2010 Pond Numbers

Prairie Canada Pond Numbers

Prairie Canada Pond Numbers

Conditions across the Canadian prairies were similar to 2009. Portions of southern Alberta, Saskatchewan and Manitoba improved but a large area along the Alberta and Saskatchewan border remained dry, and moisture levels in portions of Manitoba declined from last year. The 2010 estimate of ponds in Prairie Canada was 3.7 ± 0.2 million. This was similar to last year's estimate (3.6 ± 0.1 million) and was similar to the 1955-2009 average (3.4 ± 0.03 million). Residual water remains in the Parklands and these were classified as fair to good. Most of the Prairie-Parkland region of Canada received abundant to historically high levels of precipitation during and after the survey which, while possibly flooding some nests, will produce excellent brood-rearing habitat for successful nesters and lessen the summer drawdown, leading to beneficial wetland conditions next spring.

North Central U.S. Pond Numbers

North Central U.S. Pond Numbers

Wetland numbers and conditions remained fair to good in the eastern U.S. prairies, but habitat conditions declined through the western Dakotas and Montana. The 2010 pond estimate for the north-central U.S. of 2.9 ± 0.1 million, which was similar to last year's (2.9 ± 0.1 million) and 87% above the long-term average (1.6 ± 0.02 million). Fall and winter precipitation in the eastern Dakotas generally improved good habitat conditions already present. However, wetlands in the western Dakotas and Montana were not recharged, resulting in a deterioration of conditions from 2009, at the time the survey was conducted.

Habitat conditions during the 2010 Waterfowl Breeding Population and Habitat Survey were characterized by average to below-average moisture and a mild winter and early spring across the entire traditional (including the northern locations) and eastern survey areas. The total pond estimate (Prairie Canada and U.S. combined) was 6.7 ± 0.2 million. This was similar to the 2009 estimate and 34% above the long-term average of 5.0 ± 0.03 million ponds.
