Classification of wetlands on air/ground comparison transects in the prairie provinces : part I. waterfowl strata 30 to 33 - Saskatchewan part II. waterfowl strata 34 to 40 - southeastern Saskatchewan and Manitoba / J.B. Millar.
Material type: TextPublication details: 1982-1983.Description: 2 v. (various pagings) : ill. , maps ; 28 cmOnline resources: Abstract: The U.S. Fish and Wildlife Service has conducted annual aerial surveys of waterfowl breeding populations across large areas of Canada,including the three Prairie Provinces, each May since 1947. One component of this program has been the use of air/ ground comparison transects at selected sites across the prairies to provide a correction factor, through simultaneous bird counts by aerial and ground survey crews, for visibility biases in the more extensive aerial counts. Over the years some habitat data have been collected on individual wetlands on the air/ground transects. However, these efforts have been limited by the time constraints within which the survey crews must work and the fact that it is often difficult, particularly in high water years, to assess the full character of all wetlands in early May before new vegetation has developed. Current studies of breeding pair use and waterfowl recruitment on these transects require more detailed information than has hitherto been availItem type | Current library | Collection | Call number | Status | Notes | Date due | Barcode |
