We had a warm 80 degree day over the weekend so we decided to take a walk at the Audubon Plainsboro Preserve. The Preserve is over 1000 acres and has a 50 acre lake. Lots of trails to explore and an interesting visitor center. We had heavy rain for days so the paths & trails were very muddy but we wanted to see what we could find after a long Winter. We saw a lot of evidence of the Beavers with lots of trees showing Beaver activity. We never saw any beavers here, but they usually are busy at night so you do not expect to see them. It is amazing to see the fruits of their labor in the trees they take down. And wonder how long it actually takes them to do it. Some of the trees felled were not recent, but were probably from last year. Beavers must have strong determination along with strong teeth.
