Justification

The Nolasco Spiny-tailed Iguana is known only from the island of San Pedro Nolasco, Mexico. Iguanas are found throughout the approximately 3 kmÂ² island. Though this iguana has a very restricted range, the population size is not known to be decreasing or subject to extreme fluctuations. However, there are a number of threats and potential future threats, which, once these start to cause any declines, the species would immediately qualify for a Critically Endangered listing given the small size of the area and it essentially being a single location for most of the threats listed.
