Evidence of Beavers

We have evidence of a beaver's handiwork close to the Old Plank Bridge!

As you approach the arching, wooden bridge from the Lower Grove picnic area, look to your left, along the riverbank, for a tree with a light colored base.

The bark is gone exposing the lighter colored layers of wood inside the tree.

A close inspection will clearly show the chew marks, from the beavers strong, and large, front teeth. The ground will also be littered with "beaver chips", or wood chips.

We have not seen the beaver working (they are nocturnal) but first noticed it's progress on Nov. 28, 2017 - Photo 1.

By Dec 1 more of the tree trunk was chewed off - Photo 2.

It has remained the same way for a couple of weeks now - see photo 3.

Beavers chew trees for food, to build dams and construct their homes, or lodges. This tree should topple into the water if the beaver keeps chewing!

Although beavers have lived here for many years, this is the first time, since the nature center opened, that we've seen beaver activity north of the river, (the West Branch of the DuPage River).

We've seen evidence of beavers south of the West Branch for awhile now.

Here's a photo of a felled tree that's very close to the confluence.

Unfortunately for the beaver, it didn't fall into the water! It fell onto the trail instead. But we notified our Park staff so they could clear the path.

Beavers create habitat for a variety of animals and provide places for flood waters to slowly recede.
