Abstract

Published and unpublished accounts of the plains pocket mouse (Perognathus flavescens) were utilized to document the existence of extant populations and to summarize and report additional data about the biology of this state endangered Iowa species. Populations of P. flavescens exist in western (Harrison, Monona, and Plymouth counties) and extreme eastern (adjacent portions of Louisa and Muscatine counties) Iowa, the latter of which represents the eastern-most record for the species in North America. In addition, we document a new locality for P. flavescens from the interior of the state (Benton County). All known populations of P. flavescens in Iowa occur in grassland habitats on well-drained substrates (i.e., loess, sandy loam, and sandy soils). Reproductive data suggested that P. flavescens in Iowa have at least two litters (early spring and late summer) of three to eight young. We hope this paper will stimulate additional research that will lead to a better understanding of the general distribution and biology of P. flavescens in Iowa.
