List of Sites of Special Scientific Interest in Hertfordshire

This is a list of the Sites of Special Scientific Interest (SSSIs) in Hertfordshire, a county in the East of England region. In terms of size, the region extends from Norfolk, in the north, to the Thames estuary, in the extreme south,[1] and almost two-thirds of the county is rural.[2]

As of June 2013, the county has a population of 1,140,700[3] within an area of 1,634 km2 (403,770.2 acres), making it the 16th largest ceremonial county in the United Kingdom.[4]

As of 2014, there are 43 sites designated within this Area of Search, 36 of which have been designated for their biological interest and 7 for their geological interest.[5]

In England, the body responsible for designating SSSIs is Natural England, which chooses sites because of their flora, fauna, geological or physiographical features.[6] The data in the table is taken from Natural England's website in the form of citation sheets for each SSSI.[7]

For other counties, see List of Sites of Special Scientific Interest by Area of Search.
