The refuge's landscape is varied, with rolling hills, large ledge outcrops, streams, lakes, bogs, and marshes. A northern hardwood forest of aspen, maple, birch, spruce and fir dominates the upland. Scattered stands of majestic white pine are common. The Edmunds Division boasts several miles of rocky shoreline where tidal fluctuations of up to 24 feet occur twice a day.
This habitat diversity supports many wildlife species. The staff at Moosehorn National Wildlife Refuge (NWR) manages the land to protect the Service's ""trust resources"". which include migratory birds, endangered species, and wetlands. By improving habitat, the Service ensures that wildlife will thrive on the refuge.
Woodcock, ruffed grouse, moose, deer, and a variety of songbirds prosper only in a young forest. In the past, wildfires revitalized the forest, while farming maintained open areas. However, wildfire is a rare event today, and farmland acreage has decreased dramatically. Habitat management programs, including timber harvesting and controlled burning, mimic the effects of wildfire and farming by providing clearings an d early growth forests.
Approximately one third of the refuge is designated as federal wilderness. The two Wilderness Areas (one in each division) are part of the National Wilderness Preservation System. They are managed with a "hands-off" philosophy and granted special protection to maintain their primitive qualities. Internal combustion engines and mechanical means of transportation (i.e. bicycles) are not allowed. Habitat management is kept to a minimum to allow the areas to develop into old- growth climax forests.
Bald eagles, frequent both divisions of the refuge, feeding on fish in the streams, ponds, and flowages. In recent years, as many as three pairs of eagles have nested at Moosehorn NWR. Eagles are frequently sighted around Magurrewock Marsh on the Baring Division and along the shore of Dennys Bay on the Edmunds Division. Osprey nest in several of the refuge marshes with as many as four pairs using platforms along the Charlotte Road.
The woodlands of Moosehorn NWR are home to many songbirds, including neotropical migrants, species that breed in North America and winter in Mexico, the Caribbean, and Central and South America. In mid-May, migrating warblers fills the forest with song. Twenty-six species of these diminutive birds nest on the refuge. In addition, northern forest species, such as boreal chickadees and spruce grouse, are present.
