The woodland and scrub communities of the NVC were described in Volume 1 of '' British Plant Communities '', first published in 1991.
In total, 25 woodland/scrub communities have been identified, consisting of 20 woodland communities, three communities classed as scrub and two as underscrub.
The woodland communities consist of:
- Six mixed deciduous or Oak / Birch woodland communities, which between them are found throughout Britain (communities W8 , W9 , W10 , W11 , W16 and W17 )
- Three Beech woodland communities, found mainly in southern England ( W12 , W14 and W15 )
- A Yew woodland community, almost completely restricted to southeast England ( W13 )
- A Scots Pine woodland community, restricted to Scotland ( W18 )
- A Juniper woodland community ( W19 )
- Seven wet woodland communities, characterised by the presence of Alder , Birch and Willow s (communities W1 , W2 , W3 , W4 , W5 , W6 and W7 ).
- An arctic-alpine Willow community ( W20 )
The three scrub communities (where such as Hawthorn , Blackthorn and Elder , Gorse and Broom predominate) are W21 , W22 and W23 .
The two underscrub communities, where Bramble is a constant species are W24 and W25 .
A further scrub community, SD18 , dominated by Sea Buckthorn , is classified among the Sand-dune Communities .
