Assessment Date
2007/12/29
Assessor(s)
L. von Staden
Justification
Restricted range (EOO 12 400 km²), recorded from 13-15 locations and continuing decline due to severe overgrazing, a threat that is likely to increase in future.
Distribution

Range
Western KwaZulu-Natal, from Mooi River to Bergville and north-eastwards to Vryheid.

Major habitats
Grassland, Savanna
Description
In grassland or thornveld, in hilly or gently undulating areas, often in rocky outcrops but can also occur in open grasslands and along road reserves.
Threats
The area where this species is found is mainly used as grazing lands, mostly for cattle but other livestock such as goats are also farmed. There is very little transformation in terms of crops and development (16% transformation, calculated using GIS). However, in some areas, especially communally owned land, such as between Bergville and Colenso and around Rorke's Drift, heavy overgrazing appears to be impacting on subpopulations of A. dominella (Craib 2005). In the Bergville district subpopulations are very small and restricted to sites among large boulders where they are protected from grazing and trampling, but is not found in other areas of suitable habitat at the edges of large rocky sheets or in open rocky grasslands (Craib 2005). Around Rorke's drift and Estcourt A. dominella is quite frequent in road reserves where rangelands are fenced, and appear to have declined within the grazing areas (Craib 2005). The Estcourt area is extensively under land claims, which will bring about large changes in the management regimes of rangelands when land is handed over to communities. As the land will be required to sustain much larger groups of people than before, the pressures, especially in the number of livestock kept on the land, is likely to increase significantly. A. dominella is dependent on fires to flower, but since grassland fires are also used to manage grazing quality, it is unlikely that fire exclusion is a threat. Craib's observations found some subpopulations to be lacking juveniles and seedlings. This may be either due to the poor seed set or to too frequent annual fires preventing the establishment of young seedlings (Craib 2005). Invasion by exotic black wattle, especially in the Estcourt district, is potentially threatening the habitat of some subpopulations of A. dominella (Craib 2005).
