The current population of the La Gomera giant lizard consists of (2004) 90 individuals remaining in the wild, and a captive stock of about 44 animals. This species is now only known from two separate inaccessible cliffs 2 km apart, close to the Valle Gran Rey. The La Gomera giant lizard is thought to have once ranged throughout much of La Gomera and in many habitat types. Nowadays it is found in the Parque Rural de Valle Gran Rey, and the present range is less than one hectare and is restricted to dry cliffs with sparse vegetation.
