NEW ORLEANS, La. (AP) - The Interior Department is selling a new duck stamp envelope to raise money for conservation in the aftermath of the Gulf oil spill.

Duck stamps are more formally known as the Federal Migratory Bird Hunting and Conservation stamp. They are pictorial stamps that can be bought in order to help with wetland conservation. 98 cents of every dollar made goes to the purchase or lease of wetland habitat in protection for the National Wildlife Refuge System.

All migratory bird hunters must buy a duck stamp along with state licenses and permits.

The new duck stamp envelopes were unveiled Tuesday. They feature a silk rendering of a photograph of St. Marks National Wildlife Refuge on the Gulf Coast of Florida, as well as the 2010-2011 federal duck stamp.
They sell for $25, ten dollars more than a regular duck stamp. The extra ten dollars will be used to buy land for national wildlife refuges on the Gulf Coast.
