Booby Pond and Rookery is located on the southern coast of Little Cayman. The Site mostly comprises a seasonally flooded, eutrophic, brackish-hypersaline lagoon system, separated from the sea by a narrow coastal beach ridge. The lagoon is irregularly fringed by mangrove communities. It is a representative example of a landlocked, mangrove-fringed saline lagoon system and supports several globally threatened animal species, including the endemic Sister Islands rock iguana (Cyclura nubila caymanensis) and Parker’s dwarf boa (Tropidophis parkeri), which are both critically endangered. The Site contains a breeding colony of over 5,000 adult red-footed boobies (Sula sula). In addition, its shrubland features a diverse range of plants of which several are threatened endemic or near-endemic species. Human activities include tourism and recreation. The Site faces several threats, including pressure from residential and commercial development, disturbance of breeding birds, and predation of native animals by feral cats and rats.
