Resources available to conserve native trout are limited and must be targeted where conservation is most critical and likely to be successful. Using a grant from the GNLCC we collaborated with an Interagency Multi-State Yellowstone Cutthroat Trout (YCT) Conservation Work Group to prioritize conservation across the range of YCT. This prioritization will target national resources to critical conservation needs. We developed and applied a set of ecological and opportunity-based conservation criteria using the experience and knowledge of field managers. Ecological criteria were representation (genetic integrity and uniqueness), resilience (length or area of occupied habitat), and redundancy (number of populations or...

Despite extensive knowledge and data surrounding the status and threats to Yellowstone cutthroat trout there is currently no comprehensive framework for prioritizing conservation of populations and metapopulations (i.e., locations) and potential actions that could be taken in these locations to secure and expand populations, particularly in anticipation of climate change. Through our existing collaboration with state and federal management partners from Idaho, Wyoming, Utah, Nevada, and Montana, we propose to integrate existing information on Yellowstone cutthroat trout status and limiting factors in a spatially-explicit conservation priority framework adapted from a financial portfolio concept aimed at maximizing...

FY2011Thousands of data points have been collected by Oregon Department of Fish and Wildlife and Nevada Division of Wildlife from the 1950s to the present describing the distribution of declining native redband and endangered Lahontan cutthroat trout, and the invasive, nonnative brown and brook trout. USGS analyzed this data to understand the climate-related changes to species distributions and model extinction risk. The results, submittedfor publication, will be used by the State of Oregon as it drafts conservation plans for redband trout and by the Nevada Division of Environmental Protection in drafting water quality criteria to protect and monitor the states coldwater fisheries.

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. We review the state of knowledge on these important issues, focusing on Pacific trout in the genus Oncorhynchus. Although most research on salmonid fishes emphasizes Pacific salmon, we focus on Pacific trout because they share a common evolutionary history, and many taxa in western North America have not been formally described, particularly in the southern extent of their ranges....
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
