Red squirrels are conifer specialists, holding tight territories around a central cache of cones called a midden, and Ohio’s mostly deciduous forest gives them far less of that habitat than the pine and hemlock stands farther north. Cuyahoga Valley National Park is the only named site with a real report tally, likely tied to the scattered conifer plantings along its river corridor, but wooded river valleys and state parks elsewhere in the state can hold pockets of the same cover.

Reports build through spring, peaking in May with April and June close behind, a stretch that lines up with the end of the mating chase and the raising of a spring litter, when a normally solitary, noisy defender of its territory is easier to hear and spot. A single-digit named-place tally isn’t enough to call any one site a hotspot, only a real one.
