Abstract
Trend data indicate that the Yellowstone grizzly bear (Ursus arctos horribilis) population has been increasing in recent years, after a decline induced by closure of open garbage dumps in 1970-71. Current population size appears to be approaching a level where management to curb further increases might be desirable, even though it will be highly controversial. Continual close monitoring is essential for managers to know how to safeguard the population. Estimating total population size of an endangered or threatened species should be secondary to measuring essential population parameters, but nonetheless may be necessary to avoid misunderstandings. Knowledge of survival and reproductive rates is essential if causes of a decline are to be detected and corrected.
