Distribution, Status, and Land Use Characteristics of Subwatersheds within the Native Range of Brook Trout in the Eastern United States
We examined and summarized existing knowledge regarding the distribution and status of self- sustaining populations of brook trout Salvelinus fontinalis at the subwatershed scale cross their native range in the eastern USA. This region represents approximately 25% of the species’ entire native range and 70% of the U.S. portion of the native range. This assessment resulted in an updated and detailed range map of historical and current brook trout distribution in the study area.
Assessment and predictive model for brook trout (Salvelinus fontinalis) population status in the eastern United States
Over the last 200 years, brook trout (Salvelinus fontinalis) have been subjected to numerous anthropogenic physical, chemical, and biological perturbations that threaten the long term viability of brook trout throughout their historic native range. The historic and current decline in brook trout populations and the threat of further habitat degradation have led to a desire to develop a large scale conservation strategy to protect and rehabilitate brook trout populations and habitat. Understanding both the current distribution of brook trout and the relationships between the brook trout population status and perturbations is essential to developing meaningful conservation strategies and tactics.
