This study compares parameters for Great Basin Pocket Mice residing near radioactive waste disposal sites and within a nearby protected (control) area. Mice emerged from below ground torpor in early spring (Mrch), with males appearing earlier than females. Young-of-the-year first appeared in significant numbers during June. The ratio of males to females approximated 1:1, except during early spring months. Estimates of seasonal abundance showed peaks of 47 and 42 pocket mice per ha for disposal and control study areas, respectively. An estimate of pocket mouse biomass (g live weight) revealed peaks of 541 g/ha and 683 g/ha for disposal and control areas. The proportions of reproductively active males and females were equivalent on both study areas.
