Extract

The Raso Lark Alauda razae is a globally endangered species that is endemic to the islet of Raso (16°93′ N, 24°38′ W) in the Cape Verde archipelago (Collar et al. 1994). Raso is a small (c.7 km2) uninhabited islet with a plain averaging 25 m in elevation to the south and west and small boulder-strewn hills to the north and east rising up to 164 m (Figure 1). The islet comprises mostly rocky desert, with some extensive sandy patches on the western plain. Vegetation is sparse and confined to small patches on the plains and along dry river valleys.
