Metadata (Data about data or how the map was made)

One of the most versatile of all bats, the Big Brown Bat is found in all 48 continental states though it is more abundant in hardwood forests than in coniferous forests. In Washington it has been found in every area surveyed although it is less common in alpine zones and perhaps in steppe zones. It can fly long distances from water to forage and it uses human structures readily, even in urban areas. It hunts in a variety of situations, including over water, forest canopies, roads, clearings, and urban areas.

All zones were core, except Alpine/Parkland which was peripheral. All habitats in forested zones and Alpine/Parkland were good except unvegetated. In the steppe zones, all habitats were good, except that dryland agricultural, sparse vegetation, grassland, and shrub savanna were adequate.
