Indiana Bats are creatures of habit and tend to return to the same hibernacula each year, and their species is found in Maryland, Virginia, and West Virginia amongst other states in the US. Their decline is due to many reasons. Vandalism and human disturbance of their hibernacula have taken a terrible toll on their numbers, but add to that the degradation of their summer habitat - from forest clearing, stream channeling, housing developments, and the clearing of land for agriculture - and the future survival of this small flying mammal hangs by a thread.
