Rationale
The threat status of Lalande's Black-winged Clonia (Clonia lalandei) is Vulnerable under criterion B1. Its extent of occurrence is relatively small (~15,000 km2), it has only been recorded in four locations, and the area, extent and quality of its habitat are expected to be in decline due to grazing pressure, cultivation, invasive alien plants and climate change. This species occurs within Golden Gate National Park and in Cathedral Peak, Drakensberg Nature Reserve, affording the species some protection against future changes.
Threats
This species occurs in temperate grasslands and woodland savannahs in regions which are under intensive grazing pressure by livestock and wildlife. A large proportion of the species' distribution range falls within protected areas, and these areas are threatened with tourist activities. The regions outside of the protected areas are intensively cultivated with non-timber crops and plantation forestry, and are often invaded by alien plant species such as Lantana spp., bugweed and other non-native weed species. Furthermore, climate change is already causing increasingly frequent extreme weather events in these regions, which is liable to drastically effect the distribution of grasses, the katydid's food plant.
Conservation
No specific conservation measures are in place for this species but it is known to occur in at least two protected areas, Golden Gate National Park and Cathedral Peak, Drakensberg Nature Reserve.
