     notifies the landowner, the occupier (if different) and the local planning authority (plus relevant government departments and agencies);
  • Owners and occupiers are given time to lodge objections or make representations concerning the restrictions imposed on an SSSI;
  • The Board of Natural England considers these responses and decides whether to confirm or withdraw the SSSI notification.


The initial notification of a site is accompanied by a citation sheet, which outlines the reasons for the notification: the data in the following list is summarised from these individual citation sheets.

Reasons for notification as SSSI

Of the 88 SSSIs designated in County Durham, 67 have been designated for their biological interest, 16 for their geological interest, and five for both biological and geological interest.

Biological

Area covered

From its inception, English Nature classified sites using the 1974-1996 county system. As Natural England uses the same system, it is also adopted in the following list. As a result, some sites that lie within the ceremonial county of Durham and might therefore be expected to be listed here will be found instead in either the Cleveland or the Tyne and Wear lists.
