Abstract
Until recently, little attention has been directed to the bat fauna of GTNP. The role of bats in ecosystems is more significant than previously thought. Also, the public's awareness of bats is growing and as part of routine interpretive needs, the NPS must have factual information on all animals in the Park. A baseline survey was conducted to determine species composition, distribution, abundance, and habitat use of bats in Grand Teton National Park, Wyoming. The principal objectives are: 1. Obtain information on species occurrence and distribution within the Park; 2. Assess the population status for bat species present; 3. Identify rare species in the Park and identify management needs to ensure the viability of these species in GTNP; and 4. Evaluate potential conflicts with human activities.
