Science in Support of Conservation
The Raincoast Education Society (RES) is actively involved in scientific research and monitoring in Clayoquot and Barkley Sound. Our work in this field may sometimes go ‘under the radar’, but it’s an important part of our mission. Our core staff includes several biologists who often work in collaboration with partners from other local, provincial, or national agencies and organizations. The RES enjoys the freedom of a broad mandate and the ability to focus on locally relevant issues that affect the communities we serve. From water sampling to shorebird tracking, every project the RES takes on seeks to collect data that can provide a solid, scientifically-based reference to inform local efforts to manage, enhance, protect and preserve the unique natural environment we live in and the species we share it with.
Pacific salmon have been relatively well studied due to their cultural, ecological and economical importance, but there are still many more questions than answers. One major gap is the lack of a clear understanding of what adult salmon eat – an important factor in at-sea survival! Seasonal, annual, and regional variations in salmon diet are likely extremely important factors affecting individual health and reproductive success.
While the decline of wild salmon stocks in BC is well recognized, the causes of these declines remain poorly understood. It’s likely that a combination of factors are responsible, and we want to learn more about what kinds of impacts variations and shifts in diet might be having on salmon.
Since 2019, The RES has been working in collaboration with the University of Victoria’s Fisheries Ecology and Marine conservation lab to collect diet samples from adult chinook and coho salmon in Barkley and Clayoquot Sound. While this program initially recruited participants fishing in the Salish Sea (eastern and southern Vancouver Island) and has expanded up the central coast and even to Haida Gwaii, the west coast of Vancouver Island has been very poorly sampled. The RES is working with local and visiting sport and commercial fishers to learn more about adult salmon diet by collecting the intact stomachs of landed fish. Anyone can participate! It’s super easy, lets you feel good about putting 100% of your fish to good use, and helps fill in some critical knowledge gaps that will help us learn more about how to protect the salmon in our communities.
The Tofino Mudflats Wildlife Management Area was established in 1997 in recognition of its importance as habitat for a wide variety of birdlife. Although the importance of the TMWMA as overwintering habitat for waterfowl is well recognized, survey efforts to date have been haphazard, inconsistent in methodology, and few and far between. Several local stakeholders which sit on the TMWMA Advisory Committee have raised concerns that recent development and changes in human use of the TMWMA and adjacent areas may be negatively affecting overwintering bird populations.
The RES is working in collaboration with The Nature Trust of BC to carry out a multi-year census of overwintering waterfowl in the Tofino Mudflats Wildlife Management Area. The goal of this project is to conduct a series of bimonthly on-the-water surveys during the winter (Nov-Apr) to determine the current abundance, diversity and distribution of overwintering waterfowl and other birds within the TMWMA and develop a baseline dataset with which to assess long-term trends. This project was begun in 2018 and will continue until at least 2020.
