Figure 2. Cumulative number of Single Site Threatened Species (SSTS) prioritised on the basis of number of species (n); purchasing power parity (PPP); corruption index (CI), CI*PPP, CI*PPP*n against the proportion of the total funds required to maintain all SSTS ((n*CI*PPP)/Σ(n*CI*PPP)).
PPP and CI*PPP are virtually overlapping so only symbols are presented for CI*PPP.
