Abstract

Soutpansberg Mountain range is one of the main biodiversity hotspots in South Africa and it is located in Limpopo Province. It possesses high diversity of flora and fauna. Communities surrounding this mountain have long benefited from the ecosystem services that the area provides. It is of importance to determine the threat status of plant species endemic to this mountain range that has been a great source of ecosystem services. Twenty-two endemic vascular plant species of the mountain range have been identified. In this study we use the South African National Biodiversity Institute (SANBI) current 2017 version Red List categories to determine the threat status of plant species endemic to Soutpansberg Mountain range. SANBI is the national body in South African that is responsible for national threat assessment for plant and animal species and they also provide data to IUCN (International Union ofC onservation of Nature) on threat status of plant and animal taxa found in South Africa. We calculated the categorical percentages of threat status of endemic vascular plants species of Soutpansberg Mountain range and the threats these plant species are facing were gotten from SANBI Red List. This study showed that over 50% of the plant species endemic to this area are of conservation concern meaning they deserve conservation attention. Majority of threats are due to anthropogenic pressure. This implies that the endemic flora of this region is facing risk of extinction. This study recommends protection of all the endemic plant species of this mountain range in order to prevent theirf uture extinction.

Highlights

  • N the threats these plant species are facing were gotten from South African National c Biodiversity Institute (SANBI) Red List

  • SANBI is the national body in South Africa that is responsible for national threat assessment of plant and animal species

  • We used the threat of these species from the SANBI Red List to determine the percentages of species that are threatened and not threatened within Soutpansberg Mountain range and the ones that are of conservation concern

Summary

Materials and Methods

The list of the 22 endemic vascular plant species on Soutpansberg Mountain range were obtained from Hann.[18] The threat status of these species was obtained from the current 2017 version of SANBI Red List. We used the threat of these species from the SANBI Red List to determine the percentages of species that are threatened and not threatened within Soutpansberg Mountain range and the ones that are of conservation concern. Percentages of endemic plant species facing each threat found on SANBI Red List were calculated. This is to quantify the species facing different kind of threats and to determine the prominent threats of the endemic vascular plant species on this mountain range.
