The Dadra and Nagar Haveli Wildlife Sanctuary covers 91.39 square kilometres, or about 19% of the union territory's total area. The sanctuary provides a habitat for leopard ("Panthera pardus"), wildcat ("Felis silvestris"), striped hyena ("Hyaena hyaena"), fox ("Vulpes" spp.), golden jackal ("Canis aureus"), nilgai ("Boselaphus tragocamelus"), four-horned antelope ("Tetracerus quadricornis"), sambar deer ("Rusa unicolor"), and chital deer ("Axis axis"), and birds including black drongo, bulbul, kingfisher, egret, hoopoe, mynah, heron, and red jungle fowl. In 2014 an additional eco-sensitive area was designated in the 100-meter buffer zone around the wildlife sanctuary, with an area of 26.57 square kilometres.
