Lambert's Castle is an Iron Age hill fort in the county of Dorset in southwest England. Since 1981 it has been designated as a Site of Special Scientific Interest (SSSI) on account of its geology, archaeology and ecology.
Possil Marsh is a nature reserve and Site of Special Scientific Interest, of both flora and fauna, within the city of Glasgow, Scotland. The reserve was once part of an extensive system of lochs and marshes which extended throughout much of lowland West Central Scotland. However, centuries of drainage and reclamation have resulted in the elimination of much of this system. Due to its geographic position, the marsh is particularly vulnerable from industrial and residential development. The reserve contains a monument for the High Possil meteorite, which fell there in 1804.
Sound Heath, also known as Sound Common, is an area of common land in Sound, near Nantwich in Cheshire, England, which includes heathland, grassland, scrub, woodland and wetland habitats. The majority of the area is designated a Site of Special Scientific Interest and a Local Nature Reserve.
Pow Hill Bog is a Site of Special Scientific Interest in the Wear Valley district of County Durham, England. It lies alongside Derwent Reservoir, approximately 2 km north-west of the village of Edmundbyers and adjacent to the Edmundbyers Common portion of the Muggleswick, Stanhope and Edmundbyers Commons and Blanchland Moor SSSI.
Red Moor is a nature reserve and Site of Special Scientific Interest (SSSI), noted for its biological characteristics, near Lanlivery in mid Cornwall, England, UK.
Rosenannon Downs is a nature reserve in mid Cornwall, England, UK, being designated Rosenannon Bog and Downs Site of Special Scientific Interest (SSSI), noted for its biological characteristics. The site supports a wide variety of flora and fauna and includes Bronze Age barrows. Conservation work is carried out on the site by the owners, the Cornwall Wildlife Trust.
Machynys Ponds is a Site of Special Scientific Interest (SSSI) in Carmarthenshire, Wales, designated in 1993 for its botanical features.
Allendale Moors is a Site of Special Scientific Interest (SSSI) in Northumberland, England. The upland moorland ridge site is listed for its heath, flush and upland grassland which provide a habitat for a nationally important assemblage of moorland breeding birds.
Arcot Hall Grasslands and Ponds is the name given to a Site of Special Scientific Interest (SSSI) near Cramlington in Northumberland, England, notable as the largest lowland species-rich grassland in North East England. The site is composed of grassland, heath, ponds, and associated damp habitats now rare in Northumberland.
Aules Hill Meadows is the name given to a Site of Special Scientific Interest (SSSI) in Northumberland, England. The site, listed since 1992, is a set of four traditionally managed northern hay meadows, now rare in Northumberland.
Bamburgh Coast and Hills is the name given to a Site of Special Scientific Interest (SSSI) on the coast of north Northumberland, England. The site is one of the longest-standing SSSIs in England, having been listed since 1954, and displays the interaction of a fluid magma rock, now known as the Whin Sill, interacting with older sedimentary rock. Coastal erosion at the site enables sections of the geological strata to be seen. In turn, the soil associated with the Whin Sill gives rise to a distinct pattern of vegetation which on its own merits is at this site found notable.
Campfield Kettle Hole is the name given to a Site of Special Scientific Interest (SSSI) in north Northumberland, England. The site is thought to be the remains of a kettle hole, a pond formed in the void remaining after a submerged glacial calf block melted. In contemporary times Campfield Kettle Hole is a mix of bog and pond.
Barrow Burn Meadows is the name given to a Site of Special Scientific Interest (SSSI) in north Northumberland, England. The site is a species-rich hay meadow of a sort now rare in Northumberland.
Beltingham River Shingle is the name given to a Site of Special Scientific Interest (SSSI) in Northumberland in the north-east of England, notable for an unusual community of flora tolerant to the high levels of naturally occurring heavy metals in the sediment of a section of the River South Tyne.
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.
New Hartley Ponds is the name given to a Site of Special Scientific Interest (SSSI) in south-east Northumberland, England. The site comprises six seasonal ponds listed for their vegetation and newt population.
Fallowlees Flush is the name given to a Site of Special Scientific Interest (SSSI) in mid-Northumberland, England. The steeply sloping site has calcium-rich springs supporting vegetation rare in the county.
