NVC community W11 ( Quercus petraea - Betula pubescens - Oxalis acetosella woodland) is one of the woodland communities in the British National Vegetation Classification system. It is one of the six communities falling in the "mixed deciduous and oak/birch woodlands" group.
This is a widespread upland community of northern and western Britain. There are four subcommunities.
The following constant species are found in this community:
No rare species are also associated with the community.
This community is widespread throughout upland areas in northern and western Britain, where is replaces community W10. It is particularly well represented in Scotland, north Wales, and northwest England. It is also present in the Southwest Peninsula.
There are four subcommunities:
Betula pendula, commonly known as silver birch, warty birch, European white birch, or East Asian white birch, is a species of tree in the family Betulaceae, native to Europe and parts of Asia, though in southern Europe, it is only found at higher altitudes. Its range extends into Siberia, China, and southwest Asia in the mountains of northern Turkey, the Caucasus, and northern Iran. It has been introduced into North America, where it is known as the European white birch or weeping birch and is considered invasive in some states in the United States and parts of Canada. The tree can also be found in more temperate regions of Australia.
Betula pubescens, commonly known as downy birch and also as moor birch, white birch, European white birch or hairy birch, is a species of deciduous tree, native and abundant throughout northern Europe and northern Asia, growing farther north than any other broadleaf tree. It is closely related to, and often confused with, the silver birch, but grows in wetter places with heavier soils and poorer drainage; smaller trees can also be confused with the dwarf birch.
Oxalis is a large genus of flowering plants in the wood-sorrel family Oxalidaceae, comprising over 550 species. The genus occurs throughout most of the world, except for the polar areas; species diversity is particularly rich in tropical Brazil, Mexico, and South Africa.

NVC community W2 is one of the woodland communities in the British National Vegetation Classification system. It is one of seven woodland communities in the NVC classed as "wet woodlands".
British NVC community MG2 is one of the mesotrophic grassland communities in the British National Vegetation Classification system.
NVC community CG10 is one of the calcicolous grassland communities in the British National Vegetation Classification system. Of the upland group of calcicolous grasslands, it is the only one with a short sward associated with heavy grazing.
NVC community W8 is one of the woodland communities in the British National Vegetation Classification system. It is one of the six communities falling in the "mixed deciduous and oak/birch woodlands" group.
NVC community W9 is one of the woodland communities in the British National Vegetation Classification system. It is one of the six communities falling in the "mixed deciduous and oak/birch woodlands" group.
NVC community W10 is one of the woodland communities in the British National Vegetation Classification system. It is one of the six communities falling in the "mixed deciduous and oak/birch woodlands" group.
British NVC community MG3 is one of the mesotrophic grassland communities in the British National Vegetation Classification system. It is one of four such communities associated with well-drained permanent pastures and meadows.
Deschampsia flexuosa, commonly known as wavy hair-grass, is a species of bunchgrass in the grass family widely distributed in Eurasia, Africa, South America, and North America.
NVC community CG6 is one of the calcicolous grassland communities in the British National Vegetation Classification system. It is one of four communities of rank, tussocky grassland associated with low levels of grazing, within the lowland calcicolous grassland group.
Grass Wood is an ancient woodland of 88 hectares in Wharfedale, North Yorkshire, England, that has an exceptional ground flora of woodland wildflowers.
NVC community W17 is one of the woodland communities in the British National Vegetation Classification system. It is one of the six communities falling in the "mixed deciduous and oak/birch woodlands" group.
NVC community U19 is one of the calcifugous grassland communities in the British National Vegetation Classification system.
Bewick and Beanley Moors is the name given to a Site of Special Scientific Interest (SSSI) in north Northumberland, in the north-east of England. The moors are asserted to be of national importance by Natural England for the extent, quality and diversity of upland types including heaths, fens, wet grassland, flushes, mires and blanket bogs, together creating an extensive mosaic habitat supporting an exceptional community of amphibians. The moors are important, too, for their relict juniper woodland and scrub.
Billsmoor Park and Grasslees Wood is the name given to a Site of Special Scientific Interest (SSSI) in Northumberland, North East England, designated in 1954. Billsmoor Park is an extensive alder woodland of a sort increasingly uncommon in the county; the much smaller Grasslees Wood is an oak woodland.
Briarwood Banks is the name given to a woodland Site of Special Scientific Interest (SSSI) in north Northumberland, North East England. Composed mainly of elm, oak and ash, the site is semi-natural and now recovering from the removal of planted conifers.
Pillar and Ennerdale Fells is a Site of Special Scientific Interest (SSSI) in Ennerdale, Cumbria, England. Protected for its biological interest, the site is named after Pillar, which at 892 metres (2,927 ft) is the eighth-highest mountain in the Lake District, and other fells in the same range. The area is 425.25 ha.
