| Justification: Cineraria ngwenyensis has an extremely limited distribution, its known population having declined drastically due to open cast iron ore mining from 1964 to 1977. The surviving population has a distribution with an estimated extent of occurrence of less than its area of occupancy of 4 km2. Based on this it has been assessed as Vulnerable under Criterion D2. There is a potential threat from resumption of mining activities in the area which could result in this species becoming Critically Endangered or even Extinct within a short period of time if the mining activities cause loss of habitat for this species. Date last seen: 1995 | |

| Geographic Range | |
|---|---|
| Range Description: | This plant has only been found in the Ngwenya Mine area within Malolotja Nature Reserve, in Eswatini. There are records from five localities, but two of these were from an area which was removed during the operation of Ngwenya Mine, and therefore no longer exist. |
| Countries: | Native: Eswatini; |
| Population | |
|---|---|
| Population: | According to Cron et. al. (2006), this species is very rare and restricted in distribution with small populations, currently known from three localities. |
| Population Trend: | Unknown |
| Habitat and Ecology | |
|---|---|
| Habitat and Ecology: | The species is found in the grassland biome,vegetation type KaNgwane Montane Grassland (Gm16) (Mucina et. al. 2018). According to Cron et. al. (2006), this species is found in the shade of rocks on mountain north-west facing spurs, near the summit of quartzite ridges. |
| List of Habitats: | 4 Grassland 4.7 Grassland - Subtropical/Tropical High Altitude |
| Threats | |
|---|---|
| Major Threat(s): | There is a possibility of further mining activities in the area, which could affect this species. However, if this species is restricted to the quartzite spurs, it is possible that mining activities could be conducted without the destruction of the habitat for this species. |
| List of Threats: | 3 Energy production & mining 3.2 Mining & quarrying |
| Conservation Actions | |
|---|---|
| Conservation Actions: | The entire distribution of this species falls within Malolotja Nature Reserve. However, in spite of this being a proclaimed protected area, it is possible that mining activities maybe resumed in the area, potentially affecting the remaining populations of this species. The plant is found on quartzite spurs, so it is possible that the mining activities might not directly be aimed at these areas, but there could be habitat loss due to mining infrastructure being established. |
| List of Conservation Actions: | 3 Species management 3.4 Ex-situ conservation 3.4.2 Genome resource bank |
