In the Mosquito Lake area, regrowth has occurred and the nice stands of beech-maple woodlands can be enjoyed. In pioneer times, the beech-maple belt was very extensive and stretched from Mansfield to Pennsylvania. The reason is that this area has more cloudy days, cooler summer temperatures and more winter snow cover as compared to the rest of Ohio. The park's woodlands support colonies of spring beauties, anemones, Dutchman's breeches, purple cresses and other spring wildflowers. Goldenrod and asters will bloom in the fall in the park's open areas.
Many wildlife species find the park's varied habitats suitable.
Red fox, woodchuck, muskrat, beaver, fox squirrel, raccoon, rabbit and white-tailed deer are common. Recently, river otters were reintroduced in nearby favorable locations. Several otter families have been sighted. Many birds live in or migrate through the area including robins, warblers, swallows and sparrows. The yellow-bellied sapsucker and hairy woodpecker are uncommon in other parts of Ohio but abundant in this part of the state.
