Hunters beware: President Obama's budget released Tuesday would hike duck stamp fees by $140 million over the next decade.

Federal duck stamps are issued by the U.S. Fish and Wildlife Service and required for anyone older than 16 who wants to hunt migratory waterfowl. A new $15 stamp must be purchased each year.

Among the myriad of increases in taxes and fees in Obama's fiscal 2015 budget request, the proposal seeks to raise an additional $14 million a year from hunters. The White House Office of Management and Budget projected that this would raise $140 million from 2015 to 2024.

The additional federal revenue raised by duck stamp sales is intended for funding conservation efforts.

The White House budget proposal did not say how much the stamps would cost after the increase, but a group of Democratic senators proposed a $10 increase in January, the first in 20 years.
