Conclusions: In fragmented watersheds, macrohabitat attributes measured at the patch scale were far more effective in predicting trout translocation success than measurements taken at the landscape scale Thresholds/Learnings: As a course filter indicator of cutthroat trout translocation success, the study found that translocations have a greater than 50% chance of fruitful establishment in watersheds >14.7km2 in area. Synopsis: This study aimed to identify stream-scale and basin-scale macrohabitat attributes limiting successful translocation and persistence of native cutthroat trout populations in fragmented landscapes along the Rio Grande. The study developed models of habitat attributes measured at two scales...

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...

Accurate assessment of species identity is fundamental for conservation biology. Using molecular markers from the mitochondrial and nuclear genomes, we discovered that many putatively native populations of greenback cutthroat trout (Oncorhynchus clarkii stomias) comprised another subspecies of cutthroat trout, Colorado River cutthroat trout (Oncorhynchus clarkii pleuriticus). The error can be explained by the introduction of Colorado River cutthroat trout throughout the native range of greenback cutthroat trout in the late 19th and early 20th centuries by fish stocking activities. Our results suggest greenback cutthroat trout within its native range is at a higher risk of extinction than ever before despite conservation...

Field surveys were conducted during 1997 and 1998 documenting the distribution and abundance of Colorado River cutthroat trout (Oncorhynchus clarki pleuriticus) in Escalante River tributaries. This documented occurrence of native trout in the Escalante River drainage of southern Utah represents an expansion of the known historic range of this subspecies as reported before the 1990s. We found 5 populations of native trout ranging in biomass from 3.0 to 104.2 kg ha-1 and occupying 13.2 km of stream of 130 km of estimated historic habitat. Current distribution and abundance of Colorado River cutthroat trout were compared to early introductions of nonnative trout stocked for sport fishing purposes. Native cutthroat...

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...

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...

Cutthroat trout (CT; Oncorhynchus clarki ssp.) are extremely imperiled owing to a variety of stressors. Changing climate is adding to these stressors that have already relegated CT in the Southern Rocky Mountains to less than 35% of their native habitat. The Rio Grande CT (O. c. virginalis) occupies 12% of its native range and is currently under review for ESA listing as federally threatened. Changing thermal regimes, hydroclimate, and disturbance regimes will continue to alter the remaining habitat of Rio Grande CT. An understanding the status and trends of Rio Grande CT thermal habitats and the vulnerability of these habitats to climate driven changes in temperature and stochastic disturbance regimes would enable...

The Colorado River Cutthroat Trout (CRCT) conservation team identified a need to further develop a long-term approach to updating and maintaining the CRCT GIS-based database that was created using the Inland Cutthroat Trout Protocol (ICP). The maintenance and upkeep of the database is critical to the annual and 5-year CRCT status reviews and prioritization of conservation actions. With concurrence from the Desert Fish Habitat Partnership, Western Native Trout Initiative (WNTI) used $18,000 in funds in the AFWA sub-grant to help fund the development of a web-based application for viewing and editing the data for CRCT as well as other cutthroat species (Greenback cutthroat trout and Rio Grande cutthroat trout)....
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...
Conclusions: At small spatial scales, where extirpation risks are high, landscape fragmentation will likely have long-term negative consequences on the genetic variation of individual assemblages of coastal cutthroat trout. Thresholds/Learnings: Synopsis: This study aimed to determine if coastal cutthroat trout were genetically structured within streams and to assess the effects of habitat fragmentation on coastal cutthroat trout genetic variation. Habitat fragmented by roads and other human disturbances acted as dispersal barriers, which strongly influenced coastal cutthroat trout genetic structure, diversity, and differentiation. At range-wide spatial scales, fragmentation potentially contributes to coastal cutthroat...

Like many other species, cutthroat trout (Oncorhynchus clarki) have declined substantially relative to historic conditions, and many existing populations are isolated. To inform conservation and restoration efforts for stream-resident cutthroat trout, I built a stage-structured stochastic simulation model to explore the dynamics of populations in isolation or connected by immigration. Relatively small increases in carrying capacity substantially reduced extinction risk in small, isolated populations. In the sensitivity matrix, the two most important elements affecting population growth rate were the survival of subadults that became reproductively mature the next year and the survival of young-of-the-year fish....

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...

The Colorado River Cutthroat Trout (CRCT) conservation team identified a need to further develop a long-term approach to updating and maintaining the CRCT GIS-based database that was created using the Inland Cutthroat Trout Protocol (ICP). The University of Wyoming Geographic Information Science Center was contracted to develop a multi-state, web-based database and a web-based application for viewing and editing the data to aid in conservation activities. Previously, Colorado, Utah and Wyoming all used separate, desktop databases that could not be shared with partnering agencies nor updated for all users simultaneously. The database and application is for CRCT as well as other cutthroat species (Greenback cutthroat...
