- Westslope cutthroat trout Oncorhynchus clarki lewisi now occupy less than 5% of the subspecies' historical range within the upper Missouri River drainage in Montana. We assessed the risk of extinction for 144 known populations inhabiting streams within federally managed lands in the upper Missouri River basin using a Bayesian viability assessment procedure that estimates probability of persistence based on subjective evaluation of population survival and reproductive rates as influenced by environmental conditions. We first customized this model using estimates of demographic parameters...AuthorsBradley B. Shepard, Brian Sanborn, Linda Ulmer, Danny C.

- Commercial trapping of fishers (Martes pennanti) and American martens (M. americana) has been prohibited in California since the mid-1900's, yet concern continues to exist about the status of their populations. Recently developed methods for detecting the presence of forest carnivores have made it possible to estimate their distributions and, potentially, to index their populations. We summarize the characteristics and results of track-plate and line-triggered camera surveys that were condtucted in California to determine the presence of fishers or martens in areas scheduled for timber...AuthorsBill Zielinski, Richard L.
