Lacey Act of 1900

The Lacey Act of 1900, or simply the Lacey Act (16 U.S.C. §§ 3371–3378) is a conservation law in the United States that prohibits trade in wildlife, fish, and plants that have been illegally taken, possessed, transported, or sold.

Introduced into Congress by Rep. John F. Lacey, an Iowa Republican, the Act was signed into law by President William McKinley on May 25, 1900. It protects both plants and wildlife by creating civil and criminal penalties for those who violate the rules and regulations. The law authorizes the Secretary of the Interior to aid in restoring game and birds in parts of the U.S. where they have become extinct or rare. It also regulates introduction of birds and other animals to places where they have never existed before.

The law is still in effect and has been amended several times.

In 1900, illegal commercial hunting threatened many game species in the United States. The original Act was directed at the preservation of game and wild birds, making it a federal crime to poach game in one state with the purpose of selling the bounty in another. The law prohibited the transportation of illegally captured or prohibited animals across state lines, and addressed potential problems caused by the introduction of non-native species of birds and animals into native ecosystems.

Today, the Lacey Act is used primarily to prevent the importation or spread of potentially dangerous non-native species. The Act also makes it unlawful to import, export, transport, sell, receive, acquire, or purchase in interstate or foreign commerce any plant in violation of the laws of the United States, a state, an Indian tribe, or any foreign law that protects plants.
