Mercurialis perennis, commonly known as dog's mercury, is a poisonous woodland plant found in much of Europe as well as in Algeria, Iran, Turkey, and the Caucasus, but almost absent from Ireland, Orkney and Shetland. A member of the spurge family (Euphorbiaceae), it is a herbaceous, downy perennial with erect stems bearing simple, serrate leaves. The dioecious inflorescences are green, bearing inconspicuous flowers from February to April. It characteristically forms dense, extensive carpets on the floor of woodlands and beneath hedgerows.

Maes-yr-Uchaf Wood is a small woodland and Site of Special Scientific Interest (SSSI), noted for its biological characteristics, in Monmouthshire, south east Wales.
Upper Wye Gorge is a Site of Special Scientific Interest (SSSI), noted for its biological and geological characteristics, around Symonds Yat in the Upper Wye Valley on the Wales–England border. The site is listed in the 'Forest of Dean Local Plan Review' as a Key Wildlife Site (KWS).
Hanger Wood is an ancient woodland and Site of Special Scientific Interest (SSSI) in the parish of Stagsden, Bedfordshire in the United Kingdom. Situated approximately one kilometre east of the village of Stagsden, the 24.12 hectares woodland was declared a SSSI in 1988, being described by Natural England as "one of the best remaining examples of wet ash-maple woodland in Bedfordshire". The name "Hanger" comes from Old English/Anglo-Saxon term for "wood on a hill" or "wooded hill", applied to Hanger Wood due to its situation on a northwest-facing slope of a narrow ridge. Commenting on the wood's character, A. Simco said in 1984 that "It has been strongly influenced by the geology and topography of the area, particularly by the south-west/north-east boulder clay ridge along which the parish boundary runs."
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.
