To answer the question of how much land is needed to
protect biodiversity, we focused on globally critical sites
for species and habitats.
These areas have been identified at a national
level by local stakeholders using a set of transparent and
globally standardized criteria to ensure scientific soundness and will thus be
informative for a global estimate. Recent research shows
that more than half of all these important sites for
biodiversity remain unprotected and many are within Biodiversity Hotspots
