Assessment Information [top]

Red List Category & Criteria: Endangered B2ab(i,ii,iii,iv) ver 3.1
Year Published: 2010
Date Assessed: 2007-04-01

Chlorolestes apricans qualifies for an Endangered assessment due to the small number and small size of subpopulations, several of which have been lost between 1975 (when the species was known from ten sites) and 2000 (when it was known only from two sites) through habitat loss and modification. The population is expected to decline over the next ten years if habitat loss and degradation continues. Current area of occupancy is less than 500 km² and there is continuing decline in range, habitat and population size. It is therefore listed as Endangered.

Geographic Range [top]

Range Description:In 1975, this species was known from ten sites (Wilmot 1975), whereas in 2000 it was known from only two, showing a decline in extent of occurrence and area of occupancy, as well as decline in extent and quality of suitable habitat. It is currently known only from the Kubusi (near Stutterheim) and the Thorn River, eastern Cape, South Africa.
Countries occurrence:
South Africa (Eastern Cape Province)
Additional data:
Estimated area of occupancy (AOO) - km2:0-500
Number of Locations:2

Population [top]

Population:It is estimated that no more than 1,000 adults (per generation) exist, and even this may be a generous estimate. Population trends are unknown.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The species inhabits clear, shallow, rocky streams with riffles and glides and with an abundance of long grass, herbs and indigenous overhanging bushes (used as oviposition sites).
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): Populations are severely threatened by cattle trampling stream banks and the synergistic effects of shading of the habitat by the alien invasive tree Acacia mearnsii. Further adverse synergistic effects include detergent entering the streams at Stutterheim, and possibly also the effects of direct predation from rainbow trout Oncorhynchus mykiss.

Conservation Actions [top]

Conservation Actions: This species is not known from any protected areas. Surveys on further localities are urgently required. Removal of Acacia mearnsii should continue. Liaison with local farmers is essential so that cattle may enter streams at certain points only, fencing off other areas of the stream.
