Description

This monitoring plan was designed to address three objectives. First, to make a preliminary assessment of the status of all potential harlequin duck breeding streams in the bow Region of Kananaskis Country, and describe methods to continue this assessment with field work over a number of years. Second, to describe and assess the methods used to determine the population status of the ducks on the Elbow and Kananskis rivers; to assess the effectiveness of helicopter surveys used in central Alberta; and to recommend which methods to use to continue to estimate population size. Third, to describe and assess methods used to determine productivity of harlequin ducks on the Elbow and Kananskis rivers, and their validity for other streams.

Description

In 1996 harlequin ducks were added to the Yellow "A" list of endangered and threatened species in Alberta. Since 1995, research in Kananaskis Country has contributed significantly to an understanding of the habitat and conservation needs of harlequin ducks in the province. The objectives of the 2000 field season, the results of which are reported in this document, included investigating the abundance, population structure, survival rates, trends and productivity of harlequin ducks on the Elbow and Kananaskis rivers; continuing baseline work on the Sheep and Highwood rivers, and Cataract Creek; and to make recommendations regarding harlequin duck conservation.
