Breeding waterfowl use of restored wetlands in the Cariboo region of British Columbia
This study investigated effects of wetland size and emergent vegetation cover on breeding waterfowl and young at 12 restored wetlands in the Cariboo region of British Columbia. Repeated ground surveys were conducted throughout summer 2019 to determine total abundance, density and species richness of waterfowl. Surveyed wetlands varied in size and emergent cover. Large (16-19 ha) wetlands had greater breeding total abundance and lower breeding and brood densities than smaller wetlands. Total abundance of breeding waterfowl and young were highest when wetlands had less than 60% emergent cover. Previous studies suggest that high densities of waterfowl decrease young survival. Restorations created to benefit several species of breeding waterfowl may want to restore wetlands that are large (>16 ha) and have less than 30% emergent vegetation cover. These wetlands had higher total abundances and lower densities than other categories studied, however, certain species may depend on smaller wetlands which should be researched further., Cariboo region, wetland restoration, breeding waterfowl, emergent vegetation
Eco-cultural restoration of wetlands at Tl’chés (Chatham Islands), British Columbia, Canada
My research project examined the restoration possibilities for two culturally important wetland ecosystems at Tl’chés (Chatham Islands, British Columbia, Canada). The first wetland is a sacred bathing pool and holds cultural significance, the second is a remnant silverweed and springbank clover (Potentilla anserine ssp. pacifica and Trifollium wormskjoldii) root garden. These wetlands are necessary ecosystems for the wildlife on Tl’chés as wetlands are rare, but also an integral part of Songhees’ cultural practices. My work was done at the invitation from elder Súlhlima (Joan Morris) who was one of the last resident of the islands and retains hereditary rights there, and Songhees Chief Ron Sam and band council. The goal of my project was to develop a restoration plan to restore the wetlands to pre-abandonment conditions, so cultural practices can continue, and to benefit the islands native plant and animal species. The project highlights the value of combining traditional ecological knowledge (TEK) and traditional resource and environmental management (TREM) practices with ecological restoration., Eco-cultural restoration, wetland ecosystems, traditional ecological knowledge (TEK), traditional resource and environmental management (TREM), estuarine root gardens, Songhees First Nation
