to hybridization with wolves Males: 45-55 lbs. Females: 35 to 40 pounds Many different coat colors and patterns:

ranges: 30 square miles Nocturnal Produce 1 litter per year: 2 or 3 cubs Born and raised in a tree cavity Solitary and opportunistic predators: Snowshoe hare and porcupine RARELY EAT FISH!!

FISHER: Population Widely distributed prior to 1800’s Timber cutting and unregulated trapping

almost eliminated by 1900’s Reintroduced to Catskills, WV, PA 1994 PSU and Game Commission released

in Allegheny National Forest
