Conserving Birds and Critical Habitat in the Fraser River Estuary, an Important Bird and Biodiversity Area

In addition to being Canada’s largest salmon-producing river, the Fraser River Estuary supports over 1.7 million birds annually, making it the most productive bird habitat in Western Canada. The Estuary is also an internationally significant habitat – its continued health is an important contribution towards addressing the global biodiversity crisis.

To conserve global biodiversity, several leading international conservation organizations have been working to identify “Key Biodiversity Areas (KBAs)”. The Fraser River Estuary is among the first potential KBAs in Canada to be identified due to the large number and diversity of birds and other wildlife it supports. For example, the coastal habitats of the Estuary support over 1.4 million shorebirds such as Western Sandpipers; 240,000 waterfowl, such as Snow Geese; and approximately 4,000 raptors, such as Barn Owls.

The world’s population of Western Sandpipers is threatened by the proposed Roberts Bank Terminal 2 Project. You can help by writing to your federal elected officials.

The majority of the world’s Western Sandpipers depend biofilm found on the mudflats to fuel their migration.

Barn Owls thrive in the agricultural habitats around the Fraser River Estuary. Urban development, rodenticides, and vehicle collisions have all lead to the Barn Owl being listed as a Threatened species in BC.

Barn Swallows are small, acrobatic birds that catch insects in flight found on the Fraser River Estuary. Building nest platforms and insect-producing habitats helps to address the decline of these birds.

The use of Citizen Science apps such as eBird and iNaturalist have been critical in collecting large volumes of data for biodiversity and conservation research on the Fraser River Estuary.

How You Can Help

The birds of Fraser River Estuary need your help. The main threats to birds in the Estuary are habitat loss and climate change. Immediate action is needed from all levels of government to establish a conservation management plan for the Fraser River Estuary.

The Fraser Estuary Management Plan would need to address the specific issue of habitat loss due to increased shipping traffic and supporting infrastructure.

Community partners are seeking creative solutions to ensure agriculture continues to be practiced in a bird-friendly manner, building on the legacy of farmland stewardship practiced by the farmers of Delta. Strengthening existing beneficial practices while enhancing Indigenous-led conservation on the delta and advocating for ecosystem-based climate adaptation are just some examples of the work underway.

We need to restore the ecological function of the Estuary’s coastal wetlands – for birds and people.
