The Western Native Trout Initiative is all about getting projects done that will help improve the abundance of western native trout across a variety of landscapes. WNTI a collaborative effort of 12 western states including Alaska, the National Fish Habitat Action Plan, the U.S. Fish and Wildlife Service, Forest Service, Bureau of Land Management, and many tribal and public or private conservation-minded organizations (view partners). WNTI's goals and objectives include gathering project opportunities, funding, and partners together to make a measurable impact on native trout populations and habitats. WNTI projects are and will be funded by many different entities and partners.
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...

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...
