This study was done in Carlsbad Caverns National Park on Mexican free-tailed bats during 1996. The main objectives were to develop a monitoring technique that would: provide a consistent estimate of the minimum population size; provide a measure of statistical precision so that annual trends could be compared; be user-friendly so that revolving park staff, with variable levels of expertise, could collect consistent data; be relatively inexpensive so that monitoring could be done annually; and have the potential for being comparable with data collected elsewhere so that immigration and emigration, as well as regional trends, could be assessed.
