Stipa purpurea (light green), Heteropappus altaicus (lavender), Cardamine tangutorum (orange), Thermopsis (yellow), Potentilla bifurca (lime), and Oxytropis spp. (blue). Shown are mean differences between within and outside livestock exclosure fences, with all values calibrated to zero difference in 2009, the year exclosures were established. Individual experiments are indicated by slender solid (2), compound dash (3 and 4), short dash (4 only), long dash (7 and 8), compound short dash (9), dash-dot (10), and thick solid (12) lines.
