Effects of habitat complexity loss on eastern slope Rocky Mountain Brook Trout populations
Western U.S. rivers are currently influenced by legacy effects of reduced large wood (LW) loading and retention that has led to reduced in-stream habitat complexity. Historical land use practices such as tie-driving, snag removal, and beaver trapping have all contributed to declines in either input or retention of LW in mountain streams. Effects from these practices have persisted over a century after the activities ceased; suggesting streams have entered an alternative stable state. The alternative state is characterized by loss of multi-thread stream reaches, reduced sediment and nutrient ...
