Wet Grassland and Fen Habitats

Wet grassland habitats are generally low-lying areas and often floodplain grasslands with damp or waterlogged soils for much of the year. In spring, they will often have wet flushes and high ditch water tables and are of great importance for breeding waders such as Lapwing and Redshank. They also support a wide variety of other bird species, as well as grasses, wildflowers and insects. These habitats are important for biodiversity, flood control and grazing livestock.

Fens are peat-forming wetlands fed by groundwater that is rich in minerals. The habitat is comprised of reeds, sedges, mosses and rare plants adapted to constantly wet conditions. They provide valuable habitats for birds such as Snipe and Curlew, as well as for amphibians and insects. Fen habitats also help to store carbon and filter water.

Areas of Opportunity for Restoration

Floodplain callows, including those on the Shannon and the Little Brosna rivers in the Midlands, have come out as top sites for restoration of both breeding and wintering birds associated with the wet grassland and fen habitat group. We identified 57 km2 of wet grassland and fen habitat in Natura 2000 sites (40 km2 in SACs and 17 km2 in SPAs) that should be restored to benefit bird species.

Restoration Measures

Restoration measures include restoring natural hydrology, maintaining shallow winter floods and summer high water tables, creating a mosaic of short and medium sward through carefully timed grazing and mowing, provision of safe roosting and feeding areas and reducing disturbance and predation by corvids and mammals.
