Romulea namaquensis M.P.de Vos
Higher Classification
Monocotyledons
Family
IRIDACEAE
Synonyms
Romulea namaquensis M.P.de Vos subsp. bolusii M.P.de Vos
National Status
Status and Criteria
Near Threatened B1ab(ii,iii,v)
Assessment Date
2007/01/25
Assessor(s)
D. Raimondo
Justification
EOO 620 km², known from nine locations, of which five occur in areas where crop cultivation takes place so a continuing decline is inferred. Due to there still being habitat available within this species range it is likely that there are around 15 locations.
Distribution
Endemism
South African endemic
Provincial distribution
Northern Cape
Range
Steinkopf to Kamiesberg.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Succulent Karoo
Description
Sandy or stony soil, in succulent karoo shrubland.
Threats
Threatened by ongoing habitat loss to crop cultivation - at least 70% of this species' habitat on granite soils is already transformed. Remaining subpopulations, particularly those on small fragments are further declining due to heavy grazing associated with overstocking.
