Tephrosia natalensis H.M.L.Forbes subsp. pseudocapitata (H.M.L.Forbes) Schrire
|Tephrosia pseudocapitata H.M.L.Forbes|
Status and Criteria
Endangered A2c; B1ab(iii)+2ab(iii)
|L. von Staden|
|A range-restricted taxon (EOO 185 km²), known from two, possibly five remaining locations. A population reduction of at least 50% over the past three generations is inferred from habitat loss across its range, and it continues to decline due to ongoing habitat loss and degradation.|
|South African endemic|
|KwaZulu-Natal Midlands near Greytown.|
Habitat and Ecology
|Midlands Mistbelt Grassland, KwaZulu-Natal Highland Thornveld|
|Nearly 70% of this taxon's habitat is already irreversibly modified, predominantly due to the establishment of exotic timber plantations. There is still sporadic ongoing expansion of timber plantations, but the main threats to remaining subpopulations of this taxon are habitat loss to urban expansion and spreading rural settlements, overgrazing of small remaining grassland fragments, and spreading of alien invasive plants.|
A population reduction of at least 50% is inferred from nearly 70% habitat loss over three generations - this taxon is a long-lived resprouter with an estimated generation length of 30-50 years. It has a very limited distribution range, and few subpopulations are known to remain, although more field surveys are needed in areas where it is known from historical records. It continues to decline due to ongoing habitat loss and degradation.
