Acid grassland
Acid grassland is a nutrient-poor habitat characterised by grassy tussocks and bare ground.
==Habitat==
The vegetation is dominated by grasses and herbaceous plants, growing on soils deficient in lime (calcium). These may be found on acid sedimentary rock such as sandstone; acid igneous rock such as granite; and fluvial or glacial deposits such as sand and gravel. Typical plants of lowland acid grassland in Britain include common bent grass, ''Agrostis capillaris'', wavy hair-grass, ''Deschampsia flexuosa'', bristle bent grass, ''Agrostis curtisii'', tormentil, ''Potentilla erecta'', and flowers such as sheep's sorrel, ''Rumex acetosella'' and heath bedstraw, ''Galium saxatile''.〔(【引用サイトリンク】url=http://jncc.defra.gov.uk/page-3559 )〕
