Illustration of change in woody cover that resulted from intersect GIS overlay analysis. a, b The study sites with long-term gains, and c, d the sites with long-term losses in woody cover. All sites had a core of stable woody cover (in green), as well as gained or lost woody cover (in brown). The overlay analysis used locations common to all dates on the respective extracted woody cover thematic layers of the study sites in Fig. 3. The woody cover is mapped here at the 10 m pixel size, which was the pixel size of the lowest resolution SPOT images. a Ngwenyeni site, b Mooiplaas site, c Stevenson-Hamilton site, d Nhlowa site
