Mires in the British National Vegetation Classification system
This article gives an overview of the mire communities in the British National Vegetation Classification system.
Introduction
The mire communities of the NVC were described in Volume 2 of British Plant Communities, first published in 1991, along with the heath communities.
In total, 38 mire communities have been identified.
The mire communities consist of a number of separate subgroups.
- five bog plane communities (M17, M18, M19, M20 and M21)
- two wet heath communities (M15 and M16)
- four bog-pool communities (M1, M2, M3 and M4)
- four base-poor small sedge & rush communities (M5, M6, M7 and M8)
- six base-poor small sedge & Schoenus communities (M9, M10, M11, M12, M13 and M14)
- seven fen-meadow / rush-pasture communities (M22, M23, M24, M26, M25, M27 and M28)
- two soakaway communities (M29 and M30)
- eight communities of springs and rills (M31, M32, M33, M34, M35, M36, M37 and M38)
