Woodland Voles Captured Among Sparse Shrubs in Native Tallgrass Prairie on Konza Prairie Biological Station, Kansas

Abstract

From autumn 1981 through spring 2009, woodland voles (Microtus pinetorum) were captured rarely and only in woodland habitats (four in ca. 15,000 trap nights) and never in grassland habitats (ca. 300,000 trap nights) on the Konza Prairie Biological Station, Kansas. Konza Prairie is located in the Flint Hills region of eastern Kansas in Geary and Riley counties (see Knapp and Seastedt 1998 or http://keep.konza.ksu.edu/visit/map. htm for maps and location). We summarized characteristics of these voles (all four voles captured in moist gallery forest; Kaufman and Kaufman 2009) as well as their locations and habitat features because small mammals only were to be sampled in grassland sites away from gallery forest habitats as we completed our long-term studies of small mammals during autumn 2009 through spring 2013 (nearly 30,000 more trap nights during this time period). Unexpectedly, two woodland voles were captured in a prairie site during March 2013, which was the last sampling period of our 32 year study. Herein, we describe the characteristics of the two voles captured along a prairie trapline plus features of the habitat surrounding capture locations.
