Other Site Characteristics

Rahasane is a very large turlough consisting of grassland and marshes sunk in an area of outcropping limestone. It is fed by a large catchment (Dunkellin River) and so is naturally eutrophic and productive with a large number of wintering birds. There is a little marl but no peat in the basin. The river flows through most of the area and its natural course is the centre of a significant aquatic community.

4.2 Quality and importance

This site has an excellent variety of vegetation, several rare plant species and huge bird populations in winter. It supports internationally important numbers of Cygnus cygnus, Anas penelope, Anas clypeata and Pluvialis apricaria. It is the largest site inland for Calidris alpina in Ireland and Britain. It was also the first place that Tanymastix stagnalis was found in these islands.
