Climate shield cold-water refuge streams for preserving native trout

Documents and Media Posted on: March 18, 2015
Crowd-sourced biological datasets contributed by multiple agencies were coupled with high-resolution NorWeST stream temperature scenarios to delineate invasion resistant, climate refuge streams across >450,000 stream kilometers in the northwestern U.S. for two native trout species of concern — Bull Trout and Cutthroat Trout.Document Type: Briefing Papers

Climate shield cold-water refuge streams for native trout

Projects Posted on: March 18, 2015
The Climate Shield website hosts geospatial data and related information on specific locations of cold-water refuge streams for native cutthroat trout and bull trout across the American West. Forecasts about the locations of refugia could enable the protection of key watersheds, be used to rally support among multiple stakeholders, and provide a foundation for planning climate-smart conservation networks that improve the odds of preserving native trout populations through the 21st century.

The cold-water climate shield: Delineating refugia for preserving salmonid fishes through the 21st century

Publications Posted on: March 03, 2015
The distribution and future fate of ectothermic organisms in a warming world will be dictated by thermalscapes across landscapes. That is particularly true for stream fishes and cold-water species like trout, salmon, and char that are already constrained to high elevations and latitudes.

Documents and Media Posted on: January 23, 2015
Thermal regimes in rivers and streams are fundamental determinants of biological processes and are often monitored for regulatory compliance. Climate change and other factors associated with human development and land management pose significant threats to the thermal integrity of many streams and rivers.Document Type: Briefing Papers

Stream isotherm shifts from climate change

Documents and Media Posted on: January 23, 2015
Stream ecosystems are especially vulnerable to climate warming because most aquatic organisms are ectothermic and live in dendritic networks that are easily fragmented. Many bioclimatic models predict significant range contractions in stream biotas, but subsequent biological assessments have rarely been done to determine the accuracy of these predictions.Document Type: Briefing Papers

Spatial statistical modeling tools for streams

Documents and Media Posted on: January 23, 2015
Stream network structure, connectivity, and flow direction strongly affect spatial patterns in stream attributes. Most statistical analyses ignore network structure and may provide biased results for stream data. Key Findings:Document Type: Briefing Papers

Bull trout monitoring

Documents and Media Posted on: December 04, 2014
Bull trout (Salvelinus confluentus) are native to much of the Pacific Northwest, and although the species remains widely distributed, population declines prompted listing under the Endangered Species Act in 1999. As part of the recovery process, monitoring of bull trout populations for determination of status and trend is required.Document Type: Briefing Papers

Bull trout and climate change

Documents and Media Posted on: December 04, 2014
Like many fishes native to the Rocky Mountains and the Pacific Northwest, bull trout (Salvelinus confluentus) have declined in response to changes in flow regimes, habitat alteration, and invasion of non-native species. Climate change has only exacerbated these conditions and, as a result, the species is now distributed in highly fragmented populations throughout its range.Document Type: Briefing Papers
