Watershed Ridge Park: Restoration Off to a Colorful Start!

 

Wildflowers re-establish themselves in a meadow at Watershed Ridge after invasive shrubs are removed

Watershed Ridge, at the corner of Lake George and Buell Roads, is not yet an accessible park. Trails have yet to be created for exploring its forests, wetlands and meadows, though they are planned for the future. Large areas of the land are still under cultivation for agriculture; local farmer, John Fogler, rents fields within the park to plant soy beans and pumpkins. (Click on photos to enlarge; hover cursor for captions.)

But last fall, our Natural Areas Stewardship Manager, Ben VanderWeide, began removing an almost impenetrable cover of invasive bushes that had taken over part of this beautiful piece of land. And suddenly, the graceful contours of the land came into view.

The rolling slopes looked lifeless then. But what a transformation this spring and summer as sun finally reached the native wildflowers!

Part of the reason Ben chose this area for restoration was that he’d noticed unusual native plants struggling to survive in the shade of invasive bushes like autumn olive, glossy buckthorn, privet, and such. Last autumn, Smooth Aster (Symphyotrichum laeveand a small orchid called Ladies’ Tresses (Spiranthes species) thrust their stems into the cool air. (Here’s a photo of the little orchid as it looked at the Wet Prairie on the Paint Creek Trail.)

Ladies Tresses, a small orchid, is a fall wildflower that Ben saw at Watershed Ridge last autumn.

Right now I’d advise anyone to be cautious about  walking through Watershed Ridge since it’s easy to get disoriented on 170 acres without trails (though a compass in your phone helps, I find!). Hikers need to use the edges of the farm fields so that they don’t damage the crops. The woody debris on the ground makes walking a bit tricky  and there’s a fair amount of Poison-ivy (Toxicodendron radicans) to avoid. Photos below might help those afraid of all 3-three-leaved plants. The one on the left is poison ivy.  Note the “thumb” on the leaves which is missing from other three-leaved plants like the Black Raspberry (Rubus occidentalis) on the right. Poison-ivy often has reddish “feet” when it’s climbing a tree and grows along the trunk rather than around it.

So for now, perhaps consider an easier alternative.

Birds Grace the Simple Entrance off Buell Road

The best spot to park is on Buell Road at the firewood pickup site (1650 W. Buell Road is the approximate address – click here for a map). Just to the west you’ll see a work area for Parks and Recreation staff that includes a pole barn and bulk materials storage. This work area is closed to the public, but you’re welcome to explore the rest of the park.

The old fence rows near the entrance on Buell Road have many trees, shrubs and vines, so birds nested happily around the area this summer. In mid-July, this area was full of fledglings trying out their wings and pestering their parents. A flock of young Eastern Bluebirds (Sialia sialis) settled on limbs and fence posts, begging to be fed while their beleaguered adults either surrendered or tried to escape their noisy youngsters. (Click on photos to enlarge; hover cursor for captions.)

A young Eastern Phoebe (Sayornis phoebe), however, was off on its own, trying out its wings, exploring the pole barn (sheds are popular Phoebe nest sites) and flying down into the grass like any adult Phoebe might.

A young Downy Woodpecker (Picoides pubescens) was also off on its own and looking a bit dubious about what to do next as it sat in a nearby pine. This may be a young male since it appears that its juvenile red cap is slowly receding into the red spot that a male sports on the back of its head.

I failed to get decent photos, but two weeks ago, a pair of Cedar Waxwings (Bombycilla cedrorum) were still feeding their nestlings, flying back and forth between a tree on the west side of the area to a large willow on the east where they probably were foraging for insects before returning to the nest. Here are two not-so-hot photos!

From mid-July to mid-August, American Goldfinches (Spinus tristis) raise their young. Unlike most native birds, they wait until mid-summer to breed, because they like to line their nests with thistle down, eat the seeds themselves and feed them to their young. Several were flitting among the thistles along Buell Road.

A “High Quality” Woodland Sprinkled with Wildflowers that Love Moisture, Shade and Rich Humus.

When you step into the cool darkness of the woods on a warm summer afternoon, you notice that most of the plants bear modest little flowers compared to sunnier areas. Perhaps that’s because they’ve  evolved growth and reproductive strategies that are different from the large, colorful blooms of a sunny meadow or prairie.

One good example is the unusual flower of a parasitic plant (not a mushroom!) that Ben helped me find, called Indian Pipe (Monotropa uniflora). This small, white wildflower typically grows in forests and lives on the photosynthesis of trees – especially oaks in our area – by tapping into the  mycorrhizal fungi that connect the trees below the soil. As a result, it doesn’t use photosynthesis and contains no chlorophyll. According to the Illinois Wildflower website (a descriptive floral site), “This unusual wildflower is normally found in high quality woodlands” where there is “abundant humus.”  Hooray for Watershed Ridge, eh?

The modest blooms of summer woodland plants primarily attract small bees, like sweat or carpenter bees,  or flies,  rather than honeybees or bumblebees.  They also frequently spread by rhizomes (underground stems) and/or by making bur-like fruits that will stick to any passing animal, including you!

Wildflowers that enjoy dappled light find a home where the woods meets the now-open meadow.

Naturally, mushrooms also thrive in shady, moist places. Near the edge of the woods, I saw what I think are two kinds of highly toxic mushrooms from the genus Amanita. I believe they are either Amanita phalloides or Amanita bisporigera. In any case, Amanita mushrooms are also called “death caps” for good reason –  so admire their exotic strangeness, but leave them right where they are. The yellow one may have been nibbled by squirrels or rabbits who can eat the toxins with no problem.

Wetlands Glow Blue/Green in the Deep Shade of the Woods

One of the wetland pools within the woods at Watershed Ridge

Two wetland pools shine in the darkness on either side of a ridge within the woods at Watershed.  Near the western one, an old log is festooned with a huge number of tiny, stalked mushrooms which I can’t identify. They make quite a show against the dark, wet decaying log on which they are thriving.  (Anyone have an ID for me?)

Ben saw two snappers on a log in one of these woodland pools, but they dove in before I saw them. I did see some of my favorite frogs, though. A small female Green Frog (Rana clamitans) (left) basked on a fallen log, while a male nearby (right) did the same. In the female, the tympanum (circle behind the eye used for hearing) is about the size of her eye; the male’s tympanum is about twice the size of his eye and he has a yellow throat.

At the eastern pool, a tiny, black-masked Wood Frog (Rana sylvatica), perhaps 1/2 inch long, paused for its photo on a leaf. This one’s back and legs are bright green, perhaps from the Water Meal (Wolffia columbiana) or the algae in the pool nearby. It seemed an odd time of year  to find an early spring frog, but Wikipedia says that  occasionally Wood Frogs do breed more than once per year. Maybe the heavy rains contributed to more water and hence more breeding behavior? Just a guess.

At the edge of the soybean field just beyond the wood, every step scared up hundreds of small Northern Leopard Frogs (Rana pipiens). They sprang out of moist grass and huddled beneath the bean plants. These young frogs  take about 70-110 days to develop after the females lay their eggs in the water between May to June. At about 2 inches long, they’re half the size of a mature Leopard Frog. Their numbers have generally been in decline since the 1970’s so what a delight to see so many of them here in the township on a protected piece of land!

A Riot of Color as Wildflowers and Butterflies Reclaim a Wild Meadow

Black-eyed Susans and Butterfly Milkweed “take the field” after invasive shrubs are removed from Watershed Ridge

Step out of the woods and the colorful signs of restoration engulf you. Once shaded-out by invasive shrubs, native wildflowers like Black-eyed Susans (Rudbeckia fulgida) and Butterfly Milkweed (Asclepias tuberosa) in the photo above sprang back into the sunlight that finally reached them.  So exciting to see these plants come back with such vigor in the first season after the invasives are removed! (Use pause button to read captions.)

And with the wildflowers, of course, come the butterflies – but first, one glorious moth! When I first spotted this unusual creature, I thought it must be some sort of bumblebee. But no, it’s the Snowberry Clearwing Moth (Hemaris diffinis). It has fewer central scales on its wings than other butterflies or moths so the wings appear clear in places. It’s odd shape and hovering flight have also inspired the names “the hummingbird moth” (not to be confused with the European one of the same name, Wikipedia tells me!) or the “flying lobster!”  A new creature for me!

This is not a bumblebee. It’s a Snowberry Clearwing Moth mimicking one!

On my first summer visit with Ben, we saw a glorious Eastern Tiger Swallowtail (Papilio glaucus) sipping from some of the bee balm which emerged in great waves of color across the restored meadow this summer. What a sight!

A female Eastern Tiger Swallowtail sips nectar from the great swath of bee balm that now flows across the restored meadow.

Having seen the Spicebush Swallowtail butterfly (Papilio troilus) for the first time at Charles Ilsley Park a few weeks ago, I saw another male at Watershed Ridge.  The clue is the wash of blue scaling on the wings. A week later I saw another one near the shed which was either the female, which has a less intense wash of blue scaling, or a tattered male who had already lost some of his scales. That Spicebush continually tried to chase off a female Monarch (Danaus plexippus) who was patrolling the same patch of flowers last weekend. The scales on her wings looked quite worn as well. Perhaps they’d worn each other out with all that chasing! I saw some fritillaries dancing together at a distance but not close enough for a shot. But the little Orange Sulphur  (Colias eurytheme) was kind enough to pose for a few moments.

The meadow slopes down to a sunny wetland that is probably fed by the creek running through the trees just east of the meadow. The stream bottom is bright orange, most likely a result of iron deposits in the soil. I loved how the sky was caught in the water’s surface as I looked upstream.

The resulting wetland at the meadow’s edge featured flowers that love “wet feet,” like Joe Pye Weed (Eutrochium maculatum) and Boneset (Eupatorium perfoliatum).

With a wetland nearby, dragonflies, flying predators, swooped across the meadow on the hunt for other insects.

A Meadow Under Restoration Gets Us Dreaming

Witnessing the dramatic renewal that takes place when invasive shrubs are removed from park land is simply inspirational. What else, who else might return to this lovely piece of land once the Parks and Recreation Commission has time and the funds to develop this 170 acres? What seeds are waiting in the seed bank for their turn in the sun – perhaps even this autumn when the asters in their varied lavender-to-purple blooms or other autumn wildflowers rise from the earth? What other exotic creatures like the Snowberry Clearwing Moth might be sipping at future flowers? What birds might return to nest here? The possibilities are endless as the Ben and the Parks Commission work to renew the diversity of life which is our township’s natural heritage. So much to look forward to as this park progresses over the next several years!

THIS WEEK AT BEAR CREEK: Golden Fields Full of Monarchs, a Hummer and Other Beauties and Curiosities

Open fields edged by trees have always been favorite places of mine.  And this Tuesday,in the fields on either side of the park, Monarch butterflies were everywhere!  Bear Creek may be hosting fall migrators on their way to Mexico – or we’ve just had a big hatch of  these beautiful and ecologically fragile creatures.  In fact, many butterflies, bees and darners fluttered, hummed and hovered over the swaying seas of gold in Bear Creek, while grasshoppers serenaded them beneath the tall stems.

Some speculate that humans love open fields because our ancient ancestors felt safe where they could see into the distance but escape into the trees.  I just know I’m very happy in a field full of wildflowers.

First, of course: The Monarchs and the Hummer!

After only seeing the occasional Monarch Butterfly (Danaus plexippus) this summer, on Tuesday they were floating and fluttering all over the park!  Though the Joe Pye (Eutrochium maculatum) in the Eastern Old field seems to be past its peak,  its nectar drew in a Monarch (and other butterflies below) anyway.

I considered myself lucky to get so close – but when I started down the Western Sloping Path from north to south, wow!  Monarchs surrounded me every step of the way.  I believe I saw at least a dozen there, but I’ll share just a few who were enjoying the New England Asters.

At the very bottom of the sloping path, I watched as two Monarchs approached and fed on the same plant.

Just at that special moment, I saw the second Ruby-Throated Hummingbird (Archilochus colubris) I’ve ever seen at Bear Creek – a female, hovering momentarily as she looked at me and then zoomed off toward the woods.  No photo, of course, but perhaps this silhouette of a hummer in mid-hover from a few years ago will help you visualize the one I saw this week.

Fields Full of Wildflowers and their Beautiful Visitors

Eastern Tiger Swallowtails (Papilio glaucus) fluttered quickly across the golden fields.  I just caught sight of one in the far distance on the Eastern Path on Sunday so here’s a picture from another  August, when a male landed on Spotted Knapweed, an invasive wildflower.

About That Hum in the Old Fields…

Honey Bees (Apis mellifera), native Bumblebees (genus Bombus) and even Eastern Yellow Jacket Wasps (Vespula maculifrons ) hum among the flowers in the Old Fields.  Don’t worry; they’re much too busy gathering pollen, or in the case of wasps, eating nectar, to bother with us humans.

Always on the lookout for a quick munch, the big Canada Darner Dragonfly (Aeshna canadensis) zooms and dives over the blossoms below. This B-52 of insects consumes a lot of late summer bugs.

Below the Darner, a modest wet-footed flower stands among the wetland reeds in the Eastern Old Field. According to Wikipedia, Boneset (Eupatorium perfoliatum) got its name because our ancestors believed that since the leaves clasped the stem “wrapping the leaves in bandages around splints would help mend broken bones.”

Reportedly Boneset got its name from a past belief that because the leaves clasp the stem, it would help with mending broken bones.

Down in the grass, the Red-legged Grasshoppers (Melanoplus femurrubrum) sing lustily as a backdrop to all this beauty by rubbing their rasp-like back leg against their forewing.

Yellow Jackets, like all wasps,  don’t do much pollinating because they lack the fuzzy body hair of bees.  They generally eat nectar but collect bugs for the protein they feed to their young.

What’s That Bump on the Goldenrod, Anyway?

As you’re wandering through the Old Fields, you may have noticed some strange shapes on the stalks and tips of Canada Goldenrod (Solidago canadensis).   Galls are growths on plant stems caused by insects who lay their eggs on the plants in the spring.  When the larva hatch, they eat into the plant, causing it to form a gall around them.  Inside, the larva eats until late summer when it forms a pupa which spends the winter inside that protective covering.  In spring, the adult insect emerges to restart the life cycle. Galls don’t kill the Goldenrod; they just look funny!

The ball gall is the most common goldenrod gall and is formed by  the small Goldenrod Gall Fly (Eurosta solidaginis).  With its hard surface, this gall seems like a decent place to spend the winter, doesn’t it?  During the summer, though, some wasps lay eggs in galls and their larvae hatch and make a meal of the gall fly’s.   And in the winter,  Downy Woodpeckers drill holes in galls to reach the pupae,  and Gray Squirrels chew on galls to do the same.  Obviously enough Gall Flies survive in these dwellings to start a new crop next spring, so nature stays in balance. I think this gall may have been invaded by a wasp.

Goldenrod gall2
A ball Goldenrod gall formed by the larva of a Goldenrod Gall Fly who turns into a pupa and spends the winter there – though the holes indicate that perhaps a wasp has invaded this gall and its larva may have eaten the gall fly’s.

Goldenrods also harbor the very tiny (.2″) Goldenrod Gall Midge (Rhopalomyia solidaginis) which causes a rosette gall.  Once the grub of this tiny creature hatches, the stem of the goldenrod generally stops growing but keeps producing leaves which bunch up and make a nice hiding place for a midge’s larva to grow – along with spiders and other midges who may move in.   Sometimes, as in this photo, the stem will continue to grow above the rosette gall, but it’s much more spindly.

A rosette gall on Canada Goldenrod created by a single tiny insect but potentially a hiding place for other midges and spiders as well.

For years I saw willows in the park that seemed to be producing pine cones at the end of their branches.  Turns out they’re Willow Pine Cone Galls, made by a tiny (about .2″) midge scientifically known as Rhabdophaga strobiloides.  The pine cone-shaped gall that its larva causes can harbor many species.  According to the University of Wisconscin-Milwaukee’s Field Station website, “Beetles, caterpillars, sawflies, cynipid wasps, midges, and the eggs of meadow grasshoppers have been found inside pine cone galls.”  They’re now on a willow on the west side of the Center Pond and can also be seen in the wetland area east of the Eastern Path.

gall
No, not a pinecone! A Willow Pine Cone gall that can harbor over 30 different species besides the larva of its original midge.

The Eastern Old Field rolls down to the Center Pond and the Western one slopes dramatically to the west.  The trails that wind across them are full of strange and beautiful creatures and the plants that feed on and live in them.  Walk quietly. Look closely.  Listen carefully.  And when nature shares a secret with you, please share it with the rest of us.
