On the occurence of bats (Chiroptera) in South Tyrol : 2. Vespertilionidae

  • On the occurence of bats (Chiroptera) in South Tyrol (2): Vespertilionidae Since 1988 the author has been collecting and recording bat observations in South Tyrol. From 1990 to 1991 and from 1995 to 1997, in two different studies, he carried on a survey on the presence, the frequency and the horizontal and vertical dispersal of the various species of bats. The first task was on one hand to search the attics and steeples of about 700 churches and chapels; and, on the other hand, to answer the numerous calls telling of the presence of bats in private houses, to capture bats for a check-up and to inform people about European bats beeing harmless for humans, animals and houses. There is good evidence of 23 species of bats in South Tyrol since 1988 and of the reproduction of 18 of them, as well as there are single discoveries of three further species, and finally summer colonies of two species. As there is no certified evidence of the presence of Pipistrellus pygmaeus and of Plecotus alpinus they have not been included in this record. The data-base already provides a good idea of the presence and frequency of bat-species. Species which are frequent in Central Europe have been found almost everywhere in South Tyrol (e.g. Pipistrellus pipistrellus, Plecotus sp.), some of them in several colonies with a considerable number of individuals. The Etsch/ Adige Valley as far up as Meran/Merano - due to its mild climate - makes home for a few Mediterrean species. The few possibilities we got from scientific pubblications to make a comparison with former times let suppose that the bat occurences have diminued only in a few species. The reasons are to search mainly in the diminued offer of food.
