Justification
Ledebouria monophylla is a widespread (EOO 45 208 km²), but rarely recorded species that is possibly overlooked, as it is easily confused with other species. It is declining due to habitat loss and degradation across its range, but it is not yet considered in danger of extinction.
Distribution
Endemism
South African endemic
Provincial distribution
KwaZulu-Natal, Limpopo, Mpumalanga
Range
Wolkberg to the Mpumalanga Drakensberg Escarpment and the KwaZulu-Natal Drakensberg foothills and Midlands.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Grassland
Description
Deep, humus rich sandy soils derived from sandstone and quartzite in montane grasslands near streams.
Threats
Ledebouria monophylla has lost much of its habitat to timber plantations across its range in Limpopo, Mpumalanga and KwaZulu-Natal. Timber plantations are no longer expanding significantly, and in Mpumalanga most of its remaining habitat is protected. It is however threatened in many places by unmanaged, spreading alien invasive plants and habitat loss to mining (M. Lotter pers. comm.). In Limpopo and near Graskop it is also threatened by habitat degradation due to livestock overgrazing.
Population

This species is known best from the Mpumalanga Escarpment between Ohrigstad and Sabie, where there are several known subpopulations, consisting of up to 200 individuals (Venter 1993). Venter (1993, 2008) included a single record from KwaZulu-Natal in his treatment of this species, but since then more observations of this species in KwaZulu-Natal have been recorded (A.J. Hankey pers. comm.). This species is superficially similar to L. sandersonii, and it is possibly overlooked in KwaZulu-Natal.
