Justification
Leucospermum wittebergense is widespread, common and not in danger of extinction. It is therefore assessed as Least Concern.
Distribution
Endemism
South African endemic
Provincial distribution
Eastern Cape, Western Cape
Range
This species is widespread in the mountains of the southern Western Cape, extending to the Eastern Cape. It occurs from the Witteberg near Touwsrivier eastwards to the Kouga Mountains and Grootrivier Mountains in the Steytlerville district.

Description
It occurs predominantly on arid, rocky sandstone or quartzitic slopes, more rarely on sandstone-shale ecotones, 300-1800 m. Mature individuals are killed by fires, and only seeds survive. Seeds are released after ripening, and dispersed by ants to their underground nests, where they are protected from predation and fire. It is pollinated by birds.
Threats
As a reseeder, Leucospermum wittebergense is potentially vulnerable to too frequent fires, which can cause local extinctions if fires repeatedly kill individuals before they are reproductively mature. Field observations noted too frequent fires occurring in the Swartberg and Baviaanskloof, but no loss of subpopulations have yet been recorded. It is also potentially threatened by competition from alien invasive plants at some localities in the Swartberg, Outeniqua Mountains and Baviaanskloof.
Population

This species is common across its range, occurring in large subpopulations. As there are no severe threats, the population is not suspected to be declining.
