Assessor(s)
O.E. Curtis, C.H. Stirton, M. Muasya & D. Raimondo
Justification
This long-lived, slow-growing resprouter (generation length at least 40 years) is estimated to have declined by at least 30% due to habitat loss and degradation since 1940.

Bredasdorp to Heidelberg.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Eastern Ruens Shale Renosterveld, Ruens Silcrete Renosterveld, Potberg Ferricrete Fynbos, Swellendam Silcrete Fynbos
Description
Flats with white quartz pebble patches in Eastern Rûens Shale Renosterveld.
Threats
Aspalathus quartzicola is threatened by ongoing habitat loss and degradation due to agricultural expansion. Although its specific habitat is not suitable to cultivation, much of it has been ploughed in the past, and subsequently left fallow (O.E. Curtis pers. obs.). Degradation continues mainly due to severe overgrazing of small remaining remnants.
Population

This species is long-lived and slow growing, and a past population reduction of at least 30% is estimated based on the extent of habitat loss and degradation within its range.
