areas with plenty of sun, consider taller native grasses like Little Bluestem (Schizachyrium scoparium) or Big Bluestem (Andropogon gerardi) and a variety of sun-loving prairie plants. Native grasses and shrubs provide artistic structure in a garden, but also give caterpillars safe places to spin their chrysalises and cocoons.  The possibilities are endless.

An Inspiration for the Future:  The “Homegrown National Park”

In his newest book,  Nature’s Best Hope, Dr. Tallamy proposes a glorious vision of what a dedicated nation could create for its people and its wildlife. He envisions all of us together creating huge swaths of native habitat by linking our native-growing neighborhoods into a “Homegrown National Park.” Imagine that! Our new national park could be as large as 20 million acres if we all reduced our lawn areas by half. Wow! An audacious idea, but theoretically possible. For the moment though, our goal can simply be to enhance the habitat around our own houses and perhaps eventually a network of houses and neighborhoods full of both life and beauty.

Imagine Your Native Garden as Living Landscape, a Beautiful Habitat Where Nature Thrives

February is a great time for garden dreaming. Envision the possibilities outside your kitchen window. A green path wends it way between native gardens that change with each season. Warm patches of sunlight bring butterflies looking for nectar. Perhaps fledgling bluebirds beg to be fed beneath your native flowering shrub. In the shade of the native tree canopy, migrating birds stop by to sing while looking for caterpillars or to pluck a few berries on their way south for the winter. I’m finding a whole new set of yard dreams myself. I hope you conjure up a few too, and add some natives to your yard this year.
