Heuningkaroo (a)
National Status
Status and Criteria
Least Concern
Assessment Date
2017/01/26
Assessor(s)
D. Raimondo & L. von Staden
Justification
A widespread species that is not currently in danger of extinction, but may decline in future, should planned shale gas extraction go ahead.
Distribution
Endemism
South African endemic
Provincial distribution
Northern Cape, Western Cape
Range
Roggeveld and Nuweveld escarpments to Matjiesfontein.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Fynbos, Nama Karoo, Succulent Karoo
Description
Upper south-facing slopes, 1000-1700 m.
Threats
This species is potentially threatened by habitat loss to infrastructure development related to shale gas extraction. Most of its range falls within an area earmarked for shale gas extraction, but the potential extent of the impact of the population is at present too uncertain to make estimations of potential future population reduction.
Population

J.P.H. Acocks, in his surveys of the vegetation of South Africa in the 1950s and 60s, found this species to be widespread and common across the Roggeveld and Nuweveld escarpments, but noted that plants are heavily grazed. Current population status and trends are not known.
