British NVC community OV38

Last updated

British NVC community OV38 (Gymnocarpium robertianum - Arrhenatherum elatius community) is one of the open habitat communities in the British National Vegetation Classification system. It is one of six communities of crevice, scree and spoil vegetation.

Contents

This is a localised community, which is restricted to areas of calcareous bedrock, mostly Carboniferous limestone, in England and Wales.

There are no subcommunities.

Community composition

The following constant species are found in this community:

There are no rare species associated with the community.

Distribution

This is a local community, found mainly on Carboniferous limestone in England and Wales. It is an early coloniser of limestone screes and slopes, but is only able to persist if the talus if especially coarse or if there is limited grazing, both conditions which inhibit invasion by scrub and woodland species.

This community was first described in Britain by Shimwell, who assigned it to the Gymnocarpietum robertianae (Kuhn 1937), previously described from Germany.

Coombs Dale Valley in the Derbyshire Peak District

Coombs Dale is a steep-sided, dry carboniferous limestone valley in the Derbyshire Peak District of England. The village of Calver lies about 1 km to the east and the village of Stoney Middleton lies less than 1 km to the north. The dale is cut into the hills on the east side of Longstone Moor. The upper end of the dale is known as Rough Side. Several springs flow down the dale during winter and after heavy rains.
