Range Description

Learn more about this article

The Cape Sengi is endemic to South Africa (Corbet and Hanks 1968; Skinner and Chimimba 2005). Although most distribution maps show it as having two disjunct areas of occurrence, recent data indicate that it is continuously distributed (Stuart and Stuart 1991; Friedman and Daly 2004). It has not been recorded in Namibia, and is not suspected to occur north of the Orange River.

Justification
This species is listed as Least Concern. Although this species is not abundant, it is widespread in suitable habitats over an area greater than 130,000 km². Because it occupies rocky habitats that are arid and will not support most development, there are no known threats to the large area occupied by the Cape Sengi. Areas close to rivers or reliable sources of water may have been developed, or may be developed in the future, as urban areas. For example, alluvial areas along rivers in the Cedarberg Mountains of South Africa have been developed for agriculture, but these habitats are not usually occupied by Cape Sengis, and these areas are relatively small compared to the overall distribution of this species. Small areas also may be impacted by intensive goat and sheep grazing as well as mineral extraction activities, but these types of disturbances are confined to small areas compared to the overall distribution of the species. Past, current and future development in this region of Africa is not expected to have a significant impact on this sengi or its habitats.

Population

Population
The species is not considered abundant, but it is widespread in suitable habitats and locally common. Current population trends are not known, but there is no reason to believe that E. edwardii numbers are increasing or decreasing significantly due to any factors other than natural variation in environmental conditions in the rocky and arid environments where they occur.

Major Threats
There are no known major threats to the species. Habitat modification to relatively small areas may occur near rivers and human population centres due to small-holder and industrial agriculture, mineral extraction, and urban development, however, these are not considered major threats to the current population.
