Appreciating Muskrats

What might a muskrat be doing in an urban park, just blocks from the center of town? Muskrats occupy a wide variety of aquatic and wetland habitats, including slow moving creeks near cities and towns.

Monarch Butterflies are declining rapidly as a species—by a staggering 90 percent in the past two decades. Butterfly milkweed, an easy-to-grow perennial characterized by attractive foliage and bright orange flowers; it is also the only plant fledgling Monarch caterpillars feed on.

Two Ways to Fight Invasive Plants

Speak out to protect the Middle Fork

The “skunk cabbage,” is a plant that lives up to its name, giving off a distinct, skunk-like odor. But this distinct early spring flower also distinguishes itself from all other plants native to Illinois by the fact that it generates heat--enough so that its flower can remain 36 degrees F warmer than the surrounding air for a period of about two weeks.
