Loss of B.C. wetlands can amplify effects of extreme weather events

Wetlands in British Columbia are vital in protecting the environment from extreme weather events such as floods and droughts. However, climate change is putting them at risk due to unpredictable and volatile water cycles. Canada has lost up to 70% of its wetlands in developed areas, with the Lower Fraser Valley losing around 95%. Agriculture, urban expansion, and other land uses have stressed the remaining wetlands, resulting in habitat losses, drinking water losses, and lost recreation opportunities. Restorative efforts are underway, including removing parts of the Squamish Spit to reintroduce wetlands and landowners plugging drains to create marshes. Creating rain gardens in backyards and beavers building dams can also help restore wetlands.
