Eriophorum angustifolium
Ecology
A rhizomatous perennial of open, wet, peaty ground, both calcareous and acidic, sometimes colonising peat-cuttings and often growing in standing water. Its habitats range from upland blanket bogs and hillside flushes to wet heaths and marshy meadows in the lowlands. 0-1100 m (Ben Alder, Westerness).
Status
Trends
Drainage, groundwater extraction and the cessation of grazing at some sites have considerably reduced the abundance of this species in the lowlands. Analysis of the database reveals that many losses took place before 1950, but have continued since then. In Hertfordshire, most sites were lost by 1900, and all by 1979 (James & Goldsmith, 1993).
