"In 1987, the Canadian Wildlife Service (CWS) and the Long Point Bird Observatory (LPBO) initiated a project to expand the Ontario Lakes Loon Survey (OLLS) in an effort to determine the relationship between the reproductive success of Common Loons and lake chemistry across a large area of eastern, central and northern Ontario. Since the project examines long-term reproductive success of loons in Ontario, it could form an integral part of the biological monitoring programme being developed by the Canadian Wildlife Service for eastern Canada. Administered by the LPBO, the OLLS consists of a series of surveys conducted by CWS staff and a network of volunteers. In this paper, we review some of the major results from surveys done in 1987 and 1988, discuss the value of the OLLS as a tool for monitoring loon production in relation to acid rain in Ontario, and identify areas which must be improved prior to incorporation into the overall CWS Biomonitoring program"--Abstract, p. vi.
