Annex I habitats that are a primary reason for selection of this site
|3260 Water courses of plain to montane levels with the Ranunculion fluitantis and Callitricho-Batrachion vegetation|
|The Upper Ballinderry River rises in the Sperrin Mountains in Northern Ireland and flows eastwards into Lough Neagh. It is a moderately large river and ranges in type from oligo-mesotrophic to mesotrophic. The river is notable for the physical diversity and naturalness of the bank and channel, and the richness and naturalness of its plant and animal communities. In the middle reaches, common aquatic bryophytes are Chiloscyphus polyanthos, Amblystegium fluviatile, Fontinalis antipyretica and Rhynchostegium riparioides. In addition, beds of stream water-crowfoot Ranunculus penicillatus ssp. penicillatus are abundant in the river channel, often growing in association with intermediate water-starwort Callitriche hamulata and large-leaved pondweeds Potamogeton spp.|
