Ctenosaura hemilopha. The IUCN Red List of Threatened Species 2020

Abstract

The Baja California Spiny-tailed Iguana has a wide distribution in the southern portion of the Baja California peninsula, south of Comondú. They seem to be structured in small and restricted subpopulations, with low but evident migration between them. Their extent of occurrence is 35,960 km 2 . They are most common in the southern Los Cabos region and less abundant in the north. Iguanas have not been recently found in several locations with former records. Iguanas are primarily threatened by habitat destruction and predation by free-roaming domestic cats and dogs near semi-urban areas and the periphery of large cities. Populations in the north may experience fluctuations from severe and cyclic droughts. The overall population trend is unknown and estimated to be fewer than 700,000 adults. This species currently qualifies as Least Concern.
