Optimal protection of the world’s threatened birds, mammals and amphibians

This chapter provides an update on how well threatened bird, mammal, and amphibian (BAM) species are represented in the global protected area estate. It compares protected area coverage for BAM species with the last available gap analysis conducted by Rodrigues et al. in 2004. The chapter identifies expansion priorities for the global protected area estate to achieve two different objectives. The first objective was to identify which additional areas of the planet need to be protected to represent each threatened species at least once, that is, to transition to a global protected area estate that has no gap species. The second objective was to determine how much land needs to be protected to achieve persistence targets for BAM threatened species. The chapter discusses the implications of the findings for the 2010 Aichi targets and the wider Convention on Biological Diversity (CBD) strategic plan more generally
