BAP priority habitat typeWoodland site typeNVC equivalentDescriptionAssociated open ground habitats Other comments
Native pine woodlands Acidic dry (with Scots pine) W18 Native pinewood, either Scots pine dominant or pine with variable amounts of birch, rowan and/or juniper  Dry heaths, juniper scrub Also wet heaths & Molinia grassland in western pinewoods Stunted pine growing in bogs (bog woodland) is included in the Wet Woodland BAP priority habitat. Over time, mature Scots pine plantations may develop a plant community similar to that of native pine woodlands
Upland oakwood  Acidic dry (with no or very occasional Scots pine & frequent oak) W17 Oak woodland, with hazel, rowan and holly Gorse scrub, wet heaths, mires, bracken, Molinia grassland, acid grassland W17 communities occur on very acid soils. The field layer may contain heath species, large woodland mosses, bracken and/or grasses.  Woodland on mildly acidic brown earth soils with a grassy field layer (W11) is included in the ‘neutral dry’ woodland type
Upland oakwood Neutral dry W11 Oak woodland, with hazel and ash Bracken, grassland Atlantic hazelwoods may fit into this woodland type or into ‘dry basic’ woodland  
Upland birchwoods Acidic dry (birch dominant woodland with no or very occasional Scots pine or oak) W17, if birch dominated Birch woodland, with hazel, rowan and holly Gorse scrub. wet heaths, mires, bracken, Molinia grassland, acid grassland W17 communities occur on very acid soils. The field layer may contain grasses and/or bracken, less frequently heath species or large woodland mosses.  Woodland on mildly acidic brown earth soils with a grassy field layer (W11) is included in the ‘neutral dry’ woodland type
Upland birchwoods Neutral dry W11 Birch woodland with hazel Bracken, grassland Atlantic hazelwoods may fit into this woodland type or into ‘dry basic’ woodland 
Upland birchwoods Acidic wet W4a and b Birch woodland with willow Mires, wet heaths, Molinia grassland, rush pasture The wettest birch woodland in this woodland type, W4c, fits into the Wet Woodland BAP priority habitat Field layer communities vary but species typically include purple moor-grass, rushes and Sphagnum mosses. In the west, scrub willow may be the dominant tree type
Upland mixed ashwoods Base-rich dry W9 Species-rich woods of oak, ash and hazel Grassland  Herb-rich woodland, found on well-drained, base-rich soils but also as small areas associated with soils flushed with nutrients, e.g. ravines and rock outcrops. Atlantic hazelwoods may fit into this woodland type or into ‘Dry neutral’ woodland
Wet woodland Acidic wet W4c
W18
Birch woodland with willow. Native pine woodland Mires, wet heath, rush pasture Mostly birch woodland in very wet, acidic soils, though stunted Scots pine bog woodland is also included here. Willow scrub may be the dominant tree type in the west. Woodland cover is often patchy. Field layer communities vary but species typically include Sphagnum mosses
Wet woodland Neutral to base-rich wet W7,(W1,W2,W3) Wet alder or willow woodland Mires, fens, swamps, rush pasture A woodland of flushed soils, mostly herb-rich. Alder is often the main tree species in W7, though locally birch, willows, ash or hazel may dominate. W1, W2, W3 are very wet willow woodlands 
Lowland mixed deciduous woodland Acidic dry W16 Lowland or upland fringe oak or birch woodland on very acid soils Mires, heath, bracken

Occasionally the Lowland Mixed Deciduous Woodland BAP priority habitat is represented by this woodland community

The field layer is generally species-poor and heathy

Lowland mixed deciduous woodland Neutral dry W10 Lowland oak and/or birch woodland with hazel Grassland, arable fields,bracken, bramble scrub  A woodland of neutral to mildly acidic soils  Bramble, bracken and buckler ferns may be abundant; bramble may be rank if grazing is light 
Lowland mixed deciduous woodland Base-rich dry W8 Lowland ash and hazel woodland with hawthorn and elder Grassland, arable fields, bramble scrub Generally herb rich. Wild garlic or dog’s mercury may be abundant Light or no grazing may result in a rank bramble understorey
Wood pasture and parkland Any Any An open woodland, usually with mature or ancient trees n/a Wood pasture and parkland is a product of historic land management It can be represented in any woodland site type including upland site types
