Abstract The Tankwa Karoo National Park (TKNP) is part of a renowned arid biome with unrivaled diversity in succulents. The park has been subject to anthropogenic pressures such as heavy grazing with climate change a recent threat. This study investigated changes in vegetation productivity between 2000 and 2014 across six vegetation types using rainfall and satellite data. The park is broadly divided into a plain at low altitude (316 m) receiving less rain and a wetter, higher terrain (1640 m). Long-term rainfall varied from 265 mm y-1 in the highland areas to 100 mm y-1 in the plains. There was a significant corresponding rise in NDVI from the low to the highlands (p
