'Silver-bullet' approaches to conservation assume that conservation strategy can be based on the distribution of species in one or two well known taxonomic groups, as there is high cross-taxon congruence in large-scale patterns of biodiversity. Although birds, mammals and amphibians show similar patterns in terms of overall species richness, the distribution of threatened and rare species is found to be different in each group.
