Cuyahoga Valley National Park Biologist, Meg Plona, says five young (and 2 adults) were first observed in the Beaver Marsh in 2013. Beavers created the marsh after the Portage Trail Group of the Sierra Club helped clean up an auto junk yard formerly located at that site in 1984. "We don't know exactly where the adult pair at Beaver Marsh came from" says Plona "Having made a great comeback they were de-listed as a state endangered species in 2002 and presently occur throughout eastern Ohio, including their return to CVNP."
When asked about the status of the adult pair's offspring Plona added "We don't know where the offspring are or what they are up to, as they are not marked animals - young otters are self-sufficient by the time they are 5 to 6 months old, but the family group remains intact for at least 7 or 8 months or until just prior to a new litter. Yearling otters can disperse up to 20 miles or more from where they were reared." Plona says the river otters are protected like all native mammals in the park, 'however there are no "special" protections or management strategies in place for the otters at this time."
Plona notes there are optimal times to see the otters "River otter sightings at the Beaver Marsh usually occur in the very early morning when there is minimal human disturbance. In general, these mammals are also very active at dusk and throughout the night feeding on fish."
Want to marvel at the Cuyahoga River Valley's comeback? Take a trip to the Cuyahoga Valley National Park and go see the river otters for yourself! Once you do, perhaps you'll consider sponsoring a Beaver Marsh acre via the Conservancy for Cuyahoga Valley National Park!
