GIRC was officially founded in December 1999, after the formal foundation proposal made in October 1998 in Varese, during the 2nd Congress of the Associazione Teriologica Italiana. The GIRC’s premises are at the Dipartimento di Biologia Strutturale e Funzionale dell’Università degli Studi dell’Insubria di Varese. The association aims to: A. promote the development of bat biology research in Italy, supporting and presenting studies at national and international levels to further a better understanding of bats and their ecosystems; B. coordinate and promote initiatives to protect nature, with special reference to bats; C. represent a reference point for public and private institutions in the fields of bat research and protec- tion; D. represent a reference point for international institutions for all issues concerning Italian bats; E. coordinate and promote actions to raise public awareness on bat biology and conservation issues.
