Justification
Erica trichophylla is a highly localized species, with an extent of occurrence (EOO) of 45 km². It is known from two locations and is threatened by rapidly spreading, unmanaged alien invasive plants.
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range
This species is endemic to the Riviersonderend Mountains in the Western Cape.
Habitat and Ecology
Major system
Terrestrial
Major habitats
South Sonderend Sandstone Fynbos
Description
It occurs on middle to upper slopes in montane sandstone fynbos.
Threats
Escaped pine seedlings from commercial timber plantations on the lower south slopes of the Riviersonderend Mountains have spread rapidly, as well as significantly increased in density over the past 15 years, and in some places there is now 100% cover. Pines are now present within one of the subpopulations, and is likely to spread to the second subpopulation in the near future.
Population

This is a locally abundant species, known from two subpopulations within a small area. The threat of competition from alien invasive pines is increasing, and the population needs to be monitored - it is very likely to continue to decline if pines are not cleared urgently.
