Canadian Duck Populations are on the Increase
Nothing is certain in the natural world, and nothing should be taken for granted, but the fall waterfowl-hunting picture is becoming clearer and clearer: It could be a darn good season.
According to the
U.S. Fish and Wildlife Service, which released its much-awaited Waterfowl
Breeding Population and Habitat Survey the second week of July, the fourth
highest Canadian pond count on record helped propel the breeding populations of
three duck species northern shovelers, redheads and canvasbacks to all-time
highs and pushed the green-winged teal population to its second-highest level on
record. Blue-winged teal, responding to improved wetland conditions in the U.S.
and Canada, achieved their third highest breeding population ever.
May ponds
across the surveyed area were at about 7 million, a 15 percent increase from
2006 and 44 percent higher than the long-term average, and the total-duck
breeding population climbed 14 percent to 41 million birds. And mallards the
King of Ducks rose 10 percent to slightly more than 8 million. Of the other
species in the survey, gadwall climbed 19 percent to 3.4 million breeding birds,
wigeon jumped 29 percent to 2.8 million, green-winged teal rose 13 percent to
2.9 million, blue-winged teal were up 14 percent at 6.7 million, shovelers rose
24 percent to 4.5 million, redheads climbed 10 percent to just over 1 million,
scaup bounced 6 percent from year's record low to 3.5 million and canvasbacks
jumped by a surprising 25 percent to 865,000.
One caveat: pintail
numbers, which dipped to 3.3 million despite a 111 percent jump in the eastern
Dakota survey area, dropped yet again, raising questions with duck biologists.
What's abundantly clear from
the month-long ground and air survey (more on the survey below) is that the
Conservation Reserve Program (CRP) in the breeding ground states of the North
and South Dakota and parts of Montana is producing ducks particularly hunter
favorites like mallards and pintails for hunters nationwide.
According to research conducted by the U.S. Fish and Wildlife Service, CRP,
which has numerous fish and wildlife habitat benefits, is responsible for
putting roughly 2 million additional ducks in the air each year.
And that's why hunter-conservationists need to contact their elected officials
to ensure CRP is not only reauthorized in the next federal Farm BillΠthat1s all
but certain, but here again you can't take anything for granted but funded in
way that makes the program more attractive to farmers and landowners, many of
whom are taking their lands out of CRP because of soaring corn prices. Contact
your lawmakers today, and tell them to support CRP.
Question: Did you ever wonder how federal officials count the number of ponds
and ducks? It seems like an impossible exercise, doesn't it?
The spring breeding survey, the
world's largest wildlife inventory yes, the world's largest wildlife survey,
which turned 50 in 2005 takes place in the air and on the ground.
Flying in single-engine planes at 100
miles an hour just 150 feet off the ground, pilot biologists document the
species and sex of ducks observed on one side of the plane while an observer in
the passenger seat records ducks and counts and types wetlands by size and
permanence no easy task.
Their observations are captured by an
onboard computer that's interfaced with a Global Positioning System (GPS) unit
that merges the information about ducks and wetlands with the exact coordinates.
After the air campaign, "ground-truthing"
begins. Teams of ground observers search 18-mile segments of the transects,
counting birds that may have been missed by the flight crew. The ground crew's
observations are used to arrive at what's called a "correction factor" that's
used to produce the most accurate possible numbers.
It's a far cry from primitive
data-collecting techniques employed by the pioneers of the spring survey. Those
legendary scientists identified the transects that are basically the same as
those being flown today.
Each spring the pilots fly some 45,000 miles
across roughly two million square miles covering the Dakotas, western Montana,
Alaska, the Yukon and the prairie provinces of Alberta, Saskatchewan and
Manitoba.
Unfortunately, the service has discontinued other
long-term surveys because of lack of funding, as well as cut several important
positions across pretty much every U.S. region. One of those "lost" surveys is
the July survey that records July ponds and brood indexes across the breeding
grounds.
That said, the spring breeding population and habitat
survey is one of the great success stories in wildlife management. Now we just
have to bring back the July survey so biologists and others can better access
duck production on the breeding grounds.
