Early Conservation Movement

Legislation and Treaties

Lacey Act enacted

Migratory Bird Treaty Act signed

Jul 3, 1918

This pioneering treaty between the United States and Great Britain (on behalf of Canada) protected migratory birds across international borders, making it illegal to hunt or sell many bird species and setting a precedent for cross-border species protection.

US Wilderness Act passes

Sep 3, 1964

The Wilderness Act designated millions of acres of undeveloped federal land as wilderness areas, protecting critical habitat from development and providing enduring refuge for countless plant and animal species.

Endangered Species Preservation Act enacted

Oct 15, 1966

The Endangered Species Preservation Act authorized the US Secretary of the Interior to list native species as endangered and provided limited funds for their protection, marking America's first comprehensive attempt at federal endangered species law.

Endangered Species Conservation Act strengthens protections

Dec 5, 1969

This act expanded earlier legislation to protect species threatened with worldwide extinction and prohibited importing illegally obtained endangered animals, paving the way for the landmark 1973 Endangered Species Act.

US Marine Mammal Protection Act passes

Oct 21, 1972

The Marine Mammal Protection Act prohibited the hunting, killing, and harassment of marine mammals such as whales, dolphins, seals, and sea otters in US waters, establishing a moratorium on their take regardless of population status.

Snail darter controversy begins

Aug 28, 1973

Discovery of the tiny snail darter fish halted construction of the Tellico Dam in Tennessee under the new Endangered Species Act, sparking a famous legal battle that tested the law's strength and reached the Supreme Court in 1978.

US Endangered Species Act signed into law

Dec 28, 1973

Signed by President Nixon after passing Congress nearly unanimously, the Endangered Species Act provided comprehensive protection for imperiled plants and animals, prohibiting harm to listed species and requiring recovery plans and critical habitat designation.

International Cooperation

IUCN Red List of Threatened Species launched

Feb 1, 1964

The International Union for Conservation of Nature introduced its Red Data Book in 1964, creating the world's most comprehensive inventory of species at risk of extinction and providing a scientific foundation for conservation priorities worldwide.

UNESCO World Heritage Convention adopted

Nov 16, 1972

The Convention Concerning the Protection of the World Cultural and Natural Heritage committed signatory nations to protecting sites of outstanding natural value, safeguarding critical habitats for endangered species across the globe.

CITES convention signed

Mar 3, 1973

The Convention on International Trade in Endangered Species of Wild Fauna and Flora regulated international trade in thousands of plant and animal species, becoming one of the most powerful tools against wildlife trafficking.

Convention on the Conservation of Antarctic Marine Living Resources

May 20, 1980

CCAMLR established an ecosystem-based approach to managing Antarctic fisheries, protecting krill-dependent species including penguins and seals and creating a framework for marine protected areas around Antarctica.

Key Facts

The Lacey Act of 1900 was the first major U.S. federal law protecting wildlife by prohibiting illegal trade of protected species.
The Endangered Species Act of 1973 is considered one of the strongest environmental laws, providing legal protection for threatened and endangered species and their habitats.
CITES (Convention on International Trade in Endangered Species), established in 1975, regulates international trade of over 38,000 plant and animal species.
The IUCN Red List, first published in 1964, remains the world's most comprehensive inventory of the global conservation status of species.
Conservation successes include the recovery of species like the bald eagle, which was delisted from the Endangered Species Act in 2007 after populations rebounded.
