Current Research

I have over 25 years experience working with fisheries resources in the Rocky Mountain Region to provide technical and logistical support to the team of research scientists in Boise, Idaho. I have taken a career path that has led from instream flow and stream salmonid population dynamics in the waters of Wyoming and Colorado, to radio telemetry of endangered fishes in the canyons of the Green River in Utah, to describing species assemblage and distribution of fishes in Montana prairie streams. In my present position as a fisheries biologist at the Rocky Mountain Research Station I am involved with research projects on the life history, movements, spawning site selection, and habitat utilization by fluvial Bull trout and the spatial and temporal distribution of spawning Chinook salmon.

I recently completed the compilation and analysis of fifteen years of redd surveys and writing a manuscript detailing the fine-scale attributes of Fluvial Bull Trout redds in a headwater tributary for submission to a peer-reviewed fishery journal.

Research Interests

I conduct research in remote backcountry forest locations to gather information utilizing radio telemetry that includes the movement, homing, and habitat use of adult fluvial Bull trout (Salvelinus confluentus); the timing and extent of dispersal by juvenile bull trout; the spatial and temporal distribution of wild Chinook salmon (Oncorhynchus tshawytscha) in wilderness watersheds.

Why This Research is Important

I believe the recognition of the timing and extent of adult movements, the dispersal of juveniles, will help develop an understanding of local fish populations, the various habitats used at different life stages thus enabling fishery managers in identifying population bottlenecks, use of critical habitats, passage requirements, and fidelity to natal spawning grounds and aid the Forest Service in the implementation of conservation plans.
