This area of transition-mire, which is variably dominated by common cotton-grass (Eriophorum angustifolium), bottle sedge (Carex rostrata) and bogbean (Menyanthes trifoliata) hosts several locally scarce and rare species, such as slender cottongrass (Eriophorum gracile), bog sedge (Carex limosa) and white sedge (Carex canescens). However, the combined effects of increasing wetness, nutrient enrichment and undermanagement have resulted in swamp species (notably Phragmites australis) and scrub encroaching into the transition mire.
