Justification
Elegia fucata is a highly localized species, known from one location. It is potentially threatened by competition from alien invasive plants and too frequent fire.
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range
This species is endemic to the upper northern slopes of the Riviersonderend Mountains at Jonaskop in the Western Cape.
Habitat and Ecology
Major system
Terrestrial
Major habitats
North Sonderend Sandstone Fynbos
Description
It occurs in seeps and along streams, often in deeper soil, 1500-1600 m.
Threats
This species is a reseeder, which means that it is killed by veld fires and regenerates from soil-stored seeds. Too frequent fires could quickly lead to a depletion of soil seedbank, and failure of post-fire recruitment. The southern slopes of the Riviersonderend Mountain just below the summit of Jonaskop is densely infested with uncontrolled alien invasive pines. Recently the pines have started spreading onto the northern slopes, and could potentially outcompete the small, localized population of this species in future.
Population

This species is a highly localized habitat specialist, and is locally common in seeps and along drainage lines, but absent from dry ridges. It possibly also occurs in similar habitat elsewhere on the Riviersonderend Mountains, and its potential distribution range has not yet been fully explored (Linder 2011). The population is not currently declining, but this species could rapidly become Critically Endangered or even extinct if potential threats were to materialize.
