However, there was active sign this summer in another part of the same stream not too far from this property, and I remain hopeful for another try by some more beaver soon.
Did the nearby beavers stick around?
purposefully pursuing the perfect perennial permaculture answer: It Depends
After a couple of years of no beaver activity in my ravines, this year there are again a couple of low trashy dams. Nothing fancy, just the kind of nudged-up green sticks and muddy schmutz that a young beaver makes so that he can swim around instead of clambering over the rocks in a stream that's too shallow. Having had my hopes dashed now several times in the past, I am not investing too much anticipation in this round of activity. But each time this has happened in the past, the result has been a fairly considerable increase in sediment in the ravine in the area of beaver activity, with a widening of the notch, a shallowing of the angle of the banks, and an increase of bank vegetation after the beavers have moved on. So it's all good.
That's great news!
Last summer on a visit to my mother in rural NJ I went kayaking on a lake where the ranger told me a beaver lodge had been spotted. I found the lodge and went poking around nearby, then suddenly next to me was this massive KERPLUNK depth charge and a head that looked to me like a sopping wet irish setter (it was that big) went swimming by, grinning. Scared me so good I nearly tipped the kayak, but was probably the best thing i saw in 2018!
Marco, there may be one juvenile maintaining some low berms of mud and leaves, just four to six inches high, enough to allow easier travel up and down the stream. But if so, he's not feeding on my side, not in the last several months. It does however seem that the berms wash out with every rain and get rebuilt with fresh mud and greenery.
