AbstractGovernments have committed to conserving _17% of terrestrial and _10% of marine environments globally, especially ñareas of particular importance for biodiversityî through ñecologically representativeî Protected Area (PA) sys- tems or other ñarea-based conservation measuresî, while individual countries have committed to conserve 3_50% of their land area. We estimate that PAs currently cover 14.6% of terrestrial and 2.8% of marine extent, but 59_68% of ecoregions, 77_78% of important sites for biodiversity, and 57% of 25,380 species have inadequate coverage. The existing 19.7 million km 2 terrestrial PA network needs only 3.3 million km 2 to be added to achieve 17% terres- trial coverage. However, it would require nearly doubling to achieve, cost- ef_ciently, coverage targets for all countries, ecoregions, important sites, and species. Poorer countries have the largest relative shortfalls. Such extensive and rapid expansion of formal PAs is unlikely to be achievable. Greater fo- cus is therefore needed on alternative approaches, including community- and privately managed sites and other effective area-based conservation measures.
