Spring is an incredibly busy time for our stewardship manager, Dr. Ben VanderWeide. So many projects demand attention at once – and they all depend on so many variables! Planting native seed has to happen while the ground is still cold and wet. Prescribed burns, however, have to happen when the wind is low and from the right direction, and the plants are dry.
Meanwhile volunteer training and supervision is going on for vernal pool monitoring, nesting box monitoring and burn crews. Whew! Here’s a sample of what went on in late March and April at just one location – Bear Creek Nature Park.
Seeding Mowed Areas with Native Seed
In late March, Dr. Ben and Stewardship Specialist Alyssa Radzwion began a project to spread the seeds of native grasses and wildflowers in the areas cleared by forestry mowing last fall. The hope is that these native plants can help prevent some renewed growth of the invasive shrubs that were removed. It’s a project that will take years of persistent work, but they made a good beginning.
Monitoring the Life in Vernal Pools
In mid- April, the stewardship staff, a stewardship tech from the Six Rivers Land Conservancy (see Ian below) and a group of volunteers, including Parks Commissioner Dan Simon and his wife pulled on tall boots and waders and ventured into the vernal pools in Bear Creek’s forest. The purpose is to monitor the health of these temporary pools, which are biodiversity hotspots in our forests.
As usual, the crew found a surprising variety of creatures. Spring frogs, salamanders and many insects choose vernal pools as a good place to mate and lay eggs because they are free of hungry fish. The pools dry up and disappear in warmer weather, preventing fish from establishing if they are introduced.
Nest Box Monitoring
For the second year, Dr. Ben has organized and trained a group of volunteers to monitor nest boxes from first nesting to the flight of fledglings. We “citizen scientists” report our data to Cornell Ornithology Lab’s “NestWatch” program. This year Ben added six boxes in Bear Creek Nature Park to the ones in Draper Twin Lake Park, Charles Ilsley Park, and along the Paint Creek Trail. And I’ll be the Bear Creek monitor this year, which will be great! I’m hoping to count Eastern Bluebirds and Tree Swallows, and possibly Black-capped Chickadees or House Wrens where the nest boxes are closer to trees and shrubs. We might have Brown-headed Cowbirds to count too if those characters lay their eggs in any of the other birds’ nests!
The boxes were only up a day or so when Tree Swallows (Tachycineta bicolor) and Eastern Bluebirds (Sialia sialis) began to explore the boxes. I’m betting they are impressed with the real estate – new construction, a southeast exposure and a security system (metal predator guards to keep out raccoons, snakes, etc.). Between raindrops last Thursday, I watched a pair of Tree Swallows courting on one of the new boxes. They were doing their wet gurgling call to each other the whole time and touching beak-to-beak, while the male performed fancy wing displays. The male had just chased off a competitor, so he seemed excited! It looks like an argument in the photo below, doesn’t it? But I think it was just a lively prelude to mating.
I also found two completed Bluebird nests made of dry grasses in the new Bear Creek nest boxes, but didn’t get to see the female doing the building. However, here’s a little Bluebird female I saw at Charles Ilsley Park the week before bringing nesting material to her box.
Much to my delight, four days later at Bear Creek Nature Park, I found the first egg in one of our new boxes – a Bluebird egg. They lay one egg each day for 3-5 days and won’t start incubating them until all the eggs are laid. The eggs then generally hatch on the same day, making feeding the nestlings more efficient for the adult birds. Remember, please, that only trained and certified volunteers are allowed to monitor the bluebird boxes so as not to cause too much disturbance at the nest!
Holding Prescribed Burns Using Trained Volunteers
The township uses prescribed burns to periodically refresh our fire-adapted native plants, which benefit from periodic fires. Some of these burns are complicated and require hiring professional burn crews. But many are conducted by a group of volunteers trained and supervised by Dr. Ben. In late April, previous volunteer crew members and some new volunteers practiced their skills with two small burns at Bear Creek Nature Park in the native gardens near the parking lot. Volunteers are an important part of the stewardship program and the teamwork is an great way to meet local people who care about the natural world. Consider joining us!
And a Celebratory Dance to End a Busy Month
Toward the very end of April, Dr. Ben arranged our annual Earth Day/Spring celebration: The Woodcock Dance Watch – and wow! This year’s dance was spectacular! This odd bird, with big eyes toward the back of its head, a stout body and a huge beak, does its unique aerial mating dance at dusk.After a short review of information about the American Woodcock (Scolopax minor), we toasted marshmallows while waiting for the sun to set. (Thanks to iNaturalist photographer Ty Smith for sharing his photo.)
This year, one of our birding group members had been making almost nightly visits to Bear Creek Nature Park to watch one particular Woodcock who faithfully danced on the path near a certain puddle. So, as the sky darkened, ten of us gathered on the slope designated by our birder friend, Vinnie, and waited.
Suddenly, very close to us, the Woodcock landed on the path and started his dance. He began with a very odd bug-like buzz called a “peent” call while turning in circles, as he attempted to attract any available female. Then he took to the air with whirring wings, flying in lazy circles high in the air while burbling a different call. Finally he plopped back down right where he started. Without pause he started the “peenting” again, and the dance continued. It was an exciting performance! We all came away feeling it had been an evening well spent celebrating the spring rituals of the natural world.
A Busy Month for Nature and its Stewards
Ah, Spring! Little creatures slip into and out of ponds to begin mating. Seeds await the moisture and warmth they need to thrust new stems into the sunlight. Birds are busy migrating north, establishing territory, finding mates, building nests – even dancing! And we humans are busy studying, recording and preparing their habitat for another glorious summer!
I’m willing to admit that winter walks are a bit more demanding for me. Though I love being out in the open with red cheeks and the glitter of sunlight on snow, breaking through an icy snow crust with every step can be a bit arduous. And as a writer who loves taking photos, well, wildlife is simply a bit more scarce and plant life is a lot less colorful. So the blog creates an interesting challenge. Luckily, I’m all for a good challenge! So this week, in a way, I’m writing about what I didn’t see in February at Charles Ilsley Park. Bear with me…
One February morning, I pursued the paw prints of an unseen coyote who had left a trail in the ice-encrusted snow on the previous moonlit night. And I spent part of an afternoon just noticing the brown and gray architecture of the dry seed heads of some favorite summer wildflowers, now ghosts of their colorful summer selves. Their pleasing shapes provided some inspiration about the native garden I’m dreaming about for next summer. But I’ll start this blog with the handful of birds that I did see, that kept me company on frigid days, just to remind myself that I had sturdy companions on the grayest and coldest days of the year.
Who’s That Twittering in the Tall Grass?
One late afternoon as I approached the Eastern Prairie at Ilsley, I heard the cheerful “chatting” (see first “call” heading at this link) of a small group of winter visitors from the Arctic, American Tree Sparrows (Spizelloides arborea). One of them paused long enough for a good look at its two-tone bill. This little bird had puffed up its down jacket to deal with a frigid morning!
Two days later, the birding group heard more “chatting.” We spotted a large flock of Tree Sparrows flowing like a river from the trees, down into the tall prairie grass. These social flocks keep in contact with short calls back and forth – “I’m here! I’m over here!” – as they forage. I managed to catch a group of them in a vine-laden bush at the edge of prairie.
It was wonderful to watch so many migratory birds feeding enthusiastically on the native seeds of our restored prairie. We were curious to see which plants they were enjoying. That morning they were finding bent Black-eyed Susan stems (Rudbeckia hirta) and plucking out the seeds. Here’s the bent stem at almost ground level, the seeds on the snow and the area trampled by the flock’s small feet.
Actually, this large flock of birds had a few fellow travelers. Dark-eyed Juncos (Junco hyemalis) and American Goldfinches (Spinus tristis) joined the Tree Sparrows’ feast. Larger flocks increase the odds that birds can survive against predators in winter, when birds show up well against the snow. They also mean more eyes spotting good food. (Click on photos to enlarge; hover cursor for captions.)
On a Sunday walk in the Western Prairie at Charles Ilsley Park, my husband and I spotted Eastern Bluebirds (Sialia sialis) diving in and out of the grass. Finally, a pair of them settled on some brush and fallen logs along the tree line. The male ignored me completely while he preened vigorously. Since bluebirds often use the abandoned nests of woodpeckers in the winter, I wondered if he’d picked up some mites from an old nest, poor fellow. I managed to get one quick shot when he rested for just a moment.
The female nearby was keeping an eye on me and as I approached she sent the male a little “chit-chit-chit” call (second “call” heading at this link) that warns of ground predators – me, in this case! Then they both flew off again.
At the far edge of the western prairie, we heard the “ank-ank-ank” call of the White Breasted Nuthatch (Sitta carolinensis). (Under “Eastern calls” at this link.) It was hopping quickly from branch to dead branch above our heads, searching out anything it could eat , like frozen insect eggs or caterpillars.
Now, About Those Tracks Here, There and Everywhere…
As I started out one Thursday morning, I was presented with some pretty impressive tracks. I recognized them immediately, because one of them was mine! The last four birders on the Wednesday morning bird walk had trekked along chatting as we went back to our cars. As a former bookseller, I had to smile remembering Pooh and Piglet tracking a “heffalump” around a bush, which of course turned out to be their own footprints, too. A fun beginning to my search for animal tracks.
I left the trail and headed diagonally across the field following a nice straight line of canine prints – and readers of my previous winter blogs probably know what that means – a Coyote! Coyotes (Canis latrans) trot along at night making a straight trail of prints. Being wild animals, coyotes want to use as little energy as necessary between meals, so they never run around in the snow like dogs do. They place their back feet inside the print of their front feet to use less energy and move directly where they want to go.
Because a crust covered the snow after freezing rain, it was clear that this coyote had to break through the snow with each step, leaving a pointed top to the track it left behind.
I followed the prints as it became apparent that this coyote was headed for the farthest west section of the park, where Stewardship Manager Ben VanderWeide had hired a forestry mower to remove invasive shrubs and create a path to the nearby subdivision for residents’ use. Two trees nicely frame the opening to this newly renovated area.
This western section with its rolling, glacial landscape, wetlands and wooded areas is very different from the open prairies of Ilsley. It seems our coyote thought this might be a better place to rest on an icy, windy night. Coyotes are not really nocturnal animals, but they have learned that night is a good time to hunt and not be bothered by humans and their activities. So I imagine this coyote had been out hunting mice on the prairie and was heading back to the woods to get out of the wind.
After passing into the western area, the coyote turned sharply south into the woods. So I followed its tracks, imagining it trotting between the trees, slipping in and out of the shadows made by the full moon the night before.
It’s easy to see that among the glacially-formed slopes of this rolling landscape, a coyote would be out of the sharp wind that blew across the prairie. The landscape in this area of the park is suddenly so different, as the slopes rise and then descend to one wetland after another. I kept following the coyote deeper into the woods as the line of prints flowed over the slopes.
At last the coyote’s tracks came down to a small pond where they seemed to end in a flattened area under some vines and branches at the right which would have provided a bit of cover.
Beyond that pond was another lovely little pond covered in snow and embraced by the hills around it – but not a track in sight.
I lost the coyote’s trail after that and wandered up to Ben’s path again. I stopped to admire a very tall, wonderfully straight native Tulip Tree (Liriodendron tulipfera) with its closely furrowed bark.
Its yellow blossoms were now dried but still quivering in the wind at the very top of the tree. Ben pointed it out on an earlier walk and told us he thought our area is at the northern edge of this lovely tree’s range. It’s the first wild tulip tree I’ve ever seen.
Nearby stood a tall Silver Maple (Acer saccharinum), its red buds just waiting to expand and bring us one of the first really vivid colors of early spring.
As I left the western wooded area and headed back onto the western prairie, I came across a flattened place in the trail that looked like a major crossroads for critters. The tracks around it were hard to read . I thought I recognized squirrel and possible rabbit tracks, but I have no idea who was there and what was going on, really. Since there are coyote tracks above this flattened area, I wondered if one slept here; as top predators, they do sleep in the open at times. Its warmth would have melted the snow and allowed smaller creatures to get to the ground underneath the crusted surface once the coyote left the scene. Just a guess.
One possible hint was a hole in the snow nearby where a squirrel may have tried to dig up a nut in the frozen soil. Or perhaps our coyote dug up a Meadow Mouse (Microtus pennsylvanicus) before heading off to sleep? I’m not sure because the tracks around it were not fresh; they had been trampled, rained on and frozen.
The coyote tracks did lead away from area toward the private property on the west side of the park.
If the open hole was that of a captured mouse, the birders saw evidence that some mice are luckier than others. Here are some mouse tracks that we spotted near the edge of the western prairie. It looks like this mouse made it safely under the snow’s insulation – safe from the icy wind and out of sight. I love the “stitching” look of mouse tracks in the snow.
On the last leg of my tracking trip to the park, as I approached the central section from the north, I saw one of the spring-fed ponds covered with lots of tracks, making neat, straight lines across the snow-covered surface. What was going on? And then it occurred to me. These were stewardship tracks! Ben had told us at the end of the bird walk that he’d brought a native wetland seed mix to spread on the ponds before it rained later that day. He and Stewardship Specialist Alyssa Radzwion put the seed right on the frozen surface. Native seeds needs to be exposed to the cold before they will germinate properly. Once warm weather comes, the seeds will drop down into the shallow water or moist edge habitat and with luck, begin bringing some color and native plant life to these special areas of the park.
The Ghosts of Summers Past Provide Inspiration for Spring
I’ve begun learning to recognize and appreciate the winter forms of some favorite wildflowers. Their subtle shades of brown or gray as well as their patterns and geometry have started me wondering if I could create a native garden next summer that the birds and I could enjoy all year ’round. It’s clear that birds need the seeds that cling to native plants despite snow and wind. And I could appreciate the architecture of winter plants. So which shapes provide what landscapers like to call “visual interest” and also provide winter food for wildlife?
Perhaps some of you remember how beautiful the Eastern Prairie looked when filled with Black-eyed Susans (Rudbeckia hirta) in the summer. This hardy native has always had a special place in my life. When I was a teenager, the first song I ever wrote included the “wide-eyed stare” of this sunny flower. So it definitely needs to be in my garden. I’m taken with its winter fringed cap in winter and would be happy to let it hang out in my garden.
Black-eyed Susans in bloom
Black-eyed Susan in winter – a lovely cone of seeds for the birds
Mixed in with these bright yellow beauties were the lavender fireworks of Bee-balm (Monarda fistulosa) and they create appealing geometry in a winter landscape.
For contrast, I’d need some white in my summer garden – and maybe good old Yarrow (Achillea millefolium) would be a possibility – if I could keep it from spreading too much. I like its chocolate brown against the white snow.
I love how Yellow Coneflowers (Ratibida pinnata) sway in a summer breeze so I hope they’ll be included somehow too. The plump, oblong seed heads obviously provide forage for the birds and silvery, pointed spears would be a graceful accent in a winter garden.
I may plant Asters in our field rather than in the garden. They grow in such profusion! I’m not sure which of the many Asters is represented in the winter photo below because so many kinds of asters bloom in late summer and fall! They are such a boon to all kinds of butterflies and bees who can feed on them before winter arrives. Here’s just a sampling. (Use pause button for captions.)
Brown-eyed Susans (Rudbeckia triloba), which also bloom late in late summer and fall, might be another good choice for the field, since they grow so tall (compared to Black-eyed Susans) and have a branching form with multiple blooms at the same time.
Well, that’s a start. I want to search out some other favorites, like Foxglove Beard-tongue (Penstemon digitalis) and see what it looks like after bloom – though I doubt I can resist it for the garden. That little Field Sparrow (Spizella pusilla) makes me impatient for spring!
See? Wasn’t that a clever way to get to get some color into an early March blog, when everything is still brown, gray and white? I knew you’d appreciate it…
Finding Delight in a Late Winter Walk
It takes a bit more effort to get out on a frosty morning. There’s all that layered clothing and boots and gloves and scarves. And the early March landscape is getting just a bit tiresome — too much brown and white out our windows. But once I’m out the door and into the landscape, nature offers me a few treats to keep me coming back. Tracking a coyote’s tracks to a secluded pond in the woods feels like a little adventure. The friendly chatting of winter birds keeps me company and the sight of bluebirds in the stark landscape nourishes my color-starved eyes. And how lucky that noticing the winter geometry of last summer’s blooms sets me off dreaming about a new native garden! So all that makes crunching step-by-step through the snow crust worth the effort when the thermometer encourages me to stay home.

Wow! 2018 was another big year for the Natural Areas Stewardship program. We completed botanical inventories of several small parcels. The Land Preservation Millage was renewed for another 10-year term. Major invasive shrub control projects began at Bear Creek Nature Park, Blue Heron Environmental Area, Charles Ilsley Park, Paint Creek Heritage Area – Wet Prairie, and Stony Creek Ravine Nature Park. Volunteers monitored vernal pools, lakes, and nest boxes. Our fire crew gained experience and was able to complete several burns in the spring. Our planted prairies from 2015 really started to look like prairies in 2018. And the word continued to spread about our natural areas stewardship program and the wonderful, consistent support from our township residents. What fun! Check out the highlights of the year below, or read the full 2018 Annual Stewardship Report. (Click link to view). The table of contents in the PDF is hyperlinked to help you navigate the report.
Volunteers contributed 1212 hours in 2018! Weekly bird walks continued, gathering useful data about avian life in the park and engaging residents. Volunteer workdays focused on garlic mustard (May), invasive shrub control (July to November), and seed collecting (October). Volunteers also monitored nest boxes at Draper Twin Lake Park, Charles Ilsley Park, and the Paint Creek Trail; monitored vernal pools at Bear Creek Nature Park; and monitored water quality at Lost Lake and Twin Lake. We had fun at summer and winter potlucks and the December birder coffee hour!
The nest box monitoring program was made possible by volunteer Tom Korb, who built, helped install, and Charles Ilsley Park, Draper Twin Lake Park, and the Paint Creek Trail. We enjoyed watching bluebirds and tree swallows nesting in these new boxes!
Prairie Restoration with USFWS Partners for Fish and Wildlife Grants
After planting 55 acres of prairie reconstructions in 2015 and 2016, we completed our third round of plantings in 2018. Using our second Partners grant, we planted an additional 15 acres at Charles Ilsley Park and 3 acres at Gallagher Creek Park in May 2018. We continued maintenance of areas planted in 2015 and 2016, working to give native plants the upper hand during the critical establishment phase.
We contracted with Plantwise LLC for spring burns at Cranberry Lake Park(40.4 ac), Lost Lake Nature Park (24.6 ac), and Paint Creek Heritage Area—Wet Prairie (9 ac). We also worked with private landowners to burn 13.1 acres of habitat adjacent to the Paint Creek Trail right-of-way, including high quality oak savanna, prairie remnants, and fen wetland. We held volunteer prescribed burn crew training again in February. The volunteer crew completed burns at Bear Creek Nature Park (23 ac), Charles Ilsley Park (1 ac), Draper Twin Lake Park (9.4 ac), Watershed Ridge Park (2.4 ac), and Paint Creek Trail at Gunn Road (0.4 ac).
The stewardship blog continued to thrive, with regular posts from Cam Mannino. She regularly highlighted cool features across all of our parks, all with excellent writing and photographs. The blog also continued to serve as an up-to-date source of information about stewardship volunteer opportunities and events. We published 45 posts and had 6233 visitors, with 11,744 page views.
Stewardship talks included presentations on native bees, rain gardens, prescribed fire, emerging invasive species, bird nest box monitoring, and oak wilt. We enjoyed a pleasant April evening at our annual Woodcock Watch at Cranberry Lake Park.
Phragmites Outreach Program
We continued the Phragmites Outreach Program to help township residents get Phragmites treated on their property. We received about 32 requests for no-obligation cost estimates, and treated about 25 properties with a contractor, PLM Lake and Land Management.
Billy Gibala returned to our crew through June. He graduated from University of Michigan-Flint in 2017 with a degree in wildlife biology and minors in regional and urban planning, We welcomed Alyssa Radzwion to the crew. She graduated from Oakland University in December 2016 with a Bachelor’s degree in biology, and had previous experience working for the Michigan DNR stewardship crew. Katlyn Hilmer recently graduated from State University of New York College of Environmental Science and Forestry, where she focused on forestry work. Sarah Rosche joined the crew in July after completing her Master’s, studying the effects of fire on Northern Bobwhite nesting ecology and habitat selection. We had a great crew with diverse experiences!
All of our annual reports can be found on the About page.
Bear Creek Nature Park can be surprisingly busy on a late autumn afternoon. Couples sit chatting on a bench, while pairs of other species are gliding together on the Center Pond or cozying up in the hollow of a tree. Birds soar overhead or chatter from distant branches.
And meanwhile on the north side of Bear Creek, Oakland Township Stewardship Manager, Dr. Ben VanderWeide, along with hard-working volunteers and a forestry mower, are ridding the park of invasive shrubbery. And what emerges from their efforts is a beautiful, rolling oak savanna landscape! You may be a bit shocked at first by the change – but trust me, you’re going to love it!
Pairing Up in Autumn
Spring may be for lovers but autumn’s got its own appeal. One late afternoon, a young couple came wandering down a forest path toward me, the girl giving me a shy hello. And shortly thereafter, as I approached the north platform of the marsh, a slightly older pair of friends relaxed on the bench, just enjoying together the golden light of an autumn day.
Nearby at the Center Pond, the Mallards (Anas platyrhynchos) were paired up as well. Mallards choose their mates in the autumn once they’ve finished their molt. They won’t mate until the spring, but they spend the winter hanging out together. Kind of nice, really….
A third couple showed up in the comfortable, big hole in a White Oak (Quercus alba) where I’ve often seen Raccoons (Procyon lotor). They were looking pretty cozy as the sun went down. You may see only one in the photo below at first, but note that there’s a third ear showing! The second raccoon, sleepier or less curious than its companion, stayed hidden behind the first. Raccoons are generally solitary but they occasionally den up together and sleep through cold snaps, especially in December and January. They don’t actually hibernate, which would involve slowing down their metabolism for a continuous period. This sleepy-eyed raccoon could be a female and its kit; the young generally stay with their parent for close to year. But from their size, I’m guessing it’s two young raccoons of the same sex – they den that way too – just waking up as the night comes on.
More Birds and a “Bear” of Sorts…
As I approached the pond one afternoon, a flash of slate blue and a ratcheting call alerted me to the presence of a Belted Kingfisher (Megaceryle alcyon). Though Cornell tells me I should see them year ’round, I only seem to spot them in the spring and the fall. Again this time it was a noisy, solitary male; kingfisher mating pairs only associate in the breeding season. He stayed off in the distance but I could tell it was a male from the single blue band on his chest. Females have two bands, one blue and one chestnut brown.
A Red-tailed Hawk (Buteo jamaicensis) circled high above the eastern meadow, scouting for a snack before nightfall.
On a snag near the marsh, a female Downy Woodpecker(Picoides pubescens) drilled for her evening meal. Downys look a lot like Hairy Woodpeckers, but are smaller and have shorter, sharper beaks and dark dots on their outer white tail feathers. Hairy Woodpeckers have a longer, heavier, spike-like beak and clear white feathers on the outside of their tails.
During the bird walk at Bear Creek Nature Park two weeks ago, we were treated to the sight of a good-sized flock of Eastern Bluebirds (Sialia sialis). At first we saw just one of two.
And then Ben spotted a whole flock on the western slope where they eventually landed in a single tree, as if decorating it for the holiday season!
A couple of migrants had arrived as well. The Tree Sparrow (Spizella arborea) had just arrived from Alaska or Hudson’s Bay where it raised its young this summer. This bird loves cold weather but the far north is too extreme even for Tree Sparrows at this time of year, so it traveled south to relax in a balmly Michigan winter!
Another migrator was just passing through. I didn’t catch a photo two weeks ago, but here’s a photo of the White-throated Sparrow (Zonothrichia albicollis) from a previous autumn. Notice the yellow lores above its eyes! Handsome bird!
And About that Bear…
As you know, there are no actual bears in Bear Creek Nature Park. But there is, of course, the Wooly Bear, the caterpillar of the Isabella Tiger Moth (Pyrrharctia isabella). I have a particular fondness for these little creatures because they so often introduce children to the pleasures of nature. Wooly Bears, as you may recall, curl into a ball if handled as a defensive move. So placing one in a child’s hand often elicits surprise and laughter as the bristles of its brown and black hair tickles a youngster’s palm. In fact, I recently saw this happen to little children at Gallagher Creek Park. So here’s Bear Creek’s only bear, at last.
Volunteers Open New Vistas at the Marsh
When farm fields were abandoned in the township decades ago, aggressive non-native shrubs quickly took over the fields and surrounded wet areas. Bear Creek Marsh has been surrounded by these non-native shrubs for many years. But in late October, Six Rivers Land Conservancy and a group of industrious volunteers from Fiat-Chrysler helped Ben VanderWeide and stewardship specialist Alyssa clear huge thickets of glossy buckthorn from the edges of the marsh at the eastern edge of the Oak-Hickory forest. (Click on photos to enlarge; hover cursor for captions.)
FCA volunteers worked with great enthusiasm to cut buckthorn at Bear Creek Nature Park.

The crew created huge piles of the invasive shrubs which Ben plans to burn during the winter months. The stumps of the buckthorn shrubs were carefully treated. As you can see above he uses a blue dye with the treatment to be sure he’s covered the stumps completely in order to prevent re-sprouting.
The end result of their remarkable effort is that we have wonderful new views of the marsh which we could never enjoy before! And, of course, other native plants can thrive at the edge of the marsh!
An Oak Savanna Emerges from a Tangle of Invasive Shrubs
Before farming came to Oakland Township, the landscape was defined by tall native grasses, native wildflowers and widely spaced oak trees – what is called an “oak savanna.” That grassy, open landscape is just beginning to be restored at the north end of Bear Creek Nature Park – and it is just spectacularly beautiful!
Until last week, invasive Glossy Buckthorn shrubs filled the entire area surrounding the Center Pond, just as it had surrounded the marsh. Starting at the edge of the forest, the Buckthorn and a few other invasive shrubs formed super dense thickets filling the entire loop trail and the trail edges up to the forest. The photo below, taken the first day that the major restoration began, shows just how densely the Buckthorn had grown!
Because of those shrubs, the trails had become tunnels between non-native vegetation. Here are the two arms of the Big Northern Loop and the trail behind the pond as they looked before restoration began and how they look now after we started the restoration process.
Eastern Trail on the Big Loop
Western Trail on the Big Loop
Trail Behind the Center Pond
Before the forestry mower arrived, Ben carefully marked the trees to be saved and the areas filled with invasive shrubs that required removal. The operator of the mower, an employee of the Ruffed Grouse Society that owns the machine, carefully avoided the trees Ben had marked and even preserved other young oaks that he found buried in the thickets. As the mowing proceeded, what gradually appeared behind it was an oak savanna – oaks and a few other trees sprinkled across a plain – the very type of landscape that thrived here hundreds of years ago! All that’s needed are tall native grasses and wildflowers.
When Ben took me last week to see what had begun, I was astonished and delighted to discover vistas that I’d never known were hidden beneath all those shrubs! Here’s the western loop trail stretching south toward the pond. Now I could see a cleared meadow dotted with young oaks and other trees with the edge of the forest on the perimeter. What a difference from walking through a tunnel of buckthorn!
I could stand in the center of the loop which had been an impassible tangle of shrubs and look south down an undulating slope to the whole expanse of the Center Pond, a viewpoint I’d never had before!
When Ben and I left the western loop heading back up the trail toward the south, the forest stood tall beyond the newly cleared field. We could now see the forest, a dark wall of hickories and oaks, that embraced the new landscape. We were no longer inside a tunnel of shrubs that blocked everything but the treetops beyond. Ben looks pretty pleased with the work after the first day of restoration, doesn’t he? He should be!
A Landscape Resurrecting
When I followed that path around to stand again on the observation deck at the Center Pond, I realized the scope of the transformation emerging at Bear Creek. Now the graceful, flowing curves of the landscape began to dip and rise in graceful curves beyond the pond. These three photos together can give you some idea of what I saw standing there, looking north from west to east across the pond.
I’m guessing that you can tell I was thrilled at the transformation taking place at Bear Creek. I have walked this park for over 25 years and at one point, I walked it every day for 3 years. It’s essentially my “home park,” and I know it intimately. So when Ben first talked of changing it, I was skeptical. When I came to see the first day’s restoration work last week, I actually stopped in my tracks as I came to the pond and gasped – and then I began to smile. That smile never left my face as I wandered through a vastly changed Bear Creek that for me had suddenly become even more beautiful. The feeling of “rightness” was so powerful. This, I felt, was the way this land was meant to be. It seemed as if the earth could take a deep breath, that the oaks that had been hidden among the tangle of shrubs were now stretching to the sky, ready to grow taller and stronger in the sun and the wind.
It will take years of hard work to complete this transformation. Buckthorns don’t give up easily. This winter Ben will plant native grass seed among the shards left from the shrubs, the broken wood eventually returning its nutrients to the earth. In the spring, the buckthorn will vigorously produce sprouts again and Ben and his crew will have to persist in keeping the ground that they gained for the oaks, the native plants and the wildlife.
Eventually, when the shrubs have subsided, Ben can plant the area with native wildflowers. Turtles will emerge from the wetlands to find soft soil in which to dig their nests and lay their eggs. The native plants will slowly sink their roots deep enough to survive fire and drought. And if we’re patient and lucky, they will finally come to full bloom. And that’s when we’ll be able to see birds and butterflies fluttering and floating between and above the oak trees, over the rolling grassland – some perhaps that we haven’t seen in a long time. And won’t that be a sight to see?
Standing hip-deep in native grasses and wildflowers is a pretty terrific way to spend a few hours on a cool autumn afternoon. Every fall our township Natural Areas Stewardship Manager, Dr. Ben VanderWeide, plans a few days for harvesting the seeds of native wildflowers to plant in our parks over the winter and the following spring.
So this October, volunteers gathered, clippers in hand, paper bags at the ready, to chat quietly as we snipped the seed heads from native prairie flowers. Can you see two of our seed-gathering volunteers in this Where’sWaldo-style photo?
It always makes me feel like a child again to stand in a field with friends and have native grasses towering over us. Here’s our township Stewardship Specialist, Alyssa Radzwion, smiling through a scrim of native grass.
On the day pictured above, we harvested seeds from Black-eyed Susans (Rudbeckia hirta), Gray-headed Coneflowers (Ratibida pinnata), Foxglove Beardtongue (Penstemon digitalis), and several other native plants.
Harvesting native seeds is good stewardship. Ben instructs us volunteers to collect an appropriate amount for each species, leaving lots of seeds where they are to feed wildlife and renew our prairies so they look as glorious next spring as they did this year! The seeds we harvest, along with purchased wildflower seed, can then help restore more of our natural areas to their former glory. All that and peaceful autumn afternoons among wildflowers and kindred spirits. Maybe you’d like to join us next year as we lend nature a helping hand?
