At what level of plant growth, does it stop being "bare ground"? One "plant" (tree / shrub / patch of grass etc) per sq km / 100 / 10 / 1 sq m? Maybe, instead of saying it's bare ground, we need some way of describing the level of ground cover eg vegetation=sparse or similar? & while you say that it is a long-term thing, if you get decent rain, it can change virtually (& sometimes literally!) overnight: https://www.abc.net.au/news/2020-02-07/dams-start-to-fill-after-summer-rains-in-southern-queensland/11940556 Thanks Graeme
