WATERFOWL BREEDING GROUND SURVEY OF REDVERS AREA, 
SASKATCHEWAN, 1952-1955 
Jerome H. Stoudt and Bruce A. Yeager 
Introduction 
The Redvers Study Area was established in 1952 in the aspen-parklands 
habitat type of southwestern Saskatchewan in order to study waterfowl population 
dynamics, habitat preference and the effects of water, climate and predators upon 
the production and survival of young. The population data obtained was also to be 
used as a standard with which to determine percentages of breeding pairs and 
breods which were missed by aerial crews in this habitat type. Following is a 
brief summary of findings during the three-year period from 1952-1955. 
Weather and Water Conditions 
From the graph which appears below can be noted that water levels on 
May 1, 1955 were 33 inches higher than on May 1, 1954 and that 1955 water levels 
never did recede as far as the maximum levels reached during 1952-1954.
