Why are Pacific fishers rare?
Although fishers are found in many regions of northern North America, they are rare in the Pacific Northwest as a result of over-hunting for their pelts, habitat loss due to human development and logging, as well as rodenticides often used in illegal marijuana cultivation. In 2016, wildlife agencies determined that although Pacific fishers are rare, no longer occupy the full extent of their historic range, and face significant threats, they are not immediately threatened with extinction. As a result, the Pacific fisher is not listed under the Endangered Species Act.

What mammals have long, slender bodies?
Fishers are tree-dwelling mammals that have long, slender bodies, long bushy tails, and short muscular legs with large feet and retractable claws, making them climbing specialists. Fishers are very agile and have specialized hind legs with feet that turn nearly backwards, giving them the ability to climb down trees head first.
What type of trees do Pacific fish live in?
Pacific Fishers. Fishers are highly associated with older, mid-elevation (4000 to 7000 feet) forests and prefer areas with large conifer and hardwood trees, interspersed with plenty of younger trees and downed logs.
When do fish eggs start to develop?
Further, female fishers have a reproductive strategy called delayed implantation in which the eggs are fertilized during mating season between March and April, but the embryo does not begin to develop until approximately 10 months later.
Why does it need our help?
Although successful reintroductions have occurred in Olympic National Park and Washington’s central and southern cascades, this species still has a long road to recovery. Only about 4,000 fishers remain on the west coast and about 250 in the Sierra-Nevada Range. While fishers are beginning to be protected in other eastern states, Oregon and California have yet to take legal action.
Why do fish have a scent gland?

What do fishers need to survive?
Fishers require old-growth forests with an abundance of old trees, snags, and downed logs. Fishers give birth in tree cavities (hollowed out portions of a tree), and the mother will move the kits to new cavities as they grow. Fishers often use tree cavities or large branches to rest and hide during inactive periods. Aggressive logging practices do not allow forests to mature to a state that is usable by fishers as habitat.
What animal can hunt porcupines?
Fishers are one of the few animals that can hunt porcupine, flipping them on their back and attacking the belly. Fishers have a large scent gland on their feet, allowing them to leave a scent trail to communicate with other fishers. Despite being called “fishers” they very rarely eat fish.

When do fish mate?
Mating occurs in late March to early April. Females use a reproductive strategy called delayed implantation, meaning that the fertilized egg does not immediately implant in the uterus, but instead stays in a state of dormancy for ten months. In mid-February the fertilized egg is implanted in the uterine walls and active pregnancy begins. After about 50 days, females give birth in a tree cavity to one to four kits. Seven to ten days later the female is ready to mate again, and the cycle starts over once again. It is thought that female fishers choose tree cavities with openings that are too small for a male fisher to fit into, because newly-born kits are small and vulnerable during this mating period.
Why are fishers poor animals?
Fishers are poor animals to exhibit because, in general, they hide from visitors all day. Some zoos have had difficulty keeping fishers alive since they are susceptible to many diseases in captivity. Yet at least one example shows a fisher kept in captivity that lived to be 10 years old, and another living to be about 14 years old, well beyond its natural lifespan of 7 years.

Why are fisher tails so popular?

When did fishers migrate to North America?
Some evidence shows that ancestors of the fisher migrated to North America during the Pliocene era between 2.5 and 5.0 million years ago. Two extinct mustelids, Pekania palaeosinensis and P. anderssoni, have been found in eastern Asia. The first true fisher, P. diluviana, has only been found in Middle Pleistocene North America. P. diluviana is strongly indicated to be related to the Asian finds, which suggests a migration. P. pennanti has been found as early as the Late Pleistocene era, about 125,000 years ago. No major differences are seen between the Pleistocene fisher and the modern fisher. Fossil evidence indicates that the fisher's range extended farther south than it does today.

Why are fisher reintroductions successful?
Reintroductions have been successful at reestablishing fisher populations throughout much of the southern portion of their North American range, and because of this success, fisher reintroductions to the Olympic Peninsula and the Cascade Range were a prominent component of the fisher recovery plan for Washington. Reintroductions have been implemented in Washington because there appears to be sufficient habitat to support reintroduced populations. Federal, state, tribal, and private lands provide habitat for fishers in Washington and these forests are managed under a variety of approaches that can support fisher populations.
