الوصف: Small mammal species diversity in the major vegetation zones of Bwindi Impenetrable National Park is discussed in relation to altitude. Species richness of the small mammals was found to decrease with an increase in altitude. The main factors accounting for the observed diversity are the wide altitudinal variation and a complex array of vegetation types. Sixty-seven species of rodents and shrews were found to exist in the Park; 47 of which were rodents and 20 shrews. Of these, 26 species are new to the Bwindi Park list. Three species have probably not been described before. The study found 10 species of small mammals to be Albertine Rift endemics. Three genera are recorded in Uganda for the first time: Rwenzorisorex, Suncus and Paracrocidura. Five species are new records for East Africa. These are Crocidura stenocephala, Lophuromys rahmi, L. medicaudatus, Paracrocidura maxima and Hylomyscus aeta. Because of the high endemism of plants, butterflies, birds and now of small mammal species, Bwindi forest is a unique biodiversity hotspot and is among the highest conservation priorities in the Albertine Rift. Resume On discute de la diversite des especes de petits mammiferes dans les principales zones de vegetation du Parc de la Foret Impenetrable de Bwindi, en fonction avec l'altitude. On a trouve que la richesse en especes de petits mammiferes diminuait avec l'augmentation de l'altitude. Les principaux facteurs qui expliquent la diversite observee sont la grande variation de l'altitude et un ensemble complexe de types de vegetation. On a decouvert que soixante-sept especes de rongeurs et de musaraignes vivent dans le parc, dont 47 rongeurs et 20 musaraignes. Parmi eux, 26 especes sont nouvelles sur la liste du Parc de Bwindi. Trois d'entre elles n'ont probablement jamais ete decrites auparavant. L'etude a decouvert que 10 especes de petits mammiferes sont endemiques au Rift Albertin. Trois genres sont rapportes pour la premiere fois pour l'Ouganda : Rwenzorisorex, Suncus et Paracrocidura. Cinq especes sont nouvelles pour l'Afrique de l'Est : Crocidura stenocephala, Lophuromys rahmi, L.medicaudatus, Paracrocidura maxima et Hylomyscus aeta. Etant donne le fort endemisme de plantes, de papillons, d'oiseaux et maintenant, de petits mammiferes, la foret de Bwindi est un haut lieu unique de la biodiversite qui se range parmi les plus urgentes priorites de la conservation du Rift Albertin.
