Description: Marshy grassland and lowland wet heathland.
The pasture is made up of a mosaic of wet heath, mire, and marshy grassland dominated by Purple Moor Grass. Much of the grassland has plenty of Tormentil (6-9), together with species such as Sheep’s Fescue, Mat Grass and Heath Rush, and supports a strong, large population of Petty Whin (5-6). The wet heath is identified by the presence of Cross-leaved Heath (7-8) and Heather (8-9).
Occasional areas where the soil is slightly less acidic are distinguished by the presence of Meadow Thistle (6-7). Royal Fern has been found in two areas associated with the ditches on the site.
This open habitat supports breeding Meadow Pipit, and Skylark, and a variety of invertebrates including butterflies; hopefully the Marsh Fritillary (5-6) in future, and dragonflies such as the Common Darter (6-9).
