April is the month when every day seems to bring a new bird flying into the woodland, a new amphibian calling from the pond, a new mammal poking along the river, a new insect hatching in the prairie, and, most of all, a new plant unfurling from the forest floor.
April through the end of May provides ideal conditions to enjoy spring wildflowers. These plants are also called “ephemerals,” which means “lasting for a very short time.” Spring ephemerals take advantage of abundant light in the woodland before leaves emerge in the canopy above. Ephemerals complete their entire life cycle before shade covers the forest floor.
If you haven’t visited your favorite Lake County Forest Preserve lately, come along with me on this virtual wildflower walk to see what’s blooming now and what’s to come.
Many years ago, while hiking through a prairie at dusk, I saw a stalk of delicate white flowers. They seemed to rise and hover above the surrounding plants like a group of little dancing ghosts. This was the first and last time I ever saw an eastern prairie fringed orchid (Platanthera leucophaea). Due to its dwindling numbers and hidden habitats, this rare plant has reached almost mythical status—a holy grail of sorts in the Midwest. We’re thrilled that this endangered native orchid seems to be gaining a foothold in the Lake County Forest Preserves, which are home to some of the largest remaining populations. Just this month, one of our restoration ecologists discovered an orchid in bloom (photo below). It was found at one of the preserves known to provide habitat for this species but is the first documentation of a population at the site.
September in Lake County, Illinois is a month of big sky punctuated by tips of tall prairie plants in an array of autumnal colors. Before the trees really get going with their own colorful show, sparks of bright yellow from the many varieties of goldenrod (Solidago spp.) dominate the open spaces. Most of the summer these plants go unnoticed, adding merely another green hue to the lush surroundings, but September is their time to shine. What may also go unnoticed, even now as goldenrod demands our attention, is the hidden world inside each plant in the form of a gall.
Last week while visiting Lyons Woods, I noticed that a large patch of garlic mustard was quivering. When I got closer, I found that it was not the breeze making the plants sway, but rather a huge group of red admiral butterflies (Vanessa atalanta) flitting from flower to flower. In many areas, all you have to do is walk out your front door to witness the population explosion of these ubiquitous butterflies that is sweeping the northeastern United States this spring.
During a training hike for volunteer nature guides last week, a fellow naturalist pointed out a series of pea-sized holes in the ground. I walk along this same trail regularly and had never noticed them. As our group stooped around these holes, shivering on this cold but sunny spring morning, a tiny head crept slowly out of the one of the holes. It was the head of a mining bee! Continue reading →
Don’t get me wrong, I love spring, but the first signs of green to shoot out of the leaf litter stink! While this spring seems to be on fast-forward, with many woodland wildflowers appearing almost to six weeks early, the first plants to sprout in Lake County were still the stinky duo of skunk cabbage (Symplocarpusfoetidus), and Chicago‘s supposed namesake, wild leek (Allium tricoccum). The Native American tribes of this region called the plant in question “shikaakwa” or “chicagoua”.
