Unitisation Boundaries

Designated sites in Wales include but is not limited to Sites of Special Scientific Interest (SSSI), Special Protection Areas (SPA), Special Areas of Conservation (SAC) and Ramsar sites. These sites have been divided into management units. This dataset contains the boundaries of these units and includes information such as designation type, unit name, unit area, national grid reference and former Countryside Council for Wales (CCW) regions. Digitising began in 2007 and is on going as and when new sites are created or existing sites are altered. The purpose of these management units is to have a coherent plan in order to manage sites in a practical manner to ensure that work is done to get sites and their corresponding features into a favourable condition, as per the requirements of the protected sites.

Datganiad

Management units are generally digitised using OS Mastermap 2006 (exceptions to this are noted in the MapInfo table). The data is then cleaned and entered into Oracle Spatial. When new protected sites are designated, or existing sites are amended, there can be a lag time for when the unitisation layer is updated to reflect the latest changes. Therefore this layers should not be used as the definitive source for showing protected site boundaries.
