WILDLIFE conservationists use the crite - rion of species diversity to identify areas that must be protected.

This matters as limited funds are available for conservation projects.

The model identified 41 ecoregions which are the most suited for conservation. The species in these regions live under a high risk of extinction. At the same time these lands can be acquired at a cheap cost. These regions are concentrated in Africa, South America and South Asia. The analysis was reported in the August issue of PLoS One.
