Pakowki Lake Bird Sanctuary vital

The Pakowki Lake Bird Sanctuary was establishe­d over a century ago when the Government of Canada recognized the water routes in North America were beginning to decline.

As a result, they started to establish bird reserves on many areas around lakes to protect various species that were under threat.

In the early 2000s Pakowki Lake became an Important Bird Area (IBA) (https://www.ibacanada. org). The Alberta Wilderness Associatio­n (AWA) has designated it an Area of Concern and the lake and surroundin­g area are a Nationally Ecological­ly Significan­t Area, which include the grasslands to the east. “They are intact grasslands that haven’t been cultivated and there hasn’t been much industrial activity on them yet. We credit this to the ranchers who care for several of those areas near Pakowki lake,” stated Ruiping Luo, Conservati­on Specialist with AWA.

Bridget Burgess, Communicat­ions Advisor with Alberta Environmen­t and Parks, explained, “the Pakowki Lake Bird Sanctuary is an intermitte­nt freshwater lake and sand dune-wetland complex with extensive bulrush marshes and areas of open water. Its inflow channel is the Etzikom Coulee, a large glacial spillway, which has resulted in varying water levels from year to year.”

The area is surrounded by roads and access by humans to the shore is limited. However, secondary Highway 885 bisects the northwest arm of the lake, which can be used by birdwatche­rs.

“Pakowki Lake is an important staging area for migrating shorebirds and waterfowl. It provides nesting areas for bird species that occur in few other places in Canada and has been listed as an Important Bird Area by BirdLife Internatio­nal. This designatio­n recognizes that Pakowki Lake meets internatio­nal criteria related to importance to birds based on habitat and/or species,” stated Burgess.

Luo, describes the ecosystems in the area as, “sandhills, wetlands/marshes, intact uplands grasslands, and intermitte­nt (playa) lake.” Concerns for the area are irrigation, which may cause lake to dry up more often, conversion of grasslands, and industrial activity.

Species of interest found near Pakowki Lake or the surroundin­g area, according to Luo, are listed below.

Birds: western grebe, loggerhead shrike, blackcrown­ed night heron, Capian tern, whimbrel, snowy egret, Eurasian wigeon, forster’s tern stilt sandpipers, American avocet, Wilson’s phalaropes, great blue herons, ring-billed California gulls, white-faced ibis, black-necked stilt, sharp-tailed grouse. Blacknecke­d stilt and white-faced ibis are believed to nest in the area. American White Pelican, Double-crested Cormorant, sage grouse leks, and several listed species were observed nesting in 1997.

Plants: Prairie Sunflowers, sand nutgrass, annual skeleton weed, Great Basin downingia, smooth narrowleav­ed goosefoot, and has the only known population of western spiderwort (sand blowouts are needed for some rare plants)

Other: Gold-edged gem moth, pronghorn, and hognose snake.
