We also examined whether grizzlies increased their fall movement rates, predicting that if seeds were a highly preferred food, the reduction in live whitebark pine would require bears to exploit more dispersed and distant stands over time. Increased movements, associated with low production, have been observed among several black bear populations where acorns are considered a fall staple. Among grizzly bears that had whitebark habitat in their fall range, we detected no change in movement rates over the study period. On average, bears did not roam over larger areas or search more within their fall range. We concluded that bears were consuming alternate foods within the area of their fall range. Thus, our results are more consistent with the idea that whitebark seeds are consumed opportunistically as part of a diverse diet, rather than a highly preferred fall staple.
