Despite drier conditions this spring compared to last year, overall duck numbers edged up slightly compared to last year in the U.S. Fish and Wildlife Service’s 2015 Trends in Duck Breeding Populations, which was released today.
According to a press release from Ducks Unlimited, total populations were estimated at 49.5 million breeding ducks in the survey area, which is 51 percent above the 1955-2014 long-term average and the highest count on record.
Last year's estimate was 49.2 million birds, the release states.
“We are fortunate to see continued high overall duck populations in North America’s breeding areas this year,” DU CEO Dale Hall said in the release. “Though conditions were dry in some important habitats, we had large numbers of birds returning this spring and good conditions in the boreal forest and other areas of Canada. It looks like some typical prairie nesters skipped over the U.S. prairies and took advantage of good conditions farther north. This is an important reminder about the critical need for maintaining abundant and high-quality habitat across the continent.
“The boreal forest, especially, can provide important habitat when the prairies are dry. But the boreal is under increasing threats from resource extraction.”
The main determining factor for duck breeding success is wetland and upland habitat conditions in the key breeding landscapes of the prairies and the boreal forest. Conditions observed across the U.S. and Canadian survey areas during the 2015 breeding population survey were drier than last year. Total pond counts for the U.S. and Canada combined were 6.3 million, which is 12 percent below the 2014 estimate of 7.2 million and 21 percent above the long-term average.
“An early spring balanced with poorer habitat conditions was apparent in this year’s survey,” DU Chief Conservation Officer Paul Schmidt said. “In addition to reduced precipitation over the winter and early spring, we have lost critical nesting habitat with the decrease in Conservation Reserve Program lands and continuing conversion of habitat to agricultural production across the U.S. prairies. Fortunately, these conditions had minimal impacts on this year’s overall breeding bird numbers, but hunters should be concerned about these trends and what they might mean in future years.
“We have experienced good moisture in the prairies and liberal bag limits for more than two decades. Continuing habitat losses and drier conditions have the potential to change this scenario in the future.”
The spring surveys provide the scientific basis for many management programs across the continent, including hunting season dates and bag limits. The four flyway councils and the U.S. Fish and Wildlife Service Regulations Committee will meet later this month to recommend the season structure and bag limits for 2015-16.
Individual states will make their specific selections within a federal framework of season length, bag limits and dates.
