Previous assemblage name: F131 & F132

Linked assemblage: F111 bare sand & chalk & F112 open short sward; it is possibly a sub-community of either SAT, and has a small group of marker species.

Description of habitat typically supporting the assemblage: 

Current ISIS code: F221

Previous assemblage name: n/a

Linked assemblage: n/a

Previous assemblage name: W111 water bodies in acid mire matrix.

Linked assemblage: W312 Sphagnum bog, or F221 montane & upland.

Description of habitat typically supporting the assemblage: This aquatic, predominantly upland SAT was reviewed in 2008. It is probably be sensitive to nutrient enrichment and temperature rise.
