It has been reported that fog showed positive impacts on vegetation from various ecosystems in many parts of the world such as the Namib Desert (Eckardt et al., 2013;Mitchell et al., 2020), the coastal California redwood forest (Burgess & Dawson, 2004), and the Atacama Desert (Aravena et al., 1989). Fog can maintain vegetation photosynthetic function and sustain biogeochemical dynamics during rainless periods (Scholl et al., 2011;Wang et al., 2017). Previous studies have demonstrated the mechanisms of plant fog water uptake in drylands either through foliar water uptake or through shallow roots (
