Production diversification of rubber-based (RB), pig-based (PB), and livestock-corn-based (LB) farming systems in the Naban River National Nature Reserve, Xishuangbanna. Each dot in the spider web displays the relative importance of one production branch whereby 1 is equivalent to the highest relative possible expression of a trait found in the total population (for example, PB farms, compared with RB and LB farms, have the highest average tea-field size (0.890 ha); their relative-tea-score was set to 1. In comparison, average tea-field size on LB farms is 0.531 ha, which is 60 % of PB tea field size; consequently, their tea-score is 0.6), and a broad web indicates a higher level of diversification
