Justification | Staavia pinifolia is a very rare and very poorly known species. It is suspected to have a small population, but the extent of its distribution range and number of existing subpopulations remains unknown. More field surveys as well as taxonomic study is required to enable an assessment of its risk of extinction. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Cape Peninsula, Drakenstein Mountains and Ouhangsberg between Villiersdorp and Robertson. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Fynbos |
Description | Rocky crevices on sandstone slopes. |
Threats |
This species is poorly known and threats to the population are poorly understood. On the Cape Peninsula it is potentially threatened by too frequent fire and competition from alien invasive plants. |
Population |
This species is extremely rare on the Cape Peninsula, where it occurs in very small, isolated clumps of just a few plants. There are a number of collections from the Cape Peninsula dating from the 1930s-1960s, but recent observations are scarce. There are possibly <50 plants on the Cape Peninsula (N.A. Helme pers. comm.). Elsewhere in its range it remains poorly known. There is only one old collection from the Drakenstein Mountains, and one from the Ouhangsberg, where the subpopulation was reported to consist of fewer than 50 plants. The species may be overlooked and collections may remain misidentified due to taxonomic confusion. The current population trend is not known, but the species is possibly declining.
