Key Regions

Our Key Regions are those regions of world that are home to globally important aggregations of threatened small mammals.  We have conducted an analysis of species distribution data published by the Global Mammal Assessment (2008) to pinpoint regions that support high density and distinct aggregations of globally threatened species, such as the dry forests of south Mexico, Cameroon Highlands in west Africa and northern Borneo in Indonesia.  These regions are also typically characterized as supporting high numbers of Data Deficient species – in other words species for which we have very little ecological data to assess extinction risk. We have also identified regions which support ‘above average’ levels of extinction risk, such as the Caribbean where 13 of 15 small mammal species are considered globally threatened.

We are currently recruiting SMSG Key Region Coordinators to build networks of conservation scientists and professionals within these priority regions to enable more effective data gathering for Red List assessments, field conservation research and strategic planning.  Explore the map below to find out more about these globally important regions for small mammal conservation and some of the species that are found there.
