We’ve been hearing a lot about porcupines this year. They seem to be everywhere! It’s positively a plague of porcupines! So why are there so many? Biologists don’t have an official answer, but Dave Anderson has a hypothesis involving coyotes and fisher cats. The porcupine’s only real predator is the fisher. It takes a tough critter to eat a porcupine. Anecdotally, trackers and hunters are reporting that fisher numbers appear to be down this year, so it makes sense that porcupine numbers are up.
