14. When the Project started 18% of the Sussex part of the West Weald was
covered by Ancient Woodland (according to the provisional ancient
Woodland inventory). This compares to 8.7% for West Sussex.
15. Revised data (2009) shows that 19.2% of the Sussex part of the West Weald is
covered by Ancient Woodland (compared to 10.5% for West Sussex).

20. What has happened to the raw data since the West
Weald Baseline Report?
• Master map background is now standard, facilitating cross border working.
• Natural England has promoted habitat data standards which are now used
throughout the UK.
• Detailed Geological data now more readily available from the British Geological
Survey.
• Hydrological and Water Framework Directive data developing fast and more
accessible.
• Species recording less adhoc and more structured. Increase from 80,000 to
181,000 records in five years.
• More accessible Historical data (tythe and OS)
29. Basic principle of model building in GIS is to build a
grid. 50 meters for current models.
30. Models are based on Model-builder which is part of Arc
10 software and is based on the principles depicted in
the second diagram.

32. What is the trend in derived data since the
West Weald Baseline Report?
• More non-biodiversity raw datasets available to use
• Access to complex modelling tools through standard GIS
Packages
• More processing power from computers
• Technologists and conservationists working together
37. Has the bio-informatic culture changed since
the West Weald Baseline Report?
• More experience and best practice to be shared (across sectors)
• Mass of documentation available online
• Online systems facilitating data sharing
• Open source systems
• Developing Local Record Centre network and GIS facilities within
organisations
42. What does this mean for landscape scale
initiatives?
• Data to help shape conservation aspirations
• Products to support funding bids and decision
• Landowner advice targetting mechanisms
• Clear messages
• Decisions based on evidence
• Increasingly cost effective
