Book excerpt: Exerpt From Abstract: "The distribution and abundance of westslope trout (Salmo clarki lewisi) has drastically declined over its historic range in the last 100 years. Although previous studies in Montana have identified strongholds, the status of westslope cutthroat statewide continued to be an uncertainty. The purpose of this report was to quantitatively determine the present and historic range as well as identify strongholds of genetically pure westlopw cutthroat in Montana... Statewide, 259 lakes contain or are believed to contain westslope cutthroat populations. Six percent are known to contain genetically pure populations. Fifteen of the 16 pure populations are found within Glacier National Park; the other population is located on the Flathead Indian Reservation. Only 4 lakes or reservoirs east of the continental divide were found to contain westslope populations."

This book was released on 2010 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reported decline of native bull trout Salvelinus confluentus and westslope cutthroat trout Oncorhynchus clarkii lewisi populations west of the Continental Divide in Glacier National Park (GNP) prompted research to identify critical habitats and investigate factors influencing their distribution and relative abundance. I evaluated the association of six abiotic factors (stream width, elevation, gradient, large woody debris density, pool density, mean August stream temperature) and a biotic factor (the presence of nonnative lake trout, Salvelinus namaycush) with the occurrence and density of bull trout and westslope cutthroat trout in 79 stream reaches in five sub-drainages of the North Fork Flathead River in GNP. Logistic and linear regression models were used to quantify the influence of these independent variables on species occurrence (presence/absence) and density (age-1 or older fish/100m2), and an information theoretic approach (AICc) was used to determine the most plausible combinations of variables in each case. The occurrence of westslope cutthroat trout was negatively associated with the presence of lake trout and positively associated with large woody debris and water temperature. Westslope cutthroat were detected throughout a wide range of water temperatures (8.5-16oC), stream sizes and elevations, but were most abundant in small, complex streams that were not connected to lakes supporting lake trout. Bull trout occurrence was positively related to stream width and negatively related to channel gradient and water temperature. Bull trout were most abundant in narrow (

This book was released on 2015 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although many Westslope Cutthroat Trout Oncorhynchus clarki lewisi populations in Idaho are robust and stable, others are depressed. In some systems, such as the South Fork Clearwater River (SFCR) system, environmental conditions (e.g., summer temperatures) are hypothesized to limit populations of Westslope Cutthroat Trout. Radiotelemetry and snorkeling methods were used to describe movement, distribution, and habitat use of Westslope Cutthroat Trout in the SFCR in 2013 and 2014. Sixty-six tags were implanted into fish (155–405 mm). Sedentary and mobile summer movement patterns of Westslope Cutthroat Trout were observed. Sixty-two sites were snorkeled along the mainstem SFCR from 5–14 August 2014 to better describe the distribution of Westslope Cutthroat Trout. Twenty-three Westslope Cutthroat Trout were observed in 12 sites and at low density (mean ± SD; 0.0003 ± 0.0008 fish/m2 ). Results indicate that summer temperature was the primary factor limiting the distribution of Westslope Cutthroat Trout in the system.
