Assessor(s)
N.A. Helme, P. Goldblatt, D. Raimondo & D. van der Colff
Justification
A rare, localized habitat specialist (EOO and AOO less than 5.8 km²), only known from two locations where habitat loss to damming of streams was a past and remains a potential future threat.
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range
Piketberg.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Piketberg Sandstone Fynbos
Description
Seeps and streams that remain wet until December, always in rocky sites on higher slopes.
Threats
The habitat of this species is vulnerable to flooding as a consequence of damming of mountain streams. A nearby stream was dammed some years ago, destroying about three hectares of streamside habitat (N.A. Helme pers. obs.). Further habitat loss to dam construction remains a potential threat.
