“Nothing is more priceless and more worthy of preservation than the rich array of animal life with which our country has been blessed,” President Richard Nixon once said when signing the Endangered Species Act. That sentiment resonates deeply in Ohio this winter, where a silent shadow of the forest has stepped back into view after nearly 200 years.
A wildlife camera in the middle of Cleveland Metroparks early this year caught the indisputable shape of a fisher, a quick wood-dwelling carnivore of the weasel family, padding through the litter of leaves under a cover of bare trees. The video, which was later verified by Cleveland Metroparks wildlife management coordinator Andy Burmesch, was the first verified observation of the species in Cuyahoga County since the 1800s. It is a historic and a hopeful moment to the ecologists and nature lovers.
The extinction of the fisher in Ohio was caused by two interacting forces, the uncontrolled harvest of its valuable fur and the loss of the mature forest habitat nationwide in the 19 th century. Towards the middle of the nineteenth century, the animal had been regarded as extirpated in the state. Its recurrence is not a coincidence. The officials of the wild life cite decades of purposeful reintroduction efforts in adjacent Pennsylvania and West Virginia where transplanted fishermen created breeding stocks that have since grown to the west. Regulated trapping seasons are in both states which is an indicator of sustainable recovery.
The comeback is picking up in Ohio. The Ohio Department of Natural Resources (ODNR) has verified over 40 fisher sightings in the counties of northeast and about 2/3 rds of these are within the last three years. Part of these documents provide strong grounds of permanent stay as opposed to temporary visits. In 2023, one of the fisher spotted on a road in Ashtabula County was discovered to be pregnant. Another was hit in Portage County near Kent in April 2024, the heaviest on record in Ohio, and the last to be seen in the west.
Although fisher cat is a misleading name since the animal is not a cat, it is not anything to with fish. They belong to the mustelid family, which is related to martens, mink and otters; they are long, low bodied, have a bushy tail, tapered muzzle and rounded ears. Adults have 20 and 25 inches body length and the tails have 13 and 16.5 inches. They have a diverse diet and feed on rodents, squirrels and birds; they also love fruits and nuts. Fishermen, unlike the smaller mink usually 12 to 16 inches in length, with a white patch on his chin are adapted to both terrestrial and aerial pursuits, and can easily make his way through a thick forest.
The sighting of Cleveland highlights the value of well-preserved habitats. Fishers are found in extensive areas of forests where the tree canopy is also mature and in many cases the tree cavity is used to nest. These landscapes are also closely associated with good wetlands and waterways which, as the U.S Environmental Protection Agency points out, come as biological supermarkets to underpin complicated food webs. Wetlands are not only a source of prey to fishers but also they protect the ecological integrity of the forests where they live in.
Contemporary conservation technologies have been central to such a rediscovery. Trail cameras, which were initially a niche research technique, have become large networks of cameras that silently track animals in remote places. Such camera grids have demonstrated migration patterns, causes of death and favorite habitats of fishers in places such as New Hampshire and Connecticut, which have such camera grids coupled with GPS collaring. The information is used to inform decisions within the management, such as the trapping season modifications, or the key areas on highway crossings.
The recent overcoming of Ohio by the fisher is adding to a list of native species that are returning to their places in the ecosystem, including river otters, bobcats, and trumpeter swans. Every time it reemerges, it is a reaffirmation that extirpation is not forever with perseverance, science and popular will. It creates a tincture of wildness in familiar scenes, to the locals, who now know that such a mysterious predator was once again roaming through the wooded ravines of Cleveland. And to conservationists, it is a living legacy to the importance of conservation of forests, wetlands, and waterways, not just to the species that rely on these resources, but also to the heritage of their conservation.
