The population of the endemic Sister Island Rock Iguana (Cyclura nubila caymanensis) on Cayman Brac is in serious decline. These vegetarian lizards are an important part of the island's ecosystem. The reduction in population is the result of human activity on their habitat. Threats introduced by humans can only be eliminated by human action.
