Fig. 3: Spatial pattern of stocking rate thresholds on the Qinghai-Tibetan Plateau (QTP) and difference between thresholds and actual stocking rate.
From: An early warning signal for grassland degradation on the Qinghai-Tibetan Plateau
Maps were masked with the initial grassland distribution shown in Fig. 1. a Stocking rate thresholds. b Distribution of threshold values in terms of amount of surface area. Discrepancy between stocking rate thresholds and actual stocking rate, expressed as (c) absolute differences or (d) ratios, where the bar chart indicated the area percentage of overgrazing (red) and normal grazing (blue) in c and the area percentage of different ratio range in d (blue and red represented ratio <1 and ≥1 separately). SR stocking rate, SU sheep unit, OG overgrazing, NG normal grazing.
