Late spring and early summer are busy seasons for children visiting the Lake County Forest Preserves for pond study programs. The shorelines of ponds pulse with the excitement of students, nets in hand, ready to discover the macroinvertebrates teeming under the water’s surface. The most delightful find this season by students has to be what Henry David Thoreau once called the “submarine cottages” of caddisfly larvae.
Spring seems to be a bit accelerated this year in the Lake County Forest Preserves. Trillium are already blooming at Ryerson Woods. Yesterday, I even saw a tiger swallowtail butterfly, wafting its way through the dappled light of the forest. Both of these species are typically associated with mid-May. With earlier than usual spring weather comes earlier than usual “tick season.” Like the trillium and swallowtail, ticks are a part of our natural areas.
By learning more about ticks, along with some mindful actions before you head outside, interactions with ticks can be minimized so our enjoyment of the outdoors can be maximized.
Contrary to what many people think, ticks are not insects. They are arachnids. Like spiders, they have two body parts and eight legs. In addition, ticks have intricate mouthparts designed to bite and hang onto their host, which can be any warm-blooded animal in the area, including us. Continue reading →
Just like fish stories, it seems everyone has a skunk story to tell. I have many, but my favorite one happened a few years ago in the spring, when I was getting ready to teach education programs at Greenbelt Forest Preserve. Before the students from a local school arrived, we were busy unloading supplies and setting them out around the preserve. When we returned to the van, we found a skunk sauntering right up the open lift-gate, looking curiously like he might climb in! We froze, chanting in a hushed tone to ourselves, “Please don’t go in there, please don’t go in there.” Either our chants worked, or he realized the preserved insects in the cases he was checking out were not a good meal. He casually wandered back to the brushy field and was long gone by the time the bus arrived.
I remember the first time I saw it happen. It was a frigid Sunday in February, sixteen years ago. I had just started working for the Lake County Forest Preserves. The deep cold, the kind that temporarily freezes your eyelashes together every time you blink, kept potential hikers away from Ryerson Conservation Area that day. I ventured out only to fill the bird feeders, and the chickadees, juncos, cardinals, and woodpeckers quickly gathered around for a feast. I thought they would be my only visitors of the day. Then, a cacophony of bird wings ruptured the quiet. Bird visitors fled from the feeders in all directions. In a low hanging branch of a nearby oak, one bird remained: a Cooper’s hawk. It was devouring a mourning dove that had just been pecking around under the feeders only moments before.
My family and I spent the beginning of the new year in the Northwoods. We wanted quiet. We wanted nature. Most of all, we wanted snow. As we started out on a snowshoe trek to a nearby river, tiny snowflakes settled on my son’s navy blue parka. They seemed to freeze on contact for only a few seconds, forming miniature constellations, before melting into temporary teardrop stains. The filigree of each flake in those hushed, fleeting moments fascinated both of my boys.
It is officially a new winter. To celebrate the biological diversity protected within the Lake County Forest Preserves in northeastern Illinois, we’ve put together a few of our favorite images from 2016. To see even more of our favorite images, … Continue reading →
