Rarities on Carrowbehy / Caher Bog
Other important habitats which occur within the site include dry heath and alkaline fen. Along the south-eastern edge of the northern lobe there is an area of semi-natural lagg which supports alkaline fen and poor fen vegetation. Lagg areas such as this are of great interest in terms of hydrology and vegetation and are now very rare features of raised bog systems in Ireland.
The relatively rare Brown Beak-sedge (Rhynchospora fusca) has been recorded from wet pools within the site and Red Grouse (Lagopus lagopus), a Red Data Book species, has also been noted.
