Anolis ventrimaculatus is listed as Near Threatened due to this species having an extent of occurrence of approximately 22,600 km2, it being found in less than ten locations, and its habitat being in continuing decline because of wood extraction and agriculture (it almost qualifies as Vulnerable under criterion B1ab(iii)). Monitoring of this species and its habitat should be carried out because A. ventrimaculatus may qualify for a threatened category in the future if present pressures continue.

Geographic Range [top]

Range Description:This species is known from the high altitudes of the Pacific slopes of the western range of the Colombian Andes, including the basin of the River Murri, from the states of Valle de Cauca, Antioquia and Choco. It is found between 1,300 and 2,500 m above sea level and the area in which it is distributed is approximately equal to 22,601 km2.

Threats [top]

Major Threat(s): It is likely that this species is being impacted by habitat destruction and loss in some areas of its range. The montane forests of the Cauca Valley are severely fragmented and it is reported that between elevations of 1,000 and 2,000 m above sea level, most of the forest has disappeared and only scattered remnants remain. Many of the forest fragments are protected, however, the higher elevation forests in some areas are still being exploited for timber and other forest resources (WWF 2001a).

The forests of Chocó are also suffering from habitat loss due to deforestation. Although these forests only represent one-sixth of Colombian forests, they supply more than half of the wood in the country. Other causes of habitat loss in the area include industrial development, mining and illegal growing of coca (WWF 2001b).

Conservation Actions [top]

Conservation Actions: There are no known species-specific conservation measures in place for this species. In places its distribution coincides with protected areas. Further research and monitoring of the population and its habitat status should be carried out.
