Conservation: ‘Silver bullet’ Strategies Due A Rethink
London (UK), 09 November: Conservation strategies that generalize from the distribution of one threatened species to that of another may be flawed, a study in this week’s Nature suggests.
Ian Owens and colleagues studied a database of over 19,000 living bird, mammal and amphibian species to see whether biodiversity patterns were similar. Although the three groups were similar in terms of overall species richness, the distribution of threatened and rare species was different for each group. This means that the distribution of rare birds, for example, does not predict the distribution of rare species in the other two groups.
By themselves, so-called ‘silver bullet’ conservation strategies are unlikely to deliver efficient conservation, the authors say. Instead, priority areas for biodiversity conservation should be based upon high-resolution data from multiple species.
