, geological 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. As of 2006, there are 86 sites designated in this Area of Search, of which 38 have been designated due to their biological interest, 39 due to their geological interest, and 9 for both. 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

Until the 2010s, Natural England, which maintains the database of English SSSIs, kept the listing of counties as it was in 1974, but by 2015 they had updated their lists to reflect some later changes. However, even though Avon was abolished in 1996 it is still used as an area of search by Natural England, rather than being divided between the
