Maps to show spatial trends in annual mean grassland NPP values across the TRHR between 1988 and 2012. (A) The statistical significance of trends. Note that NPP data for 2000 and 2012 for the TRHR were obtained from Xu35; these data were generated using the global production efficiency model incorporated at a localized level. (B) Inter-annual variability in grassland NPP between 1988 and 2012. These maps were created using the software ArcMap 10.2.2 (http://www.esri.com/software/arcgis/arcgis-for-desktop)92.
