Vermette pointed out where beavers had built a dam across one of the waterways, thus raising the water level behind it significantly. In many areas beavers can be problem animals, but here their dam slows the water flow still more, thus enhancing the marsh’s role in improving water quality.
Considering the bitter smack much of New York has been happy to talk about beavers, this article is a breath of fresh air. It describes two graduate students charged with monitoring, testing and studying the area, and who have been particularly enthusiastic about the effect of the resident beaver dam. The article goes on to describe how beavers often cause problems and dams are routinely destroyed by the transportation department, but how these students petitioned to let these particular beaver stay and help the polluted waters. Guess how well its working? The bemused article makes it sound like this healing dam is something unique or special, and sadly doesn’t mention that beavers could be bestowing the same gifts everywhere if they were just allowed to live. I wrote them the following:
Gerry Riser’s charming piece about the beaver dam improving water quality in Woodlawn wetlands seems to suggest that the good work done by this helpful dam is the exception rather than the rule. The truth is that once the transportation department stops wasting taxpayer dollars on futile dam removal and invests instead in real solutions like flow devices and culvert fences, every waterway, stream and creekside can be significantly improved by the addition of beavers. The secret wetlands of Woodlawn are only rare in their appreciative scholars: beavers benefit any waterway that is lucky enough to have them.
I heard from Sharon of Beavers: Wetlands & Wildlife that they did a consult for a flow device in the area as well, so Buffalo should know better than to think ripping out dams is the solution.

On a entirely different note I saw amazing footage taken by Moses yesterday morning of a MASSIVE otter in the area between the dams. His long whiskers and huge size let us know this is an otter that has seen many, many summers. Moses wasn’t willing to share the footage with the website, but keep your eyes peeled. We didn’t see sign of him last night, or the beavers either for a good long time and I was starting to get nervous. The kits eventually emerged as cheerful as you please, GQ crossed delightfully over the dam, a muskrat swam by and three green herons flew in for a squabble on the filter. All in all, it’s a pretty healthy habitat. Hear that Buffalo?
