A diagram of changes in vegetation homogenization along elevational gradients. The vegetation activity here is showcased with the example of the maximum three-monthly normalized difference vegetation index (NDVImax3). Along the elevation, the multi-year averaged elevational gradient (EG) sign can be either (1) increasing vegetation activity (positive EGndvimax) or (2) decreasing vegetation activity (negative EGndvimax). Over time, the EG sign can either (A) amplified or (B) reduced. The combined changes along the elevation and over time for EG dynamics are illuminated in Fig. 3. Here (1A, a) and (2A, c) indicate decreased elevational vegetation homogenization; while (1B, b) and (2B, d) imply increased vegetation homogenization
