Site details


Site description: St. Lawrence Lake is located approximately 15 km east of the town of Provost, in east-central Alberta. The lake is fairly alkaline and shallow, with no emergent vegetation. The lake fluctuates in size, being only half its normal size in the fall of 2000. The land around the land is mostly pastureland.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
Additional biodiversity: In the fall, St. Lawrence Lake supports from 10,000 to 30,000 white geese. Most of these birds are Snow Geese, but some are Ross Geese. The average number of 20,000 is a globally significant number. Ross Geese arrive earlier than the Snow Geese, which peak in early October, so these figures to not include peak Ross Goose numbers. About 2,000 to 4,000 Ross Geese are usually present in the spring and fall. Greater White-fronted Geese are also abundant between 5,000 and 10,000 are usually present. The higher number is about 1% of the North American population.
