LAUSR

Abstract Cryptotis parva (Least Shrew) is an insectivore that is widely distributed across peninsular Florida but has only twice been captured in the Florida Keys, both times on the island of Key Largo, Monroe County. To preliminarily evaluate the presence of Least Shrews, we installed drift fence arrays (cross design) in January and December 2013 at locations near areas with previous observations on North Key Largo. We sampled 4318 trap-nights, with 1276 trap-nights in the first session and 3042 in the second session. In total, we captured 3 individuals at 2 of 3 drift fences. Including our 3 individuals, only 5 Least Shrews have been captured on Key Largo. A more comprehensive effort to survey for shrews across Key Largo and compile unpublished records is needed to determine the species distribution.
