Home-range size and habitat used by the northern myotis (Myotis septentrionalis)

We examined home range size and habitat use of nine female northern myotis ( Myotis septentrionalis ) within an intensively managed forest in the central Appalachians of West Virginia. Using the 95% adaptive kernel method, we calculated a mean home range of 65 ha. Northern myotis used recent diameter-limit harvests and road corridors more than expected based on availability of these habitats. Intact forest stands and more open deferment harvested stands were used less than expected based on the availability of these habitats, although intact forest stands still constituted the overall majority of habitat used. Partial timber harvests that leave a relatively closed canopy appear to promote or improve northern myotis foraging habitat in heavily forested landscapes. However, the long-term ecological impacts on bats and other biota from this silviculturally unacceptable practice are unclear.

Habitat Suitability Index Models: Great egret

The great egret, also called common egret or American egret, is a large white heron tn the order Ciconiiformes, family Ardeidae. Great egrets stand 94.0-104.1 cm (37-41 inches) tall and have a wing spread to 139.7 cm (55 inches) (Terres 1980). The species is associated with streams, ponds, lakes, mud flats, swamps, ahd freshwater and salt marshes. The birds feed in shallow water on fishes, amphibians, reptiles, crustaceans and insects (Terres 1980).
