Mountain streams provide important habitats for many species, but their faunas are especially vulnerable to climate change because of ectothermic physiologies and movements that are constrained to linear networks that are easily fragmented. Effectively conserving biodiversity in these systems requires accurate downscaling of climatic trends to local habitat conditions, but downscaling is difficult in complex terrains given diverse microclimates and mediation of stream heat budgets by local conditions. We compiled a stream temperature database (n = 780) for a 2500-km river network in central Idaho to assess possible trends in summer temperatures and thermal habitat for two native salmonid species from 1993 to 2006....

For the past six years, the Bureau of Reclamation (BOR) has funded the USGS to study fish responses to restoration efforts and to construct a model relating stream habitat with fish population dynamics in the Methow River Basin, a tributary of the Columbia River. In the proposed study, we will use fish growth, distribution and movement (USGS data), foodweb data (Idaho State University), river flow (BOR data that we will expand) and water temperature data (from numerous agencies) to develop spatially-explicit bioenergetics models to assess effects of climate change on the viability of resident salmonid populations based on models being developed by USGS. The bioenergetics models will integrate such things as climate-change...

Abstract 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. The extreme climates in those environments also preclude invasions by most non-native species, so identifying especially cold habitats capable of absorbing future climate change while still supporting native populations would highlight important refugia. By coupling crowd-sourced biological datasets with high-resolution stream temperature scenarios, we delineate network refugia across >250 000 stream km in the Northern...

Bull trout (Salvelinus confluentus), listed as threatened under the Endangered Species Act, are among the more thermally sensitive of coldwater species in North America. The Boise River upstream of Arrowrock Dam in southwestern Idaho (including Arrowrock Reservoir) provides habitat for one of the southernmost populations of bull trout. The presence of the species in Arrowrock Reservoir poses implications for dam and reservoir operations. From 2011 to 2014, the Bureau of Reclamation and the U.S. Geological Survey collected fish telemetry data to improve understanding of bull trout distribution and movement in Arrowrock Reservoir and in the upper Boise River tributaries. The U.S. Geological Survey compiled the telemetry...
In May 2014, the GNLCC Steering Committee approved two pilot projects explore approaches to landscape-scale coordination to enhance science-based management across the GNLCC. The two ‘Shared Landscape Outcomes’ pilots were designed to assess and focus on specific pairs of a GNLCC Goal and a priority landscape stressor (as defined in the Strategic Conservation Framework) and focus the approach at the entire GNLCC scale. The two pilot projects focused on (1) the Connectivity goal and Land Use Change stressor (described here) and (2) the Aquatic Integrity goal and Invasives stressor and (see: https://www.fws.gov/science/catalog )Connectivity Pilot:Wildlife species are becoming increasingly isolated in patches of habitat,...

This GIS dataset is the primary data product produced for the NW Climate Science Center-funded project, "Rangewide climate vulnerability assessment for threatened Bull Trout" (FRESC Study ID 851). We used predictions of temperatures in streams across approximately two-thirds of the species' range in the U.S. to map coldwater streams or “patches” suitable for spawning and early rearing of Bull Trout. Each patch consists of streams with contiguous reaches of cold water. Patches were delineated using medium resolution National Hydrography Dataset streams containing modeled temperatures available at 1 km intervals, as provided by the NorWeST project (http://www.fs.fed.us/rm/boise/AWAE/projects/NorWeST.html).Once the...

Baseline fish health information on pallid sturgeon and bull trout or appropriate surrogate species (shovelnose sturgeon, cutthroat trout, mountain whitefish) in critical habitats with elevated risks of oil spills. Shovelnose sturgeon (Scaphirhynchus platorynchus) were collected in three locations near the confluence of the Missouri and Yellowstone Rivers and cutthroat trout (Oncorhynchus clarki lewisi) and mountain whitefish (Prosopium williamsoni) were collected from critical bull trout habitat along the Middle Fork of the Flathead River. Fish health metrics evaluated included gene expression/enzyme induction in various tissues, differential changes in white blood cells, polycyclic aromatic hydrocarbon bile metabolites,...
The Cascadia Partner Forum will complete conservation design for four Great Northern Landscape Conservation Cooperative conservation targets with significance to the transboundary Cascadia landscape to inform sound, data-driven management planning and action. This project aims to complete conservation design at the Cascadia-wide scale for grizzly bear, salmon, aquatic, and terrestrial connectivity to contribute to the Great Northern LCC Science Plan, while providing input and integration to the coarser-scale GNLCC-wide Science Plans established objectives, threats, metrics, and conservation actions for each target. Additionally, the Forum will conduct analyses on a common Great Northern LCC landscape stressor roads...

Field estimates of the abundance of two trout species (bull trout and westslope cutthroat trout) in Montana and rainbow trout in Washington and British Columbia were collected in concert with environmental DNA samples (eDNA) to evaluate if eDNA copy numbers correlated with abundance of trout. In addition, stream habitat data including channel units (pools, riffles), substrate, large woody debris, among others, were collected at sites.
The dataset includes measurements of stream habitat, fish abundance of westslope cutthroat trout and bull trout, and species-specific measures of environmental DNA (eDNA) from within the water. The data covers multiple streams in western Montana.
The number of fish barriers within the analysis unit was analyzed for the bull trout range within the ecoregion.
These data identify (in general) the areas where final critical habitat for the bull trout (Salvelinus confluentus) occur.
Using temperature range derived in earlier datasets for the range of bull trout in the ecoregion, the following assumptions are made of a future climate scenario.Suitable is Marginal is current Mean July Air Temp + 1 Standard Deviation - Max July Air Temp (32.4 - 33.9*C)Unsuitable is > current Max July Air Temp (> 33.9*C)Results are rolled up to an analysis unit.
303(d) listed waterways was downloaded from the EPA website. Areas listed as 303(d) were extracted and compared to the overall amount of non 303(d) waterways to establish a percentage of waterways that were 303(d).
Streams are classified as perennial (flowing uninterrupted, year-round) or intermittent (flowing part of the year) or ephemeral (flowing only during rainfall events). The classifications of “streamflow permanence” were primarily established in the middle 20th century and are often outdated and inaccurate today if they were not adjusted for changes in land use, wildfires, or climate.Understanding where streams are perennial is important for a variety of reasons. For example, perennial streams receive special regulatory protections under a variety of statutes, and provide important habitat for fish, wildlife, and other species. To predict the likelihood that streams are perennial, we compiled nearly 25,000 observations...
