Extended Data Table 2 Difference in the estimated reduction of global species persistence (δp) associated with the loss of a protected or non-protected wilderness pixel

From: Wilderness areas halve the extinction risk of terrestrial biodiversity

  1. The first row reports the mean δp values observed across all protected wilderness grid cells of a biogeographical realm. The second row reports the average across 1,000 mean δp values obtained by randomly selecting an equivalent number of wilderness cells. The third row reports the percentage of times in which the observed mean δp value was higher than the mean δp value from a random sample (out of 1,000 random samples). The fourth row reports the effect size (Cohen’s d statistic) of the difference between δp values in protected and non-protected wilderness cells. AA, Australasia; AT, Afrotropical; IM, Indomalayan; NA, Nearctic; NT, Neotropical; PA, Palaearctic. The Oceanian and Antarctic realms were excluded from analyses.
