NVC community SD17 (Potentilla anserina - Carex nigra dune-slack community) is one of the 16 sand-dune communities in the British National Vegetation Classification system.
It is one of five communities associated with dune slacks.
It is a very localised community. There are four subcommunities.

No rare species are associated with the community.
This community is found in two areas - on the east coast, from Spurn Point to northwest Norfolk, and on the dunes of Liverpool Bay.And north Wales.
There are three subcommunities:
NVC community CG7 is one of the calcicolous grassland communities in the British National Vegetation Classification system. It is one of three short-sward communities associated with heavy grazing, within the lowland calcicolous grassland group, and is regarded as the eastern counterpart of "typical" chalk grassland.
