| Justification: Drimiopsis pusilla is known from only one small area, and based on its very restricted area of occupancy and extent of occurrence, has been assessed as Vulnerable under Criterion D2. Although the localities are within a forestry area, it occurs in areas maintained as firebreaks, and as it grows amongst rocks it has some protection from livestock grazing, so it is inferred that there are no current threats to this population. Date last seen: 2023 | |

| Geographic Range | |
|---|---|
| Range Description: | Drimiopsis pusilla is known from a small area within the Eswatini highveld, within a forestry plantation. |
| Countries: | Native: Eswatini; |
| Population | |
|---|---|
| Population: | This species was recorded from one locality in 1982, and again in 2000, but no details of population size were recorded. Although the area has not been revisited recently, it is presumed that the plant is still present in this locality, and that the population is stable. It was found again in 2023, in a nearby locality, with two small clusters of plants being observed. |

| Habitat and Ecology | |
|---|---|
| Habitat and Ecology: | This species was found in rocky grassland, vegetation type KaNgwane Montane Grassland (Gm16), in the grassland biome (Mucina et. al. 2018). |
| List of Habitats: | 4 Grassland 4.7 Grassland - Subtropical/Tropical High Altitude |
| Threats | |
|---|---|
| Major Threat(s): | The localities where this plant was found fall within a forestry plantation, but on an unplanted area, maintained as a firebreak. Provided that this area is not planted up, the current land use provides some measure of protection. There is livestock grazing in the area, but as the plants grow amongst rocks, this would protect them from grazing. |

| Conservation Actions | |
|---|---|
| Conservation Actions: | The localities where this plant was found fall within a forestry plantation, but on an unplanted area, maintained as a firebreak. Provided that the area is maintained as a firebreak area within the plantation and not planted up, this provides some measure of protection for this plant. Raising awareness with the plantation management of the presence of this species and the management actions to maintain it would assist with its conservation. |
