Rodents account for 40 per cent of living mammal species. Nevertheless, despite an increased interest in biodiversity conservation and their high species richness, Rodentia are often neglected by conservationists. We attempt for the first time a world-wide evaluation of rodent conservation priorities at the genus level. Given the low popularity of the order, we considered it desirable to discuss identified priorities within the framework of established biodiversity priority areas of the world. Two families and 62 genera are recognized as threatened. Our analyses highlight the Philippines, New Guinea, Sulawesi, the Caribbean, China temperate forests and the Atlantic Forest of south-eastern Brazil as the most important (for their high number of genera) ‘threat-spots’ for rodent conservation. A few regions, mainly drylands, are singled out as important areas for rodent conservation but are not generally recognized in global biodiversity assessments. These are the remaining forests of Togo, extreme ‘western Sahel’, the Turanian and Mongolian-Manchurian steppes and the desert of the Horn of Africa. Resources for conservation must be allocated first to recognized threat spots and to those restricted-range genera which may depend on species-specific strategies for their survival.
