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

南非卡鲁多肉植物进一步退化的 15 年恢复能力

摘要 Tankwa Karoo 国家公园 (TKNP) 是著名的干旱生物群落的一部分，具有无与伦比的多肉植物多样性。该公园一直受到人为压力的影响，例如近期气候变化带来的严重放牧。本研究利用降雨和卫星数据调查了 2000 年至 2014 年间六种植被类型的植被生产力变化。公园大致分为低海拔平原 (316 m)，雨量较少，地形较潮湿，海拔较高 (1640 m)。长期降雨量从高原地区的 265 mm y-1 到平原地区的 100 mm y-1 不等。从低地到高地，NDVI 也相应显着上升（p
