Today, at least in our little corner of the universe, we can claim victory: no dam, no beavers, no flooding. I don't know how it happened or where they went, but I do know for a fact that the neighbors who broke the dam didn't move the sticks nearly far enough away from the stream. So, when the beavers return--and they will, though, again, I don't know how--they will have ample ammunition for their new assault.
I mention this because today, the New York Times highlighted the explosion of the Massachusetts beaver here. As one expert said, "There are at least 30,000 beavers all over the state. . .[each of] which can reach 60 pounds and are the largest rodents in North America. . .Beavers are the ultimate ecosystems engineers."
My response: A large, pervasive, tenacious, industrious ecoengineer rodent is, to paraphrase Groucho Marx, still a rodent.
Now that they've made the New York Times, I'll let you know when their national tour reaches our neighborhood again.
