Contemporary conservation mapping: 3 ingredients…. 1. Raw data 2. Derived data 3. Culture

Contemporary conservation mapping: 1. Raw data (Quality and accessibility).

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.

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).

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)

Contemporary conservation mapping: 2. Derived data (availability and ease)

Basic principle of model building in GIS is to build a grid. 50 meters for current models.

Models are based on Model-builder which is part of Arc 10 software and is based on the principles depicted in the second diagram.

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

Contemporary conservation mapping: 3. Culture (sharing best practice and open sourced systems).

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

Raw Data Derived data Culture

Raw Data Derived data Culture

Raw Data Derived data Culture

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
