The research focused on identifying fens in Counties Down and Armagh where the incidence of inter-drumlin fens is high. These fens are particularly important within Annex 1 of the Habitats Directive. The most extensive and diverse priority Lowland Fens and Reedbeds have also been identified in county Tyrone through surveys by HST. This only represents a partial dataset and does not include the complete priority Lowland Fen and Reedbed resource in Northern Ireland. Where point data only is available for older fen surveys across Northern Ireland, further mapping is required to provide a fuller representation of all priority fen communities in Counties Fermanagh, Derry/Londonderry and Antrim.

Upland Flushes, Fens and Swamps are largely unrecorded.
