Areas, which can be classified as wet heath, lie between the raised dry heaths and the bog and fen communities. Patches of rushes and low spreading brambles characteristically indicate these areas. Purple Moor Grass and Quaking-grass are also found as well as occasionally the uncommon Heath Spotted Orchid. Depending on the season the amount of water in the soil varies. This coupled with the unstable nature of the springs tends to create areas of wet heath where formerly they were grassland.
These marginal areas often have many flowers such as Marsh Thistle, Devil’s-bit Scabious, Ground Ivy and Water Mint, which attract many kinds of insects such as the Dark-edged Bee-fly, hoverflies, such as the Bog Hoverfly and solitary bees.
