Redd Counting for Bull Trout | The Nation-Wide Fisheries Program
The Davis River, located in the remote wilderness of Northern British Columbia, is home to one of the longest running data sets in the region. For the past 20 years, Chu Cho Environmental has been conducting annual redd counts in the river's index sections to monitor the population of Bull Trout, a species that is particularly sensitive to changes in water temperature. The health of this species serves as a barometer of the health of the entire ecosystem.
The Chu Cho Environmental team, led by Fisheries Biologist Bryce O'Connor, travels to the river's remote location via helicopter to conduct the survey, which requires meticulous searching of the stream's substrate. With each redd, the team coordinates and calibrates with each other to reduce observer variability as much as possible, prioritizing experienced observers in the more difficult sections.
This monitoring program provides essential data to inform regional conservation initiatives, helping to mitigate development impacts and preserve critical habitats for the long term. By ensuring the health of Bull Trout populations and their habitats, Chu Cho Environmental is not only safeguarding these species but also positively impacting the co-occurring species and downstream ecosystem.
Working on this project is a privilege and source of pride for Chu Cho Environmental, as it provides not only an enjoyable experience for the team but also a way to contribute to the well-being of the region. The monitoring program, conducted every year, ensures that the population is kept under close watch, allowing for rapid response and effective management of potential threats. By preserving these headwater areas, Chu Cho Environmental is helping to maintain a healthy ecosystem that benefits the entire Williston Reservoir watershed in Tsay Keh Dene territory.
