[1] The designation is classified by Natural England (the non-departmental public body of the UK government responsible for ensuring that England's natural environment is protected) as being a 'Local Site' designation,[2][3] though sites can also be of a regional and national importance.
[6] They are seen as important sites for "monitoring the health of the natural environment"[7] by central and local government bodies.
[4] An affirmation of the importance of County Wildlife Sites – and indeed all other sites with a designation in the 'Local Sites' category – can be found in Circular 06/05: Biodiversity and Geological Conservation – Statutory Obligations and Their Impact Within The Planning System,[3] and their role in helping the UK to meet national biodiversity objectives was recognised in Planning Policy Statement Nine.
[4] The latter affirmation of their importance in biodiversity conservation resulted in a strengthening of the presumption against development on County Wildlife Sites following the Natural Environment and Rural Communities Act 2006, which requires public bodies to 'have a regard for the conservation of biodiversity'.
For example, Suffolk Wildlife Trust offers 'advisory visits' to give guidance to site owners about the kind of conservation work they should be undertaking,[4] whilst the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire regularly surveys and undertakes volunteer work on County Wildlife Sites.
