List of Sites of Special Scientific Interest in Mid and East Lothian

The following is a list of Sites of Special Scientific Interest in the Mid and East Lothian Area of Search, in Scotland. For other areas, see the list of SSSIs by Area of Search.

Site name	Photograph	Area	Date of designation	Location	Map	Citation	Description
Aberlady Bay	File:Aberlady Bay from Aberlady Point - geograph.org.uk - 5640708.jpg	582 hectares	14 July 1952	Template:Coord	Template:Efn	Template:Efn	Template:Efn
Bangley Quarry	Template:Efn	3.92 hectares	4 February 1991	Template:Efn			The site has a trachybasalt dyke that cuts vertically through the lava sequence and has large (up to 5cm) clear crystals of sanidine feldspar that shows Carlsbad twinning. The presence of the sanidine indicates metastable preservation, which is very rare and is attributed to rapid cooling of the rock. These specimens are the highest quality in Britain.
Barns Ness Coast	File:Barns Ness Lighthouse - geograph.org.uk - 5764542.jpg	258.68 hectares	30 April 1984	Template:Efn			The site contains Lower Carboniferous limestone that is rich in fossils so it can show a correlation between the Scottish Lower Carboniferous and the Northumbria Lower Carboniferous. It also contains a dissected raised beach platform that is of geomorphological interest along with uncommon habitats for the Lothian area like beach-head salt marshes and enriched dune grassland. It also has a diversity of wild flowers and locally rare plant species.
Auchencorth Moss	File:Auchencorth Moss. - geograph.org.uk - 72502.jpg	105.59 hectares	19 April 1991	Template:Efn			The site contains Sphagnum moss carpets which remain wet, which is a rare feature in the Lothian area because most has been degraded. Several species of Sphagna have been identified, and the rest of the site contains Calluna vulgaris, Erica tetralix, Deschampsia flexuosa, and cotton-grass.
Bass Rock	File:Bass Rock from south east.jpg	7.61 hectares	15 August 1983	Template:Coord			The site rises 107 metres above sea level and supports the largest single-rock northern gannet colony in the world. It numbers about 48,000 pairs and contains 22% of the UK's breeding population.
Bilston Burn	File:The Bilston Burn just before it flows into the River North Esk - geograph.org.uk - 2064868.jpg	16.59 hectares	11 March 1986	Template:Efn			The site shows major Dinantian sections that is Lower Carboniferous, proving much of the local Carboniferous succession. Named succession for coals and limestone have been proved along with fish bone-bed underneath the limestone, and is of great importance for comparison of sites in the Midland Valley. The ground flora has the characteristics of ancient woodland, which is one of few examples at Midlothian.
Black Burn	File:Black Burn - geograph.org.uk - 72393.jpg	31.53 hectares	16 January 1990	Template:Efn			The site contains dry valley slopes with grasslands of Juncus acutiflorus and traditional grazing has allowed sward with herb species and also allows numerous plants such as the Lotus pedunculatus. The unimproved grassland, marshy grassland and enriched undisturbed flushes are all declining in the area.
