Conservation of native Pacific trout diversity in Western North America

Publications Posted on: June 29, 2016
Pacific trout Oncorhynchus spp. in western North America are strongly valued in ecological, socioeconomic, and cultural views, and have been the subject of substantial research and conservation efforts. Despite this, the understanding of their evolutionary histories, overall diversity, and challenges to their conservation is incomplete.

The range-wide bull trout eDNA project

Projects Posted on: February 04, 2016
The bull trout has a historical range that encompasses many waters across the Northwest. Though once abundant, bull trout have declined in many locations and is now federally listed and protected under the Endangered Species Act. Rocky Mountain Research Station scientists initiated the range-wide bull trout eDNA project in partnership with biologists from more than 20 organizations to create sound and precise information about the distribution of bull trout in thousands of streams across their range.

A mathematical model of salmonid spawning habitat

Publications Posted on: May 14, 2015
A simulation model [Salmonid Spawning Analysis Model (SSAM)I was developed as a management tool to evaluate the relative impacts of stream sediment load and water temperature on salmonid egg survival. The model is for estimating acceptable sediment loads to spawning habitat that may result from upland development, such as logging and agriculture.

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.

Climate change impact on salmonid spawning in low-gradient streams in central Idaho, USA

Publications Posted on: December 28, 2011
Climate change is often predicted to cause a significant perturbation to watershed hydrology. It has been generally associated with negative impacts on natural systems, especially in conjunction with conservation and protection of sensitive ecosystems.
