Animals in Sierra Leone

19 mammal species are recorded in Sierra Leone in this dataset, 7 of them in a threatened Red List category. Sierra Leone sits in Africa, where 267 species are recorded in total. Every species below is listed because the range description of its IUCN Red List assessment names Sierra Leone.

They belong to 8 families, the best represented being Bovidae (6), Anomaluridae (3), Cercopithecidae (3). By Red List category: 6 Endangered, 1 Vulnerable, 5 Near Threatened, 7 Least Concern.

These counts come from the text of each assessment rather than from an official country checklist, so a species whose assessment names a region without naming Sierra Leone is missing here, and a wide-ranging animal is counted in every country it crosses. All 19 of them have a full written profile.
