Last winter (2009-2010), a beaver spent the season at the FWG Amphibian Pond. That beaver left in the spring when its dam kept getting broken, and no doubt prompted by lack of food. A month or more later, another beaver stayed briefly in the pond, and then with fall came the visits of at least two beaver, one stayed briefly, but the other has started to build a dam. We wonder what will happen this time. There is now a new, raised bridge, so a dam won't impact (or shouldn't) on the bridge. On the other hand, there is not a lot of food, and we notice that the beaver has gone some distance from the pond to gnaw down a few poplar.
