Coed Cochion Quarry is a Site of Special Scientific Interest (SSSI) in Carmarthenshire, Wales, in which the geology of the site has preserved rare Precambrian fossils.
Crûg Farm Quarry is a Site of Special Scientific Interest (SSSI) in Carmarthenshire, Wales, for the geological records preserved in its limestone.
Cwm Twrch is a Site of Special Scientific Interest (SSSI) in Carmarthenshire, Wales.
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.'
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.
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.
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.
Barrow Meadow 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.
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.
Brunton Bank Quarry is a disused quarry now designated as a Site of Special Scientific Interest (SSSI) in Northumberland, North East England. The quarry exposes a base layer of the Namurian Great Limestone stratigraphic unit, including the Chaetetes Band, the fossilised fauna within which is of current geological interest.
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".
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.
