List of Sites of Special Scientific Interest in Avon

This is a list of the Sites of Special Scientific Interest (SSSIs) in the former county of Avon
Avon (county)
Avon was, from 1974 to 1996, a non-metropolitan and ceremonial county in the west of England.The county was named after the River Avon, which runs through the area. It was formed from parts of the historic counties of Gloucestershire and Somerset, together with the City of Bristol...

, which chooses a site because of its fauna

Fauna

Fauna or faunæ is all of the animal life of any particular region or time. The corresponding term for plants is flora.Zoologists and paleontologists use fauna to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess shale fauna"...

, flora

Plant

Plants are living organisms belonging to the kingdom Plantae. Precise definitions of the kingdom vary, but as the term is used here, plants include familiar organisms such as trees, flowers, herbs, bushes, grasses, vines, ferns, mosses, and green algae. The group is also called green plants or...

Geology is the science comprising the study of solid Earth, the rocks of which it is composed, and the processes by which it evolves. Geology gives insight into the history of the Earth, as it provides the primary evidence for plate tectonics, the evolutionary history of life, and past climates...

or physiographical features. Although the county of Avon no longer exists, Natural England still uses its former borders to mark one of its Areas of Search

Area of Search

Areas of Search are geographical areas used in the selection of Sites of Special Scientific Interest. In England these are largely based on the 1974–1996 administrative counties...

. As of 2006, there are 86 sites designated in this Area of Search

, of which 39 have been designated due to their biological interest, 39 due to their geological interest, and 8 for both.

Natural England took over the role of designating and managing SSSIs from English Nature

English Nature

English Nature was the United Kingdom government agency that promoted the conservation of wildlife, geology and wild places throughout England between 1990 and 2006...

in October 2006 when it was formed from the amalgamation of English Nature, parts of the Countryside Agency

Metropolitan and non-metropolitan counties of England

Metropolitan and non-metropolitan counties are one of the four levels of subdivisions of England used for the purposes of local government outside Greater London. As originally constituted, the metropolitan and non-metropolitan counties each consisted of multiple districts, had a county council and...

and as such the same approach is followed here, rather than splitting these sites between the Somerset and Gloucestershire lists. The data in the table is taken from English Nature in the form of citation sheets for each SSSI.
