001819 Lough Bawn pNHA

SITE SYNOPSIS 

SITE NAME: LOUGH BAWN pNHA

SITE CODE: 001819 

 

Lough Bawn is a relatively small site composed of raised bog, fen, wet and dry woodland and freshwater marsh habitats. It is the area of fen however that gives this site its primary scientific interest. The area of fen/freshwater marsh is now to be found in a region originally occupied by the open waters of Lough Bawn. The water table has dropped considerably however and now one finds sedge - dominated vegetation covering the greater proportion of the former lake.

The fen habitat itself is still quite wet and it is not unusual to find standing water up to a depth of fifty centimetres. Sedges such as lesser tussock sedge (Carex diandra), Bottle Sedge (Carex rostrata) and greater tussock sedge (Carex paniculata) are well represented throughout this community. Areas of open water are still to be found here and one encounters species such as Bulrush (Typha latifolia), Horsetail (Equisetum fluviatile) and Bottle Sedge (Carex rostrata).

The intact raised bog on the site is interesting in that, although quite dry, Heather (Calluna vulgaris) isn't very well developed here. The bog surface may be burnt occassionally and it is noteworthy that all the adjacent and surrounding bog has either been drained, cut over or planted with conifers.

The habitat diversity of the site is augmented by presence of small areas of both wet and dry woodland. Alder (Alnus glutinosa), Birch (Betula pubescens) and Willows (Salix spp.) are all to be found here. Little information is avilable on the birdlife at this site but snipe, curlew, lapwing and pheasant were all observed during this visit. Any further drainage and/or peat extraction should be discouraged if we are to maintain the wetland habitat at Lough Bawn.
