Return of the fisher: Once extinct in region, fisher on prowl again
Some readers have reported an unfamiliar, dark and furry creature in the woods. Odds are high it无毛视频檚 not Bigfoot, but those readers may have spotted a fisher. That many people don无毛视频檛 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无毛视频檙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无毛视频檚 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.
无毛视频淔isher reintroductions have been a success across the Northeast and Midwest, maybe at a quicker rate than we expected,无毛视频� said Matt Lovallo, wildlife biologist in the Pennsylvania Game Commission无毛视频檚 Game Mammals Section. 无毛视频淎lthough we released fishers in northern Pennsylvania, and they无毛视频檙e doing well, we believe the growing population in southwestern counties is a result of range expansion from West Virginia.无毛视频�
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无毛视频檛 eat it first.
无毛视频淚n fishers, we无毛视频檝e seen the most diverse diet, including each other, of all forest predators; there无毛视频檚 nothing they won无毛视频檛 eat,无毛视频� Lovallo said.
Biologists have even found deer remains in fishers and fisher droppings but it无毛视频檚 unclear if fishers prey on live deer or take advantage of deer they find dead in the woods or along roads.
无毛视频淲ith some food items like deer, whether its predation or scavenging, we don无毛视频檛 know,无毛视频� Lovallo continued. 无毛视频淲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无毛视频檝e analyzed.无毛视频�
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无毛视频檚 Wildlife Management Unit 2C comprising mountainous parts of Fayette, Westmoreland, Somerset, Indiana and Cambria counties accounted for nearly half of the 2008 state total.
无毛视频淪ince we wrote that plan in 2008 the number of incidental captures has climbed to over 1,000 today,无毛视频� 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.
无毛视频淚 travel a lot buying fur and I trap in a lot of places,无毛视频� Griffith said. 无毛视频淏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无毛视频檛 leave it, even if it has to fight wolves.无毛视频�
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.
无毛视频淚无毛视频檓 optimistic and fur prices can only go up from here,无毛视频� Griffith observed. 无毛视频淣ot long ago a prime female fisher brought $200. Today, maybe $60 or $70.无毛视频�
Female pelts fetch better prices than male fishers because the female无毛视频檚 fur is softer and silkier. Griffith said fishers are unique in that regard.
无毛视频淎round here, you mainly find fisher in heavy woods with hemlock or spruce, where they can get red squirrels,无毛视频� Griffith said. 无毛视频淏ut they have adapted well to all kinds of woodland and all types of prey.无毛视频�
When asked to explain biologists无毛视频� motivation in reintroducing an efficient predator like the fisher, Lovallo doesn无毛视频檛 hesitate.
无毛视频淭he reality is that we had fishers prior to the 1900s. Part of our agency [Game Commission] mission is to restore wildlife populations,无毛视频� Lovallo reflected. 无毛视频淲e无毛视频檝e restored many such as elk, otter, eagle and beaver. Other large predators like wolves and mountain lions we无毛视频檝e lost and probably never will get back, unless they do it on their own.无毛视频�
