The small mammal fauna inhabiting the Svitavská pahorkatina Upland (Eastern Bohemia) was studied over the 2006–2010 period. The region, 1700 km2 in approximate area, is largely agricultural (woodland not exceeding 30%), with a relatively poor network of streams. The region corresponds to 19 quadrats of the standard mapping grid. Despite its rather small size, the region harbours fairly diverse small mammal fauna, comprising three quarters of the total number of species known from the whole territory of the Czech Republic. The study revealed the presence of 46 small mammal species (9 insectivores, 17 bats, 20 rodents). For each of the species, a complete list of known localities and a brief description of their occurrence is presented. Of greatest zoogeographic significance are the findings of Crocidura leucodon and Apodemus agrarius, recorded outside their hitherto known ranges. Lack of wetland habitats is the cause of the markedly fragmented occurrence of Microtus agrestis, while Neomys anomalus show no such tendence. The results have confirmed the expected importance of the Svitavská pahorkatina Upland as a link between different biogeographic regions lying in the Bohemian and Moravian borderland. The paucity of woodland permits rather thermophilous species to spread from the east in the westerly (e.g. Rhinolophus hipposideros, Myotis blythii, M. emarginatus) or the north-south direction, and it contributes to maintaining continuity of rather psychrophilous species inhabiting the Bohemian-Moravian Highlands and the Sudetes Mts. (e.g. Eptesicus nilssonii). On the other hand, no evidence has been obtained of the continuous occurrence of Sorex alpinus in the foothills of the Orlické hory Mts. and the Bohemian-Moravian Highlands (most probably because it is probably nonexistent due to the present environmental condition of the region).
