This is a list of the Sites of Special Scientific Interest (SSSIs) in Greater London, which is part of south east England. In geographic terms, the area is split by the River Thames. The London region has a population of 7,512,400 within an area of 1,579km², making it the second-largest populated region in the United Kingdom.[1] However, even though it is one of the largest urban conglomerations in Europe, almost two-thirds of London is made up of greenspace and wetlands, consisting primarily of extensive areas of green belt, large parks and the Thames basin.[2] As of 2007[update], there are 36 sites designated within this Area of Search, 18 of which have been designated for their biological interest, 11 for their geological interest, and 7 for both biological and geological interest.[3]
In England, the body responsible for designating SSSIs is Natural England, which chooses sites because of their Fauna, flora, geological or physiographical features.[4] Natural England took over the role of designating and managing SSSIs from English Nature in October 2006 when it was formed from the amalgamation of English Nature, parts of the Countryside Agency and the Rural Development Service. The data in the table is taken from English Nature's website in the form of citation sheets for each SSSI.[5]
