Location: Week St. Mary, Cornwall OS: SX 234963 What Three Word location:///wobbles.cats.digs
Habitat: Culm grassland
Greena Moor is an excellent example of culm grassland where ‘culm’ refers to the rocks underneath the clay soil.
Always sparse, culm grassland suffered a catastrophic decline through agricultural ‘improvements’. The reserve is a fragment of what was once an extensive moorland and mire system, including large areas of culm grassland. It is fringed by wet woodland of alder and willows.
The nationally scarce Wavy St-John’s-wort Hypericum undulatum and Three-lobed Water Crowfoot Ranunculus tripartitus can be found here. Devil’s-bit Scabious Succisa pratensis is an important food plant for the Marsh Fritillary butterfly which are active on the reserve.
Purchase of the reserve was made possible by Unilever. Managed in partnership with Cornwall Wildlife Trust.
Culm measures are a kind of rock from the Carboniferous era that contains thin bands of impure anthracite or culm, found only in Cornwall, Devon, the New Forest and South Wales
