Bat Roosting Characteristics Study

A bat roosting characteristics study was initiated in 2011 to determine the roosting characteristics of western red bats (Lasiurus blossevillii) and western yellow bats (Lasiurus xanthinus) which roost in the foliage of trees as opposed to caves and mines like most bat species. Bats are captured and radio transmitters attached to them and followed back to their tree roosts the following day. Various vegetation measurements are taken at the known roost and at random non-roost sites to determine if they seek out specific areas of trees to roost in. This allows habitat creation project managers to create more specific roosting habitat for bats in the future.
