Assessor(s)
N.R. Crouch, T.J. Edwards & L. von Staden
Justification
Plants at a single known location are potentially threatened by habitat loss and degradation, as well as medicinal plant collecting.
Distribution
Endemism
South African endemic
Provincial distribution
KwaZulu-Natal
Range
Mdumbeni River Valley near Muden.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Thukela Thornveld
Description
Shallow soils overlying dolerite in thornveld savanna.
Threats
There are currently no severe threats to this taxon, but nearby rural settlements are spreading. There is ongoing loss and degradation of natural vegetation within the river valley, mainly due to spreading crop fields, but the shallow soils where this taxon occurs may be unsuitable to cultivation. Overgrazing may cause some habitat degradation, and this taxon may be targeted for traditional medicine - typical Ledebouria ovatifolia is very popular in the ethnomedicinal plant trade (Crouch et al. 2007).
Population

The subpopulation at the type locality is suspected to be limited to several hundred mature individuals, but has not been counted (Crouch et al. 2007).


Population trend
Stable
Notes
This assessment includes Ledebouria pustulata S.Venter, which is the same taxon, but published later (A.J. Hankey pers. comm. 2014).
