6 year cycle of evaluating condition of features on SSSI/SAC/SPA suite with a standard way of reporting condition but country led means of detecting it. Many features (e.g.: habitats, species) shared with other parts of the surveillance framework, but SSSI network is a significant part of the range/distribution for only a proportion of features. The Scottish contribution to this programme is produced by 'Site Condition Monitoring activities', while England, Northern Ireland and Wales use 'Common Standards Monitoring'.
