Some readers have reported an unfamiliar, dark and furry creature in the woods. Odds are high it蘑菇视频 not Bigfoot, but those readers may have spotted a fisher. That many people don鈥檛 recognize a fisher is no surprise. Fishers became extinct in this region more than a century ago. Fishers need forest, and when settlers felled the native forest across the Alleghenies, fishers and other woodland-dependent wildlife disappeared. Today they鈥檙e back, but not without help.

The fisher is closely related to the mink, skunk, weasel and otter. It is weasel-like in appearance but larger, about like a fox, cloaked in brown to black fur, sometimes brindled with white or silver. Big males can exceed four feet from snout to tail-tip, with the furry tail accounting for about a third of the total length. The triangular head is topped with short rounded ears. Adult males generally range between nine and 12 pounds, but the largest can double that. Females are smaller.

Fishers never disappeared from forested regions across Canada, and as second-growth woodland reclaimed the American landscape, biologists in West Virginia, New York, Michigan and Wisconsin sought to re-establish fishers in those states. Pennsylvania followed with its own reintroduction effort soon after, but no fishers were released in this region. Fishers seen in Fayette, Somerset and neighboring counties are believed to be from expanding populations in West Virginia.

The Pennsylvania Game Commission蘑菇视频 Fisher Management Plan states that West Virginia released fishers captured in New Hampshire as early as 1969. New York followed in the 1980s by re-locating fishers from a remnant Adirondack population to other forested tracts. Between 1994 and 1998, Game Commission biologists working cooperatively with Frostburg University released 190 fishers at six sites across northern Pennsylvania.

鈥淔isher reintroductions have been a success across the Northeast and Midwest, maybe at a quicker rate than we expected,鈥� said Matt Lovallo, wildlife biologist in the Pennsylvania Game Commission蘑菇视频 Game Mammals Section. 鈥淎lthough we released fishers in northern Pennsylvania, and they鈥檙e doing well, we believe the growing population in southwestern counties is a result of range expansion from West Virginia.鈥�

Fishers are active, opportunistic predators of diverse prey. Small rodents, rabbits, squirrels and carrion make up much of the menu, and fishers are effective predators of porcupines where that prey is available. But biologists concede it will eat almost any wild creature that doesn鈥檛 eat it first.

鈥淚n fishers, we鈥檝e seen the most diverse diet, including each other, of all forest predators; there蘑菇视频 nothing they won鈥檛 eat,鈥� Lovallo said.

Biologists have even found deer remains in fishers and fisher droppings but it蘑菇视频 unclear if fishers prey on live deer or take advantage of deer they find dead in the woods or along roads.

鈥淲ith some food items like deer, whether its predation or scavenging, we don鈥檛 know,鈥� Lovallo continued. 鈥淲e do understand that hunters have an intuitive concern about turkeys because fishers are skilled tree climbers, but birds are very limited among the food items we鈥檝e analyzed.鈥�

Biologists know that fisher populations are growing and spreading because they monitor legal trapping harvests, survey trappers to track incidental fisher captures and document road-kills.

The Fisher Management Plan reports that between 2001 and 2008 the number of fishers trapped incidentally rose from one to 105. The Game Commission蘑菇视频 Wildlife Management Unit 2C comprising mountainous parts of Fayette, Westmoreland, Somerset, Indiana and Cambria counties accounted for nearly half of the 2008 state total.

鈥淪ince we wrote that plan in 2008 the number of incidental captures has climbed to over 1,000 today,鈥� Lovallo said.

Lovallo explained that incidental captures are fishers caught unintentionally by trappers targeting other species such as fox or raccoon, or trapped outside units open to legal fisher trapping. Trappers are required to release these fishers unharmed if possible.

Since 2010 the Game Commission has regulated a limited trapping season for fishers across 13 wildlife management units including WMUs 1B, 2C (includes eastern Fayette County) and 2D in western Pennsylvania. Only one fisher may be taken per year and trappers must have a fisher permit.

Jim Griffith, a veteran trapper from Somerset who also works as a fur receiving agent for Fur Harvesters Auction, Inc. of North Bay, Ontario has caught fisher in wide-ranging locations.

鈥淚 travel a lot buying fur and I trap in a lot of places,鈥� Griffith said. 鈥淏eing an aggressive predator, fishers are fairly easy to trap. When the Canadians trap beaver in the remote bush they skin them on-site and take just the pelt. If a fisher gets on that beaver carcass it won鈥檛 leave it, even if it has to fight wolves.鈥�

Griffith said renewed interest in American fur from Chinese and Russian buyers is encouraging news for local trappers and the fur market, fisher pelts included.

鈥淚鈥檓 optimistic and fur prices can only go up from here,鈥� Griffith observed. 鈥淣ot long ago a prime female fisher brought $200. Today, maybe $60 or $70.鈥�

Female pelts fetch better prices than male fishers because the female蘑菇视频 fur is softer and silkier. Griffith said fishers are unique in that regard.

鈥淎round here, you mainly find fisher in heavy woods with hemlock or spruce, where they can get red squirrels,鈥� Griffith said. 鈥淏ut they have adapted well to all kinds of woodland and all types of prey.鈥�

When asked to explain biologists鈥� motivation in reintroducing an efficient predator like the fisher, Lovallo doesn鈥檛 hesitate.

鈥淭he reality is that we had fishers prior to the 1900s. Part of our agency [Game Commission] mission is to restore wildlife populations,鈥� Lovallo reflected. 鈥淲e鈥檝e restored many such as elk, otter, eagle and beaver. Other large predators like wolves and mountain lions we鈥檝e lost and probably never will get back, unless they do it on their own.鈥�
