Justification
Listed as Least Concern since, although its currently known extent of occurrence is less than 5,000 km², it occurs in an area of extensive, suitable habitat which appears not to be under significant threat, it has a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Major Threats
The habitats of this species are not subject major pressure across most of its range. Only large scale settlement by people could threaten the populations of this species in Isla Tiburón, but this does not seem to be likely. Local people believe that this is a venomous lizard, but any resulting persecution is probably only a local threat.
