Fisher

The porcupine’s only real predator is the fisher. It takes a tough critter to eat a porcupine. Even coyotes, one of the state's apex predators, instinctually knows to leave porcupines alone – a trait that is sadly not shared by their domestic cousin, who rack up vet bills to have quills removed from their snouts.

Fisher populations are down, there’s consensus among wildlife biologists at least about that. But why that is happening is open to debate, as is what to do about it. 

Something Wild sat down with a couple of wildlife biologists recently who disagree; Meade Cadot, former Executive Director of the Harris Center for Conservation Education, and Patrick Tate, leader of the state’s fur-bearer project for NH Fish and Game.

Something Wild: Porcupines Aren't As Prickly As You Thought

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.
