Quick Take
- The return of the fisher to Ohio marks the first verified sighting in Cleveland Metroparks and the first in Cuyahoga County in roughly 200 years.
- Fisher habitat depends on large, connected forests with dense cover, fallen logs, and hollow trees.
- Read on to discover which forest connectivity changes will determine how far Ohio’s fisher expansion reaches.
In 2025, a motion-triggered camera quietly watching a forest corridor in Cleveland Metroparks captured something unexpected. A dark-furred predator moved through the leaf litter, paused, and looked directly into the lens. The animal was a fisher, a forest carnivore that had not been confirmed in Ohio since the nineteenth century. The sighting in Cuyahoga County marked more than an unusual wildlife moment. It reflected decades of forest recovery, improved land management, and careful conservation work across the region.
What Are Fishers?
A fisher is a medium-sized carnivorous mammal native to North America that looks a bit like an extra-long mink with dark brown fur and a bushy tail. Despite the name, it does not fish for food. Instead, it lives in forests and hunts small animals like rabbits, squirrels, birds, and rodents, and it is famous for being one of the few predators capable of killing porcupines by repeatedly attacking the face and flipping them onto their unprotected belly.
Fishers are excellent climbers and fast, agile hunters, spending much of their time in trees or moving stealthily along the forest floor. They are solitary, elusive animals, rarely seen by people, and play an important role in keeping forest ecosystems balanced by controlling populations of their prey.
A Species with a Wide Range
Fishers occupy a broad range across North America. They live in southern Canada, including the boreal forests, and extend into the northern United States. Populations exist in New England, the Great Lakes region, and parts of the Pacific Northwest.
Fishers are closely tied to large blocks of forest, especially those with a mix of hardwood and coniferous trees. They depend on dense cover, fallen logs, and hollow trees for shelter and denning. These features are most common in older forests that have been allowed to grow without heavy cutting.
