ABOUT THE RESULTS Risk is not the same as compliance/classification. Risk should be linked to an activity/activities & provide a forecast based on predicted changes to pressures (e.g. to 2015) Risk categories are the same as used for Article 5 reporting o 1a- At risk o 1b- Probably at risk o 2a- Probably not at risk o 2b- Not at risk o Not assessed/not able to assess

WHAT ARE THE ASSESSMENTS BEING USED FOR ? Development of measures to help achieve WFD objectives Future revisions to our risk-based monitoring programme
