Eriophorum vaginatum
Much of the high bog possesses vegetation typical of an Irish Midland raised bog, with such species as ling heather ("Calluna vulgaris") and hare's tail cottongrass ("Eriophorum vaginatum"). The hummock-forming bog moss, "Sphagnum papillosum" has been recorded situated around one third of the high bog as has the more scarce "Sphagnum imbricatum". Overall, sphagnum covers around one-third of the high bog area. The centre of the bog is wet with stagnant water in places. The aquatic bog moss "Sphagnum cuspidatum" has been recorded in the hollows of the bog. There are dried-out channels of the bog which are colonised by algae, deergrass ("Trichophorum cespitosum") and lichens. On the cutover on the southeast shore of the lake there are areas of downy birchy ("Betula pubescens") woodland, with patches of gorse ("Ulex europaeus").
