Freshwater crocodilians play keystone roles in wetland ecosystems while facing welfare threats from hunting and habitat loss.
Freshwater crocodilian welfare varies dramatically across species. American alligators have recovered spectacularly through protective legislation — a conservation success story showing what is possible with political will. Chinese alligators remain critically endangered with welfare concerns for the small wild population and the larger captive population in breeding centers. Caiman populations in South America face sustained hunting pressure for leather markets. Crocodilian welfare is also threatened by wetland drainage and pollution that reduces prey availability and habitat quality.
