The
high probability of a recent fisher sighting in Northeast Ohio may
prove an indicators of the species’ natural recovery back into the
region.
Several
weeks ago a trail camera set up along the East Branch of the Chagrin
River in Lake County captured the image of what’s believed to be a
fisher.
The trail camera was set up on private land near the massive
Holden Arboretum, which is established in Lake County’s Kirtland
City, Kirtland Hills Village, and Geauga County’s Chardon Township.
Due
to the Arboretum and the area’s extensive large wooded home sites,
the general area is much less developed than surrounding
neighborhoods.
Perhaps
not surprisingly it is also the same remote and rugged river corridor
frequented by black bears – typically young males – being
dispersed. This, following expulsion by their mothers from their
haunts in northwest Pennsylvania.
And
biologists with both the Ohio Division of Wildlife and the
Pennsylvania Game Commission believe that fishers are experiencing
the same expansive strategy.
Fishers
were lost to Ohio sometime during the mid-1800s; the great
extirpation period that saw wolves, black bears, elk and other
species disappear from the state.
While
the wild turkey, white-tailed deer, river and otters and others have
returned either naturally or with human reintroduction efforts, some
species are doing so at a much slower rate. Among them are black
bears and fishers; a large member of the weasel family that can
weight up to 13 pounds with males and up to six pounds with females.
Officially
in Ohio, fishers are listed as both “extirpated” (meaning having
disappeared from a particular part of their range) as well as a
“species of special interest.”
By Ohio law, they cannot be
trapped and if caught, they must be released.
Yet
it appears back to Ohio the fishers will almost certainly come to
stay, biologists are speculating.
“It
does and it does not surprise me,” said Katie Dennison, the
Wildlife Division’s fur-bearer biologist on the likely recent
fisher sighting in Lake County.
To
illustrate the infrequency of fisher sightings in Ohio, Dennison said
since 2013 the Wildlife Division has confirmed only eight of them.
“But
five of those have occurred within the past two years, including one
sighting by our wildlife officer in Ashtabula County,” Dennison
said.
In
fact, of the eight sightings, one-half happened last year, with all
but one occuring in Ashtabula County.
Which
most certainly does not shock Dennison. Nor does it particularly
startle Aaron Facka, Dennison’s counterpart with the Pennsylvania
Game Commission.
“Ten
years ago our fisher population was centered in the north-central
part of the state, and around the Allegheny National Forest. Now
they’re everywhere in Pennsylvania except for the urban areas of
Philadelphia and Pittsburgh,” Facka said.
That
expansion includes what the Game Commission designates as its
Wildlife Management Unit 1B, consisting primarily of Pennsylvania's
Crawford County, which is Ashtabula County’s nextdoor neighbor.
And
while in 2019 about 700 fishers were recorded as being legally
trapped in all of Pennsylvania, fully 150 of these animals were taken
in Unit 1B, also said Facka.
“Expansion
took off after 2004 but has slowed some since,” Facka said.
Both
Facka and Dennison believe that what is happening in Northeast Ohio
is that natural dispersal of young males striking out on their own
and looking to stake a claim elsewhere.
Strong
evidence of that belief is partly rooted in knowing that the two
roadkill fishers collected since 2013 and examined by the Wildlife
Division were both young males, Dennison said.
Both
fur-bearer biologists say too that the habitat and available prey
base – which includes squirrels, rabbits and birds besides
porcupines which are vacant from Ohio – exists in sufficient
quantities to attract dispersed fishers.
“If
all you have are young males and the females are back in
Pennsylvania, the males will go back there to mate but will return to
where they were,” Facka also said.
Meaning,
Northeast Ohio.
“I
suspect you’ll see a breeding population sooner or later,” Facka
said as well.
All
of which excites Dennison, knowing that after a nearly 200-year
absence Ohio might very well provide a homecoming for the shy and
reclusive fisher.
“We
are asking the public that if they do have a fisher sighting to
report it to our wildohio.com web site,” Dennison said. “If we
start to receive more reported sightings than we can do more research
and possibly even conduct a reintroduction program.”
