Scroll down, or use links in 'Other sections' box, to find topics grouped by the five domains. Under each domain, the topics are grouped by the relevant environmental framework category (pressure, state, impact) and questions that ask "What are we trying to find out?". The provisional list of statistics that will be available are listed under each topic.

Download the PDF from 'Available files' to see the topics displayed in a table in A3 format. If you have problems viewing the file, see opening files and PDFs.
