This site follows the Little Brosna river from its junction with the River Shannon callows (site 131) for 9 km south-eastwards to just beyond New Bridge. It is situated 6 km north-west of Birr, in Counties Offaly and Tipperary. The main habitat is callow (low-lying, semi-natural, wet grassland), which is seasonally flooded between October and April.
This is an internationally important wetland, regularly supporting over 20,000 wintering waterfowl. Additional species wintering in numbers of national importance include Anas platyrhynchos (700 birds, 1996), Anas acuta (250 birds, 1996), Anas clypeata (200 birds, 1996), Pluvialis apricaria (8,100 birds, 1996), Vanellus vanellus (6,500 birds, 1995) and Calidris alpina (1,250 birds, 1995). Until recently Crex crex were breeding (2 pairs, 1993).
