Tracks in the snow, hair on a fence, loud cries in the night. Could it be a mountain lion? The mountain lion and other large carnivores once served as nature's check on deer and other prey species. Today, humans control the deer herd, so the natural role of this big cat is gone. There aren't many animals that receive more interest in Missouri than mountain lions.
Ages 12 and up are invited to hear what experts have to say about the mountain lion in Missouri and the many misconceptions that surround it. You'll also hear about current research methods to study mountain lions in Missouri.
Free. 7 p.m.
At Powder Valley Conservation Nature Center in Kirkwood, near the intersection of I-44 and I-270.
