Beavers are always busy, it seems. They are very industrious and seem to never stop cutting down trees and building all kinds of neat stuff. Beavers are by far the largest rodents in North America, and a main reason that St. Louis was established here 250 years ago.

Kids ages 6-12 can learn more about the beaver, conservation efforts for them and why they are thriving in Missouri.

9:30-11 a.m. Free, but reservations are required.

At August A. Busch Memorial Conservation Area.
