Assessor(s)
A.P. Dold, C. McMaster & D. Raimondo
Justification
EOO 6484 km², six known locations are declining due to habitat loss to crop cultivation and overgrazing.
Distribution
Endemism
South African endemic
Provincial distribution
Eastern Cape
Range
Great Fish River Valley.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Eastern Upper Karoo, Southern Karoo Riviere, Fish Valley Thicket
Description
Sandy alluvial flats within floodplains.
Threats
This species' habitat (rich alluvial soil in floodplains) is highly suitable for agricultural crops. Three of the six recorded subpopulations have suffered extensive loss of habitat to crop cultivation and loss is continuing. Subpopulations in the former Ciskei have suffered declines as a result of habitat degradation due to livestock overgrazing and trampling. Subpopulations around Cradock fall within an area earmarked for large scale shale gas extraction, and could decline significantly in future.
Population
Population trend
Decreasing
Conservation
This species has recalcitrant seeds that are easy to cultivate and grow. Assisted colonisation into suitable but currently unoccupied habitat within its natural range is a possible conservation intervention.
