Significant ecological features inventory of the Lesser Slave Lake integrated resource planning area /

Abstract

Centre for Resources Development at the University of Guelph during the 1970s. Eagles (1980, 1984) updated and further developed much of this work and documented various identification criteria. These criteria deal principally with the identification of areas that represent unique, unusual or remnant ecosystems, unique landforms, habitat for rare and endangered species, areas of unusually high biological diversity, areas that perform a vital ecological function and areas with significant scientific or educational potential. Studies by Eagles have formed the basis for criteria used in ESA and SEF studies in various jurisdictions in Alberta including the City of

Significance and disturbance study of Devonshire Beach-Lesser Slave Lake Provincial Park /

“…Lesser Slave Lake, located approximately 250 km north of Edmonton, is the second largest lake in Alberta, second only to the Lake Claire -Lake Athabasca complex that is located in the northeast corner of the Province (Bentz andSaxena 1993, Brandford andHanson 1990). The lake has a surface area of 1,150 sq km and maximum depths of 21 m (Bradley 1980).…”

“…Lesser Slave Lake is an extensive area that receives input from four major inlets: South Heart, Driftpile River, Swan River and Assineau River. The drainage basin is approximately 12,400 km 2 or 11 times greater than that of the lake (Mitchell andPrepas 1990, Saxena andBentz 1993). Adjacent areas undergoing resource exploitation by agriculture, oil and gas and forestry interests could potentially be impacting Lesser Slave Lake and subsequently, Devonshire Beach.…”
