Fig. 10.14 Map of South Africa's Cape Floristic Region showing site irreplaceability values for achieving a range of conserva-
tion targets in the 20-year conservation plan for the region. Irreplaceability is a measure, varying from zero to one, which
indicates the relative importance of an area for the achievement of regional conservation targets. Existing reserves are
shown in blue. (After Cowling et al., 2003.) (This fi gure also reproduced as color plate 10.14.)
