Huckleberry Habitat and Its Influence on Two Small Populations of Grizzly Bears (<i>Ursus arctos</i>).

ABSTRACT: Huckleberries (Vaccinium spp.) are a nutritionally important food to grizzly bears (Ursus arctos) in interior, western North America. They provide sugar-rich calories in late summer and fall prior to denning. We developed a resource selection function of high-quality huckleberry habitat important to Cabinet-Yaak and Selkirk female grizzly bears using field-verified huckleberry foraging radiolocations acquired during prime months of huckleberry fruiting (July 15-September 15, 2010-2019, n = 22). Logistic regression analysis identified a model with 12 significant variables in predicting huckleberry habitat important to female grizzly bears (Somers' D = 0.729; K-S statistic = 0.570, p < 0.00001). Most influential variables (p < 0.00001; positive [+] or negat
