Ctenosaura defensor is known only from the northern portion of the Yucatán Peninsula, Mexico. Extent of occurrence is less than 20,000 km² and area of occupancy is less than 2,000 km². Number of locations is not known, however, the population is severely fragmented. Habitat is fragmented and is declining in quality. The population is also threatened by illegal collecting for the international pet trade. As a result of both these threats, the population is predicted to decline by at least 30% over the next ten years. Current population size is not known, but is thought to be several thousand.
