Ducks and wetlands are inseparable in the prairies. Hunters know this, bird watchers know this, wildlife managers know this, and most importantly people who manage the croplands and rangelands know this. The 1,746 tracts of native prairie within these upland-wetland complexes known as Waterfowl Production Areas are not the only lands purchased with "duck stamp" dollars. Considerable acreages have also been purchased in central and southern parts of the United States to provide staging, resting, and wintering areas for waterfowl. Since 1934, when "duck stamps" were first sold, nearly 2.5 million acres of waterfowl habitats have been acquired or taken under easement within the United States with revenue from these sales. By purchasing "duck stamps", more than 2.2 million people provide over $16.5 million in annual revenue. It is certainly gratifying to know that some of the remaining native prairie remnants in the Northern Great Plains are being reserved for the future with "duck stamp" dollars.
