Niobrara National Scenic River Mammals

An array of Great Plains mammals are recorded in the Niobrara Valley. Most species thrive unmanaged, though larger species such as bison and elk occur in fenced enclosures on the Fort Niobrara National Wildlife Refuge and the Niobrara Valley Preserve, which is managed by The Nature Conservancy. A free-ranging moose has also been seen on the Fort Niobrara National Wildlife Refuge, and was frequently observed by local residents this past winter. Federally endangered species like the black-footed ferret once inhabited the area, but have since been extirpated from the region. River otter, a state threatened species, is native to the Niobrara. A reintroduction program was conducted by Nebraska Game and Parks Commission biologists from 1986 to 1992, with a release site near the Sheridan-Cherry County line in northwestern Nebraska. Since then river otter sightings have occurred throughout the Niobrara Valley, including several observations in the 76-mile scenic river reach.

The scenic river is distinctive in that it supports three mammal species that are uniquely associated with the Niobrara River. Bailey's eastern woodrat, a southern species, is now found as an isolated population in the central Niobrara Valley. The olive-backed pocket mouse, a western species, is also found in the valley and occurs at the eastern limits of its range in the valley. The southern bog lemming, a rare mammal of northeastern origin, occurs within the Niobrara Valley at its interface with the Sandhills.

Bats are also documented in the Niobrara River valley and represent an important component of the biodiversity of the area. Keen's bat and the Brazilian free-tailed bat have only been found in the central Niobrara Valley in Nebraska. Keen's bat is associated with moist, eastern-type habitats, while the Brazilian free-tailed bat ordinarily has an affinity for southern, neo-tropical habitats.

When canoeing or tubing the river, visitors may also encounter white-tailed deer, raccoons, coyotes, squirrels, eastern cottontail rabbits, mink, and beaver. Hunting and trapping are popular activities in Nebraska, especially along the Niobrara River. Public land is available for hunting, but it is somewhat limited along the Niobrara. The majority of hunting and trapping occurs on private property. Individuals that wish to hunt on private property must be granted access by the landowner. If private access cannot be obtained several wildlife management areas (WMA's) are available for public use including the Borman Bridge WMA and Fred Thomas WMA. All state hunting and trapping regulations apply on public and private property.

Maine Puffins

Maine ocean islands provide the only nesting sites for Atlantic puffins in the United States. Eastern Egg Rock in the midcoast region, Seal Island and Matinicus Rock at the mouth of Penobscot Bay, and Machias Seal Island and Petit Manan Island off the downeast coast provide habitat for more than 4,000 puffins each summer.
