Nature and Culture
The Pitt-Addington Marsh WMA supports over 200 bird and 29 mammal species.
The area provides important wintering, migration and breeding habitat
for waterfowl, shorebirds, raptors, passerine and upland species. Of particular
note is the presence of Greater Sandhill Cranes feeding and nesting in
and adjacent to the WMA; it is one of only two nesting sites in the Lower
Fraser Valley. Other bird species include Canada Goose, Mallard, American
Wigeon, Teal, Pintail and Wood Ducks. Raptors, most common during the
winter months, include Northern Harrier, Sharp-shinned Hawk, Red-tailed
Hawk, Bald Eagle, Kestrel, Turkey Vulture and Osprey. Black Bear, Mule
Deer and Coyote are seen regularly, and Cougar have been reported on occasion.
Rare elements identified in the WMA include Pointed Broom Sedge, Two-edged
Water-starwort and Sessile-leaved Sandbar Willow.
Physiography, Climate and Vegetation
This WMA is generally a flat, alluvial floodplain made up of dyked and
undyked areas. Pitt Lake is the largest tidal freshwater lake in the world.
There is a rare reverse delta at the mouth of the Pitt River, a result
of deposition which occurs when rapidly flooding tides dam and reverse
the main Fraser River outflow back up into Pitt Lake. The WMA also contains
Pitt Polder Ecological Reserve, an area of sedge bog and two forested
granitic outcrops rising 114 metres above the floodplain.
Compatible Resource and Recreation Uses
Parts of the WMA accommodate wildlife viewing and limited seasonal hunting.
