Nature and Culture
habitat for many bird species, Boundary Bay is also a vital link
in the Pacific Flyway, supporting over 1.5 million birds from three continents
and 20 countries. The Boundary Bay, Sturgeon Bank and South Arm
Marshes Wildlife Management Areas have been designated as Western Hemisphere
Shorebird Reserve Network sites. As part of the larger Fraser estuary,
it supports the largest wintering shorebird and waterfowl populations
in Canada. The area also provides habitat for significant numbers
of raptors and marine mammals. Common species in the WMA include Mallard,
American Wigeon, Brant, Great Blue Heron, Black-bellied Plover, Dunlin,
Western Sandpiper, Mew Gull, Rough-legged Hawk, Red-tailed Hawk, Northern
Harrier, Peregrine Falcon and Bald Eagle. The last Canadian nesting population
of Barn Owl is concentrated in the Fraser delta, and forages in
the Boundary Bay area. The bay supports nearly two-thirds of the Fraser
Harbour Seal population, attracts Grey and Killer Whales, and provides
nursery and feeding areas for salmonids. The eelgrass beds are important
spawning sites for Pacific Herring.
Physiography, Climate and Vegetation:
The WMA is made up of intertidal salt marshes, mudflats, and open water
marine habitats. The salt marsh habitats support Sarcocorina pacifica
(Sea Asparagus) communities, as well as various grasses. The low intertidal
zones support extensive eelgrass beds.
Compatible Resource and Recreation Uses:
Parts of the WMA accommodate wildlife viewing and limited seasonal hunting.
