Collaboration for Environmental Evidence: www.en vironmentalevidence.org/ SR10007 .html. 1 Summary Background Protected areas cover up to 15.5% of the planet’s land surface and are amongst the most important tool to maintain habitat integrity and species diversity. Unfortunately, despite the increase in coverage, there is considerable debate over the extent to which protected areas deliver conservation outcomes in terms of species populations, habitat coverage, or habitat condition.
