Justification
Erica vlokii has an extent of occurrence (EOO) of 1643 km², and an area of occupancy (AOO) of 76 km². This species occurs at five to seven locations and is declining due to too frequent fire and competition from alien invasive plants.
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range
This species is endemic to the mountains of the Western Cape, where it occurs in the Swartberg, Kammanassie and Outeniqua Mountains between Klaarstroom and George.
Habitat and Ecology
Major system
Terrestrial
Major habitats
South Kammanassie Sandstone Fynbos, South Swartberg Sandstone Fynbos, North Swartberg Sandstone Fynbos, North Outeniqua Sandstone Fynbos
Description
It occurs on slopes in arid fynbos.
Threats
This species has lost some habitat to timber plantations on the lower slopes of the Outeniqua Mountains in the past (about 8% of its habitat has been lost). Currently, this species is threatened mainly by spreading alien invasive plants, particularly on the northern aspect of the Paardeberg, as well as too frequent fires in the Camferskloof area.
Population

Field observations indicate that subpopulations are small. A continuing decline is inferred from ongoing habitat loss and degradation.
