Droughts are a common phenomenon in this semi-arid savanna. The plants of this region have adapted to survive extreme rainfall variability and drought events. This adaptability and the inherent resilience (i.e. the ability to recover to its original state) of vegetation in the southern Kalahari enables it to recover quickly when conditions become more favourable. Droughts in the region are, however, predicted to increase in frequency and intensity due to global climate change. The associated increased aridity may also push many species beyond their tolerance threshold, leading to permanent shifts in vegetation dynamics. The aim of this study was to determine: (i) the growth vigour, cover abundance and productivity of herbaceous plant functional groups during the drought, (ii) the rate of post-drought recovery and (iii) the relative resilience and resistance of herbaceous plant functional groups. The drought affected all herbaceous plant functional groups as growth vigour, cover abundance and productivity were extremely low during the drought. All herbaceous growth started to recover post-drought but differed in their rate of response. Annual herbaceous species were found the be remarkably resilient to drought while perennial grasses were less resilient but far more resistant to the drought. Despite the resilience and rapid recovery of herbaceous growth, compositional changes post-drought were limited due to the degraded condition of the rangeland prior to the drought.

As predicted, warthog mainly consumed grass at both sites (AMC – 87.4%, GFRNR – 88.5%), eating few woody plants, succulents, and forbs. <em>Cynodon dactylon</em> was the most consumed species in AMC, in GFRNR this was <em>Eragrostis curvula</em> and <em>Cymbopogon pospichilii</em>. Our ability to predict the diet between sites was constrained by variation in the plant species consumed. We found strong relationships between the consumption of preferred plant species at AMC and their consumption at GFRNR.

The annual temperature changes near the Earth's surface, using ERA5 data, showed a significant increase of 1.5 °C in average temperature over the past thirty years.

For MODIS data validation, two methods of overall accuracy and the Kappa coefficient were used with 93% and 85% of accuracy. While the annual snowfall and volume have remained relatively stable over the past 20 years, the findings indicate a decreasing trend of snow cover during warmer months (summer) due to rising air temperatures. The findings show a strong negative correlation coefficient of −0.8 between snow cover and annual average temperature. The results indicate a 30% decrease in summer snow cover compared to the spatial extent of two decades ago. The rapid snowmelt poses a significant threat to permanent glaciers in the region as the protective snow cover diminishes, putting these glaciers at risk of completely melting in the future.
