Fisher

About

How fisher lives

Fishers are forest mustelids that hunt, scavenge, and climb through North American woodlands. Fishers are one of the few predators able to regularly attack porcupines. Forest habitats reward animals that can climb, hide, or move quietly through layered vegetation.

Conservation

Status and habitat pressure

Stable populations still depend on habitat quality, food availability, and low human pressure. Protecting fisher also depends on keeping forest habitats healthy and connected.

Common species still depend on habitat quality, clean water, food webs, and low disturbance.
