Our own Skip Lisle sends this recent article on the anxiety provoking issue of beaver digging. His central argument focuses on the demonstrable fact that beavers don’t actually waste their time or energy. Rather than riddling a bank with holes, they dig according to the most economic, practical concerns. He emphasizes sense over sensationalism, and outlines the best way to mitigate this behavior. (Hint: the answer doesn’t involve sheetpile) Go read the article, but maybe this will whet your whistle:
I would put the entire pithy treatise on the blog for you to read, but Skip has asked me to reference only the PDF so that he can keep minimal control of his writing. Go read it all the way through. It is short and concise, tells it like it is, and in my books deserves very high praise since it references the much bandied-about-term “swiss cheese” without being at all sarcastic.
For the record, beaver tunnels do not look anything like this.
