Remarks on the distribution and use of a provisional red list of the ants of Flanders (Formicidae, Hymenoptera)

In the beginning of 2001 all available data of ants in Flanders (northern part of Belgium) were brought together and several inventory works were started. Some general conclusions on the distribution and diversity of the ants of Flanders and their habitat width are discussed and a provisional Red List is presented and its possible use is evaluated. Further we assess for which habitat-types ants could be indicators. In Flanders heathlands have the most stenotopic and threatened ant fauna. We provide a list of species which should be monitored in those sites and can be used to evaluate sites together with red list of other invertebrate groups.
