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.
