By means of systematic transects and directed tramping, a checklist of the tarrestrial mammals found at Carmen Island was obtained. 6 species were found, of which 4 are native to the island, and 2 were introduced.

This study generated the information needed for the mammals chapter of the book: Carmen Island’s Field Guide of Flora and Fauna.
