Distribution and status of seven native salmonids in the interior Columbia River basin and portions of the Klamath River and Great basins

Publications Posted on: May 15, 2015
We summarized presence, absence, current status, and potential historical distribution of seven native salmonid taxa - bull trout Salvelinus confluentus, Yellowstone cutthroat trout Oncorhynchus clarki bouvieri, westslope cutthroat trout O. c. lewisi, redband trout and steelhead O. mykiss gairdneri, stream type (age-1 migrant) chinook salmon O. tshawytscha.

Climate change and Rocky Mountain native trout

Documents and Media Posted on: December 04, 2014
Like many fishes native to the Rocky Mountains and the Pacific Northwest, cutthroat trout (Oncorhynchus clarkii) and bull trout (Salvelinus confluentus) have declined, apparently in response to changes to flow regimes, habitat alteration, and the introduction of non-native species.Document Type: Briefing Papers

Role of climate and invasive species in structuring trout distributions in the interior Columbia River Basin, USA

Publications Posted on: August 31, 2011
Recent and projected climate warming trends have prompted interest in impacts on coldwater fishes. We examined the role of climate (temperature and flow regime) relative to geomorphology and land use in determining the observed distributions of three trout species in the interior Columbia River Basin, USA.

Anticipated climate warming effects on bull trout habitats and populations across the interior Columbia River basin

Publications Posted on: December 17, 2008
A warming climate could profoundly affect the distribution and abundance of many fishes. Bull trout Salvelinus confluentus may be especially vulnerable to climate change given that spawning and early rearing are constrained by cold water temperatures creating a patchwork of natal headwater habitats across river networks.

Coarse-scale restoration planning and design in Interior Columbia River Basin ecosystems: An example for restoring declining whitebark pine forests

Publications Posted on: September 04, 2007
During the last 2 years, many people from numerous government agencies and private institutions compiled a scientific assessment of the natural and human resources of the Interior Columbia River Basin (Jensen and Bourgeron 1993). This assessment is meant to guide the development of a coarse-scale Environmental Impact Statement for all 82 million hectares comprising the Interior Columbia River Basin (fig. 1).
