West Rigg Open Cutting is a Site of Special Scientific Interest in the Wear Valley district of west County Durham, England. It is a disused ironstone quarry, located just over 1 km north of the village of Westgate, in Weardale.
Sleightholme Beck Gorge – The Troughs is a Site of Special Scientific Interest in the County Durham district of south-west County Durham, England. The site covers a gorge in the valley of Sleightholme Beck between the hamlet of Sleightholme and the confluence with the River Greta, some 3 km upriver from the village of Bowes.
Smarts Quarry is a Site of Special Scientific Interest (SSSI) in Carmarthenshire, Wales, designated in 1987 for its geological features.
The Allen Confluence Gravels is the name given to a Site of Special Scientific Interest (SSSI) in Northumberland, England. The site, listed since 1968, has an 'outstanding assemblage of river margin invertebrates.'
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.
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.
Barelees Pond is the name given to a Site of Special Scientific Interest (SSSI) in north Northumberland, England. The site is a kettle hole, a deep pond formed in the void remaining after a submerged glacial calf block melted. Barelees Pond is illustrative of vegetative habitat evolution as peat sediment gradually fills the pond.
Bradford Kames is the name given to a Site of Special Scientific Interest (SSSI) in north Northumberland, England. The site is an esker, a ridge of glacial till deposited in the Pleistocene epoch.
Barrow Burn Meadows is 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.
Bavington Crags is a Site of Special Scientific Interest (SSSI) in north Northumberland, England. The site is an outcropping of the Whin Sill which gives rise to distinctive flora particular to the thin soil conditions on this bedrock.
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.
Brada Hill is a small hill escarpment near the coast of north Northumberland in North East England, designated as a Site of Special Scientific Interest (SSSI). The 2.4 hectares site is an outcropping of a local stone group, the Whin Sill, on which grows a range of flora representative of the thin, drought-prone soil conditions and influenced by the underlying geology.
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.
Burnfoot River Shingle and Wydon Nabb is the name given to a Site of Special Scientific Interest (SSSI) in Northumberland, North East England. Burnfoot River Shingle is a calaminarian grassland on the River South Tyne where the local flora is influenced by high levels of naturally occurring heavy metals. Wydon Nabb is an escarpment displaying the Haltwhistle Dyke, a magmatic intrusion of igneous dolerite set amidst sedimentary sandstone and shale.
Colour Heugh and Bowden Doors are two crag rock formations in north Northumberland in North East England, designated as a Site of Special Scientific Interest (SSSI). The 11.3 hectares site is described as "arguably the most impressive exposures of the early-mid Dinantian Fell Sandstone Group in the whole of northern England".
Longhoughton Quarry is a Site of Special Scientific Interest (SSSI) in north Northumberland in North East England. The site is a now disused quarry which yielded whinstone, a hard dark rock associated in Northumberland with the Whin Sill.
