Restoring opportunities for ecoregions
Nature Needs Half is one of the approaches proposed to identifying actions supporting the post-2020 global biodiversity framework, focusing on protecting, conserving, restoring and retaining natural areas of land and sea. Nature Needs Half call for protection of half of any region.
Applying the NNH concept to ecoregions, Dinerstein et al. (2017) defined 4 ecoregions classes. Ecoregions in the class Nature Could Recover would require restoration to reach Half Protected because the amount of available habitat outside protected areas plus the existing protected areas is below 50% but more than 20%.
