In the field, totally 300 mires were identified and mapped, of which 58 were selected for the detailed analysis of this study. Physical, chemical, floristic, hydrological and geomorphologic data of the mires were collected in 1997–2004. The data were organized and analysed using ordination methods (CA). A detailed distribution map of the mires in the Island is presented. Three major mire site groups occurring in Azores were identified: (1) Basin mires; (2) Transition and raised mires and (3) Hillside and blanket mires. The profiles and the plant species of these site type groups are presented.
