Since the publication of “The Atlas of European Mammals” in 1999 plenty of new data have been collected on the distribution of Apodemus spp. in Lithuania. These data have changed our knowledge of the comparative distribution of ?A. sylvaticus and A. uralensis in the country. Essentially, A. uralensis is widespread in the north-western part of the country, whereas A. sylvaticus is found only in southern and eastern Lithuania. Both species reach the limits of their geographical ranges in Lithuania.
