Central Arctic waterfowl surveys, 1989-1991. 47 pp.
ABSTRACT
Cooperative
aerial surveys for Canada Geese (Branta canadensis hutchinsii),
White-fronted Geese (Anseralbifrons), and Tundra Swans (Cygnus
columbianus) were conducted by Ducks Unlimited Canada and the NWT
Department of Renewable Resources in the Kitikmeot Region, Northwest
Territories from 1989 through 1991.
Reconnaissance surveys were conducted in 1989 and 1990 to
determine the general locations of waterfowl concentrations, and as a
basis for comparison with past work.
Quantitative surveys were conducted by helicopter in 1990 and
1991 to determine waterfowl abundance.
The criterion of Alexander et al. (1 991), i.e., the presence of
1 % of the national population of a species, was used to assess whether
or not a new site should be recommended as a Key Migratory Bird
Terrestrial Habitat Site. Four
new areas are identified and recommended to the Canadian Wildlife
Service and the Nunavut Wildlife Management Advisory Board for this
designation: the western half of the Kent Peninsula; an area west of
Albert Edward Bay on Victoria Island; an area 60 km north of Coppermine;
and an area west of Cambridge Bay.
Two other areas were identified as warranting further
investigation, and two sites already classified as Key Migratory Bird
Terrestrial Habitat Sites were confirmed.
Populations of geese and swans have increased substantially since
the 1960s and 1970s in the Central Arctic. |
