NVC community W17 ( Quercus petraea - Betula pubescens - Dicranum majus 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 widely distributed community in northern and western Britain and represents mossy deciduous woodland of the uplands. There are four subcommunities.
Two constant species are found in the tree canopy of this community:
Eight constant species are found in the field and ground layers of this community:
Rare species associated with the community include Hymenophyllum wilsonii and a number of oceanic bryophytes.
This community is widespread throughout upland areas of Britain. The subcommunities show some geographical localisation with W17a predominantly western and W17d predominantly eastern.
There are four subcommunities:
UNESCO Biosphere Reserves are environment-protected scientific-research institutions of international status that are created with the intent for conservation in a natural state the most typical natural complexes of biosphere, conducting background ecological monitoring, studying of the surrounding natural environment, its changes under the activity of anthropogenic factors.

Minwear Wood is a Site of Special Scientific Interest in Pembrokeshire, South Wales. It has been designated as a Site of Special Scientific Interest since January 1968 in an attempt to protect its fragile biological elements including ancient woodland of sessile oak with hazel and downy birch on the upper part of the Milford Haven estuary. The wood is structurally diverse and has scarce plants and epiphytic lichens. The site has an area of 13.69 hectares and is managed by Natural Resources Wales.
Celtic Rainforest is a colloquial term which refers to the temperate rainforest of the British Isles. These woodlands are also variously referred to as Atlantic rainforest, Upland Oakwoods, Atlantic Oakwoods or Western Oakwoods. Today, the Celtic Rainforest exists as small fragments of the temperate rainforest that once covered much of Ireland and the west coast of Great Britain. The majority of these fragments occur on steep-sided slopes above rivers and lakes which have avoided clearance and intensive grazing pressure. There are notable examples in Scotland on the islands and shores of Loch Maree, Loch Sunart, Loch Lomond, and one of the best preserved sites on the remote Taynish Peninsula in Argyll. In Wales, they occur on steep-sided riverine gorges in Snowdonia and Mid Wales. In England, there are examples in the Lake District, and steep-sided riverine and estuarine valleys in South West England, including the Fowey valley in Cornwall, and the valley of the river Dart which flows off Dartmoor, and has rainfall in excess of 2 metres per year.
Mylia taylorii, or Taylor's flapwort, is a species of leafy liverwort.

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.
