Which federal action helped to boost wildlife conservation funding in the United States?

The Pittman-Robertson Act, also known as the Federal Aid in Wildlife Restoration Act, significantly boosted wildlife conservation funding in the United States by implementing an excise tax on firearms, ammunition, and equipment used for hunting. This funding mechanism diverts revenue to state wildlife agencies for various conservation efforts, including habitat restoration, management of wildlife populations, and research initiatives.

The Act also emphasizes the importance of hunters and anglers in supporting conservation financially, enabling states to bolster their wildlife resources and engage in educational programs aimed at promoting responsible outdoor recreation. The program has been instrumental in maintaining and enhancing wildlife populations across the country since its inception in 1937, making it a cornerstone of wildlife management and conservation funding in the U.S.

In contrast, the other choices primarily address specific aspects of conservation, such as creating national parks or protecting endangered species, but do not have the same direct financial impact on wildlife conservation funding as the Pittman-Robertson Act does.
