摘要：

We estimated the effect of thinning ponderosa pines (Pinus ponderosa) on populations of Abert's squirrels (Sciurus aberti). In 2008 and 2009, thinned and unthinned stands of ponderosa pines were sampled for evidence of over-winter feeding activity. Density of Abert's squirrels decreased from 2008 to 2009. In 2008, evidence of feeding was on 25 of 27 stands with no difference in density of Abert's squirrels between thinned and unthinned stands. Evidence of feeding was much lower in 2009, with 13 of 32 stands showing no evidence of feeding.
