The American Migratory Bird Hunting and Conservation Stamp, or Duck Stamp, is a form of licensure issued by the Federal Government for waterfowl hunters. Why do physical stamps act as licensure to hunt waterfowl on both public and private land in the United States?

The duck stamp has been well-documented in conservation communities as a resource which has made significant positive impacts on the environment.

Physical Properties Of Tar Sand Tailings That Influence Their Ability To Sustain Plant Growth, Timothy Cole

The mining of bituminous sandstone rock for the purpose of extracting bitumen has created a need for reclamation. One such mine is located in northern Logan County. Their mining operation involves removing large sections of sandstone, which is impregnated with bitumen, and crushing it to sand-sized material. The sand-sized material is then mixed with organic solvents which extract the bitumen. Once separated, the bitumen is stored for future refinement and the spent sand is stockpiled for later disposal.

The spent sands or waste material are referred to as tar sand tailings. These tailings have particular properties which make reclamation efforts …
