H. wittebergensis is occasionally collected for the succulent trade - a collector was caught once with 500 plants. However, the impact of collecting is sporadic, and with this species being fairly common and most of its habitat inaccessible, collecting is not suspected to be causing severe enough declines to put this species at risk of extinction in the wild. Parts of the habitat is degraded due to overgrazing, but this seems to have little effect on the species (J.H. Vlok pers. obs.).

A narrow endemic, but fairly common in suitable habitat (J.H. Vlok pers. obs.), much of which is poorly explored and inaccessible. It is slow growing and difficult to keep in cultivation (Bayer 1982). Plants are cryptic and the few known records are likely to be an underestimation of the number of subpopulations/locations.

Population trend
An indisputably discrete species (Bayer 1982), not easily confused with any other species of Haworthia.
