Management and Conservation

The work of the National Wildlife Property Repository supports efforts by the U.S. Fish and Wildlife Service and partners to combat wildlife trafficking and facilitate legal, sustainable wildlife trade. 

Wildlife Trade

Wildlife trade is the international or domestic trade of wildlife and products made from wildlife, including live wildlife and products like fur or leather fashion items, home goods, novelties like trinkets and souvenirs, musical instruments, traditional medicines, and much more. Trade in wildlife and wildlife products is a multi-billion-dollar business that spans the entire globe.

Legal Versus Illegal Wildlife Trade

The U.S. Fish and Wildlife Service works to facilitate a robust legal wildlife trade worth billions of dollars each year. By issuing import, export, and other types of permits and ensuring shipments of wildlife and products are compliant with regulatory laws, we help ensure that demand on wild populations is sustainable and that trade in wildlife does not adversely impact biodiversity.

When unregulated, wildlife trade can become unsustainable and cause harm to wild populations. Wild plants and animals may be overharvested to fulfill demands for live specimens or products, leading to declines in populations or increasing a species’ risk of extinction. Plants and animals that are endangered or threatened are particularly vulnerable to these impacts. Like  climate change climate change
Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climatic change, since the mid-20th century humans have had an unprecedented impact on Earth's climate system and caused change on a global scale.

 and habitat loss, illegal wildlife trade or “wildlife trafficking” can be a factor contributing to the loss of biodiversity.

The enforcement of laws regulating wildlife trade supports the long-term survival of plant and animal species. By complying with laws and regulations, importers and exporters of wildlife products help protect the health of wild populations, species, and entire ecosystems.

The United States' Role in the Illegal Wildlife Trade

  • The United States is a destination and transit point for trafficked wildlife and wildlife products. Much of the world’s trade – both legal and illegal – in wild animal and plant species is driven by U.S. consumers, originates in our country, or passes through our ports on the way to other nations.
  • The United States is also a supplier of native species that are in demand in other countries, including American ginseng, turtles, eels, and other species, some of which are illegally removed from the wild and exported.
  • The United States is committed to combating wildlife trafficking and the transnational organized crime attached to this illicit trade. Many U.S. Fish and Wildlife Service programs work to combat illegal trade in wildlife, including the Office of Law Enforcement and the International Affairs Program.

Laws Regulating Trade in Wildlife 

Several laws regulate the trade in wildlife and wildlife products in the United States and internationally. 

The Convention on International Trade of Endangered Species of Wild Fauna and Flora (CITES)

The Convention on International Trade of Endangered Species is an international treaty enacted in 1973 designed to ensure that international trade in animals and plants won’t threaten their survival in the wild. The U.S. Fish and Wildlife Service is responsible for carrying out the provisions under CITES for the United States, which is a signatory party along with 183 other countries around the world. Under CITES, species can be listed on three different “Appendices” according to how their current populations are doing in the wild and how much protection they need.  

  • Appendix I – Species are the most protected because they demonstrate the greatest threat of extinction.  Commercial trade in these species is prohibited.  Examples of Appendix I include tigers, rhinos, gorillas, and elephants.  
  • Appendix II – Species not under immediate threat of extinction but that warrant close monitoring in trade to ensure their numbers are sustainable. These species require permits and declarations for international trade.
  • Appendix III – Species have regulated trade by certain countries (Parties) and are listed to solicit the cooperation of other countries so that the trade in these species does not become unsustainable. 

A CITES permit issued by U.S. Fish and Wildlife Service may be required to import live or dead specimens, parts and products made from wildlife into the United States. Learn more about CITES permits from the U.S. Fish and Wildlife Service's International Affairs program

Endangered Species Act

The Endangered Species Act (ESA) was enacted in 1973 to protect populations of plants and animals that face imminent threat of extinction or endangerment in the future. Protection may also extend to the habitat of these species that is critical for their survival. Unless permitted, it is illegal to import, export, take, transport, sell, purchase, or engage in interstate and foreign commerce species listed as endangered or threatened. The ESA also implements CITES to protect species that are at risk due to wildlife trade. The number of species on the list changes as new species are added or delisted if population numbers are deemed to have passed the threat of extinction.  

Lacey Act

One of the first wildlife protection laws, The Lacey Act makes it illegal to have any wildlife that was taken in violation of international, federal, state, or Indian tribal law. First enacted in 1900, the Lacey Act prohibits interstate and foreign trafficking of wildlife. This covers all species protected under CITES Appendices. The National Wildlife Property Repository operates off funds generated by Lacey Act violation fees.  

Marine Mammal Protection Act

This act prohibits people from taking, importing, transporting, purchasing, and selling marine mammals and their products unless they obtain a special exemption. These mammals are protected in any ocean/sea or land controlled by the United States. Some examples of the species protected by this act include whales, dolphins, seals, sea lions, walrus, polar bears, manatees, and sea otters.  

Migratory Bird Treaty Act 

The Migratory Bird Treaty Act (MBTA) protects almost all native North American birds by prohibiting killing, capture, and possession for meat, pet or feather trade. MBTA is now an international agreement among the United States, Mexico, Canada, Russia, and Japan. Under the act, it is also unlawful to use the nests, eggs, and feathers even if they were naturally molted. Regulated hunting allows for the taking of game birds during established seasons.
