ABSTRACT: Bats are critical ecosystem service providers throughout the United States. However, their habitat use in the states of the plains is widely unknown.  The goal of our work is to determine the scale at which we can predict the habitat use of bats and hopefully, in turn, narrow the preexisting gap of knowledge.  By comparing both the scale of remote census data with site measurements within 50m of a stationary point we are able to determine if time consuming and expensive habitat sampling is required for determining the location of bat foraging habitat.  We are conducting an acoustic survey throughout of the state of Nebraska using 2-4 stationary points located in 10 km by 10 km grid cells selected using a Generalized Random Tessellation Stratified (GRTS) sampling method.  A total of 126 deployments of detectors were completed in 9 different habitat types and 35 grid cells. Through both on the ground site measurements and GIS layer assessments logistic regression models were produced to predict what habitats each species of bat in Nebraska is utilizing.  Our results will determine if a more cost effective method that involves less strenuous site measurements and that is less of a burden on land managers can be created.
