Small mammals were surveyed along a deforestation gradient in southern Gansu, China (2300-2600 m altitude), a high endemicity area for human alveolar echinococcosis. Rodent distribution was assessed using removal trapping in six habitat types from timbered forest to farmland and villages, by index transects, and by the collection of specimens by local people, Species captured were 2 shrews: Anourosorex squamipes, Sorex sinalis-, 12 rodents: Eozapus setchuanus, Microtus limnophilus, Cricetulus long/- caudatus, Tscherskia triton, Apodemus agrarius, Apodemus draco, Apodemus penin- sulae, Micromys minutus, Mus muscitlus, Rattus noruegicus, Niviventer confucianus, Myospalax fontanieri\ and 1 lagomorph Ockotona thibetana. On the basis of trap success four rodent assemblages were recognized. Species richness decreases after deforestation, especially in the intermediate stage (scrubland-grassland).
