Contains two layers: 1. Bull Trout Vulnerability Assessment: This analysis was generated to show the relative vulnerability of bull trout across the Columbia basin. Input variables include the prportion of valley bottom (e.g. floodplains), the average max summer temperature (July 15th to Sept 15th), and winter flood frequency (the frequency of high flow events exceeding the 95th percentile from December through March) for a given watershed. The estimates for temperature and flow were taken from the mouth of the watershed. This analysis includes historic and future (2040s scenario). Stream temperature and flow data are avaliable at rap.ntsg.umt.edu. See Wu H, Kimball JS, Elsner MM, Mantua N, Adler RF, Stanford...

Increased network capacity is a priority identified by the GNLCC and the RMPF Leadership Team to build on the organizational structure of LCC Partner Forums. Partner Forum organizations are intentionally inclusive collections of key decision-makers and stake-holders in the region who facilitate the flow of information and ideas, the delineation of shared priorities, and the advancement of projects leading to mutually beneficial outcomes. The ability of a Partner Forum to provide these services is directly related to the efficacy of its network. As the Partner Forum network improves, it successfully applies the outcomes of its work across the Rocky Mountain region and the greater GNLCC area.The importance of building...

Conclusions:The occurence of bull trout in mid-boreal stream is negatively related to two metrics of industrial activity: percent forest harvesting and road density. Bull trout abundance was positively related to elevation, and negatively related to stream width, slope, and levels of forest harvesting.Thresholds/Learnings:Timber harvest on up to 35% or more of individual subbasins is projected to result in the extripation of bull trout from up to 43% of stream reaches, especially those that support high densities of bull trout.

Abstract (from http://onlinelibrary.wiley.com/doi/10.1111/gcb.12850/abstract): Understanding how climatic variation influences ecological and evolutionary processes is crucial for informed conservation decision-making. Nevertheless, few studies have measured how climatic variation influences genetic diversity within populations or how genetic diversity is distributed across space relative to future climatic stress. Here, we tested whether patterns of genetic diversity (allelic richness) were related to climatic variation and habitat features in 130 bull trout ( Salvelinus confluentus) populations from 24 watersheds (i.e., ~4–7th order river subbasins) across the Columbia River Basin, USA. We then determined whether...

Bull trout (Salvelinus confluentus) status data created for the Western Division of the American Fisheries Society (WDAFS)
Native fish of the Columbia River Basin, and the ecosystems that support them, are an innate and critical part of Nez Perce culture. The persistence of these fisheries may be at risk due to climate change, especially in combination with other stressors (e.g., habitat fragmentation and disconnectivity). Assessing vulnerability of these fisheries to climate change, considering options for action, and taking action will require strategic collaboration and coordination with multiple partners. Here, we propose to start building those partnerships to address this landscape-level conservation concern.The overarching philosophy of Nez Perce fisheries management is to ensure that all species and populations of anadromous...

Parent Project: Range-Wide Climate Vulnerability Assessment for Threatened Bull Trout Publication Abstract: Forecasts of species distributions under future climates are inherently uncertain, but there have been few attempts to describe this uncertainty comprehensively in a probabilistic manner. We developed a Monte Carlo approach that accounts for uncertainty within generalized linear regression models (parameter uncertainty and residual error), uncertainty among competing models (model uncertainty), and uncertainty in future climate conditions (climate uncertainty) to produce site-specific frequency distributions of occurrence probabilities across a species’ range. We illustrated the method by forecasting suitable...

Salvelinus confluentus,
Bull Trout is the most cold-adapted fish in freshwaters of the Pacific Northwest. The species is listed as threatened under the U.S. Endangered Species Act, but climate warming may place the species at further risk. Climate warming may lead to warming of streams in summer and increasing probability of floods in winter, leading to widespread loss of habitat projected for Bull Trout. This project sought to further elaborate how these climate-related threats influence Bull Trout across five western states (OR, WA, ID, MT, NV). These states form the southern margin of the species’ range. We used predictions of temperatures in streams across approximately two-thirds of this extent to map coldwater streams or “patches”...

Abstract (from http://www.nrcresearchpress.com/doi/abs/10.1139/cjfas-2014-0098#.VN_BFGjF_gl): Linked atmospheric and wildfire changes will complicate future management of native coldwater fishes in fire-prone landscapes, and new approaches to management that incorporate uncertainty are needed to address this challenge. We used a Bayesian network (BN) approach to evaluate population vulnerability of bull trout ( Salvelinus confluentus) in the Wenatchee River basin, Washington, USA, under current and future climate and fire scenarios. The BN was based on modeled estimates of wildfire, water temperature, and physical habitat prior to, and following, simulated fires throughout the basin. We found that bull trout population...

The Geographic Information Retrieval and Analysis System (GIRAS) was developed in the mid 70s to put into digital form a number of data layers which were of interest to the USGS. One of these data layers was the Hydrologic Units. The map is based on the Hydrologic Unit Maps published by the U.S. Geological Survey Office of Water Data Coordination, together with the list descriptions and name of region, subregion, accounting units, and cataloging unit. The hydrologic units are encoded with an eight-digit number that indicates the hydrologic region (first two digits), hydrologic subregion second two digits), accounting unit (third two digits), and cataloging unit (fourth two digits). The data produced by GIRAS was...
This raster was created by merging the bull trout critical habitat lakes and streams from USFWS and bull trout streams from Streamnet. There are mostly the same but there are some differences. The raster was used in spatial operations where a raster version of bull trout distribution were required.
Winter flooding risk was measured by using the mean January - March temperature from PRISM 1980-2010 dataset. The future temperature was increased 3 degress C (based on Haak et al. 2010 methodology). Mean current and future temperatures were extracted for Bull trout analysis units. Temperatures below -1 degrees C were considered snow dominant, -1 to +1 degrees C were considered transient and greater than 1 degree were considered rain dominant.For winter flood risk:Stays Snow Dominant = Low RiskSnow Dominant to Transient = Moderate RiskSnow Dominant to Rain Dominant = High RiskStays Transient = Low RiskTransient - Rain Dominant = Moderate RiskStays Rain Dominant = Low Risk
This project will support the design and development of a large-scale aquatics monitoring program across 1.5 million acres of the Crown of the Continent, as part of a 10-year, landscape-level restoration project established and funded by the U.S. Forest Service in 2010. The Forest Service has directed each of ten Cooperative Forest Landscape Restoration Program projects to develop and implement a large-scale monitoring program to inventory current resource conditions and facilitate the short- and long-term evaluation of the effectiveness of restoration projects to inform future management strategies and actions: the work proposed here would address significant challenges associated with maintaining or improving...

Goal 3: Maintain hydrologic regimes,
Existing stream temperature data were compiled from numerous federal, state, tribal, and private sources to develop an integrated regional database. Spatial statistical models for river networks were applied to these data to develop an accurate model that predicts stream temperature for all fish-bearing streams in the US portion of the GNLCC. Differences between model outputs for historic and future climate scenarios were used to assess spatial variation in the vulnerability of sensitive fish species across the GNLCC.FY2011Objectives: Develop a regional stream temperature model that incorporates important climate drivers, wildfire/riparian conditions, and geomorphic factors; Use the model to understand and predict...

We propose a regional assessment of aquatic species vulnerabilities and responses to climate change as the basis for adaptive management for aquatic ecosystems in the Great Northern LCC, using the Transboundary Flathead Ecosystem as a case example. This region encompasses a complex mix of federal, state, tribal, and private lands in the US and federal, provincial and private lands in Canada. The complex suite of ownerships, international relations, and agency objectives establish their own set of challenges; however, all will experience a similar range of climatic (e.g., long-term drought and declining snow pack) and non-climatic (e.g., habitat fragmentation, shifting land- and water use patterns, and invasive species)...

These data identify (in general) the areas where proposed critical habitat for the bull trout (Salvelinus confluentus) occur.
The FSim burn probability was used to determine the burn probability of the bull trout range in the ecoregion. This layer was used to examine wildfire risk to areas within the bull trout range.
This dataset was created as a way to have standard fish distribution datasets across the various fish species for the study area. This was needed because the original source datasets for fish distributions came from several different sources and were at various scales and also overlapped. To fix the issues in the source datasets we walked the original data over to the NHD Plus hydrography. These data are provided by Bureau of Land Management (BLM) "as is" and may contain errors or omissions. The User assumes the entire risk associated with its use of these data and bears all responsibility in determining whether these data are fit for the User's intended use. The User is encouraged to carefully consider the content...
