Since approximately 1970, a combination of improved national protections, habitat conservation, and international trade regulations has enabled many crocodile populations to recover.1

Habitat Conservation

Conservation efforts have increasingly focused on providing economic incentives to local communities to protect crocodile habitats. For example, some programs in the Philippines provide payments to community members for each egg protected from collectors or nest destruction. These initiatives demonstrate that sustainable resource use can align human economic interests with the preservation of crocodilian environments.1

Trade Regulations

International trade is managed through the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES), which regulates the movement of species across borders to prevent overexploitation.23
* Permits and Restrictions: CITES categorizes species into appendices based on their threat level, requiring strict permits for trade to ensure it does not jeopardize a species' survival.23
* Sustainable Sourcing: Modern conservation models now incorporate regulated hunting, the collection of excess wild eggs, and commercial captive breeding. These methods supply international markets with legal skins—yielding roughly 800,000 to 1,000,000 skins annually—which helps reduce the pressure of illegal poaching on wild populations.14
