SPECIES-RICH WET GRASSLAND

Species-rich wet grassland: poorly-drained grassland with soft rush, sharp-flowered or jointed rush, often with a high cover of creeping bent-grass, common sedge or rough meadow-grass. Characteristic species are meadow buttercup, cuckoo flower, lesser spearwort, yellow flag, marsh marigold, creeping Jenny, marsh cinquefoil, watermint, sedges, ragged robin, marsh violet, marsh ragweed, meadowsweet, marsh horsetail and marsh stitchwort.

Species-rich wet grassland: summary of losses and gains 1991 - 1998.

Species-rich wet grassland: main losses and gains 1991 - 1998.
Loss of Species-rich wet grassland was mainly by conversion to grasslands with more agriculturally preferred species. Loss to poor fen is indicative of a reduced number of characteristic species and an increased cover of rushes. Habitats in the losses and gains table below are linked to their descriptors and NI data. Full details of all losses and gains are given in the technical report.
