Freshwater Habitat Requirements of Anadromous Cutthroat Trout and Implications for Forestry Impacts Rosenfeld, Jordan

Abstract: This report evaluates the freshwater habitat requirements of juvenile anadromous cutthroat trout based on independent field research and published studies, and evalutes the effectiveness of the B.C. Forest Practices Code riparian regulations in protecting sea-run cutthroat trout habitat. Until the early part of the 1990s, most streams in coastal British Columbia were clearcut to the streambank, resulting in the cessation of inputs of Large Woody Debris (LWD) from riparian zones. LWD from riparian (streamside) trees falling into the stream channel is the major pool-forming mechanism in small and medium-sized coastal streams, where pools and the complex structure associated with LWD provide critical habitat for juvenile salmonids. Channel structure and juvenile rearing capacity in many south coastal streams impacted by logging will continue to declien in the foreseeable future (over the next 50-100 years) until riparian forest matures sufficiently for larger trees to begin dying and entering the stream channel in significant numbers.
