The critically endangered Blue Iguana is globally unique to Grand Cayman. Urgent wide ranging conservation measures are vital if this Caymanian flagship animal is to be saved from extinction. This document is a detailed plan for such measures, developed by the IUCN Iguana Specialist Group in consultation with the Cayman Islands Government and the National Trust for the Cayman Islands. It covers the period 2001 to 2006, and will be implemented by the National Trust in collaboration with local and international partners.
