|Scientific Name:||Gallotia intermedia Barbadillo, Lacomba, Pêrez-Mellado, Sancho and López-Jurado, 1999|
|Taxonomic Notes:||This species is described by Hernández et al. (2000), but the name first appeared in Barbadillo et al. (1999).|
|Red List Category & Criteria:||Critically Endangered B1ab(v)+2ab(v) ver 3.1|
|Assessor(s):||Jose Antonio Mateo Miras, Valentin Pérez-Mellado, Iñigo Martínez-Solano|
|Reviewer(s):||Cox, N. and Temple, H.J. (Global Reptile Assessment)|
Listed as Critically Endangered because its Extent of Occurrence is less than 100 km2 and its Area Of Occupancy is less than 10km2, its distribution is severely fragmented, and although it is no longer experiencing a continuing population decline, it has only been increasing since 2001.
|Previously published Red List assessments:|
|Range Description:||This species was discovered in 1996 in the Macizo de Teno in the extreme northwest of Tenerife island, in the Canary Islands (Spain). It is now know from a small area of coastline in the extreme west of the island, and also from Montana de Guaza in the extreme south. It is believed that the species was once widespread throughout much of Tenerife.|

|Population:||There are 40 isolated populations along 9 km of coastline, totaling 500 animals. The population at Montana de Guaza is around 100 animals. It is increasing as a result of the control of introduced mammals.|
|Current Population Trend:||Increasing|
|Habitat and Ecology:||This species inhabits rugged terrain, with rocks and boulders, often found on small rock ledges with sparse vegetation. The species is presumed to have once occurred in a variety of habitats across Tenerife. The species is largely herbivorous. It is an egg-laying species.|
|Major Threat(s):||The main threat to this species is predation by feral cats and, to a lesser degree, by rats. It is presumed that the historical decline in this species was largely due to predation by cats. Several of the smaller populations, consisting of a few individuals, may be threatened by the effects of inbreeding.|
|Conservation Actions:||Measures to control access by cats to some of the remaining populations, such as fencing, have been implemented. A recovery action plan has been developed for this species. The species may still exist in other inaccessible parts of Tenerife, more field surveys are urgently needed. It occurs in at least one protected area.|
