1988
Baeumler, W. (Muenchen Univ. (Germany, F.R.). Lehrstuhl fuer Angewandte Zoologie)
About 150,000 nest boxes were examined in the years 1985 and 1986 in 160 forest districts. Additionally the record books about nestbox contents were checked in 35 districts (200,000 hectares) for the last 2-3 decades. The distribution of bats and dormice was mapped out according to the available data. The absolute number and the percentage of nestboxes occupied by bats increased in the two decades passed. The dormice, especially the Edible Dormouse (Glis glis) increased too, mainly in the western parts of Bavaria. Some hints are given for more detailed investigations about key factors of distribution and development of bats and dormice
