The Hantam-Roggeveld area is centered on the town of Calvinia and encompasses both the Bokkeveld and Roggeveld escarpments.
Some 2500 species of plants occur in the Hantam-Roggeveld, of which about 10% are endemic. The rugged slopes and cool highlands include a wide range of species characteristic of the interface between the renosterveld and Succulent Karoo.
As with the Namaqualand Uplands, conserving the cooler areas is an essential strategy for maintaining the unique diversity of the hotspot in the face of climate change. Additionally, due to relatively low levels of transformation in this priority area, there are excellent opportunities to include viable populations of Black Rhinoceros and upland-lowland seasonal migration routes for animals, especially Springbok.
The total plant species tally in this 86,600-hectare area is 1,767, of which 357 are Succulent Karoo endemics and 173 are Red List species.
