This first dam has created a small pond that is about five meters below the level of Witch Hole Pond. If this dam had not been constructed this area would just be a stream like the one we saw a moment-ago with our hero. By damming up this stream and creating this pond the beaver has created a safe habitat for itself to either travel farther down stream or build a future lodge in. Here is just one example of beaver activity. Beavers do not only use trees and twigs for construction, but they also use it for their main source of food.
Beavers eat the inner bark of trees, that is called the cambium layer.
To eat they first strip the outer bark, than they go to town just like we would eat a piece of corn on the cob. It is hard to digest but their digestive tracts are well adapted to extracting the little nutrients within the wood. This dam has made a small swamp just below Which Hole Pond where many water tolerant plans grow up above the surface, and beaver trails can be seen through the water. In The Water PPT Slide Hiking up farther along the edge of the swampy area our hero begins to find thousands of beaver markings, he must be very careful now. Despite the danger our hero measures each tree s diameter, height to cut, and if possible the tree type.
