Ctenosaura pectinata. The IUCN Red List of Threatened Species 2020

Abstract

The Guerreran Spiny-tailed Iguana is widely, but unevenly distributed throughout western México to the southern part of the Tehuantepec Isthmus in Oaxaca. In this area, 36% of their habitat has been converted to large- and small-scale agricultural, ranching, and urban uses. It is suspected that there has been a decline in the iguana population correlated with this habitat loss; the majority of this habitat loss occurred more than three generations ago. The population seems to be structured in isolated subpopulations, with very large concentrations in some areas and absent in others. There are no data available on the population trends or fine-scale density and size information. They are hunted extensively for human food, medicinal uses, and handicrafts, from wild and cultivated sources. Density has been observed to be over 100 times greater in areas where they are not hunted. The level of consumption is not fully known but estimated to be in the tens of thousands annually....
