Threats [top]
Major Threat(s): The specific threats to this species are unknown. Disturbance through tourism and invasive alien species are potential threats, but it is not clear if any of these is impacting on this species. Furthermore, agricultural expansion could also cause changes in the microclimate in the area where this species grows. The area where it is found is highly managed.
Conservation Actions [top]
Conservation Actions: This species is found in the area of a royal project, which means that the area might be protected to some extent (it is unlikely that cement factories will be established there), however, the area surrounding the limestone can still be cultivated, which might affect the microclimate. The area where this species is found is managed, but the staff working there are unaware which species are native and should be protected.
