GCN - Strategic Opportunity Areas (England)

This dataset identifies areas where the addition of new ponds would benefit Great Crested Newt populations defined as strategic opportunity areas (SOAs). These England-wide dataset incorporates the SOAs for all regional areas. The attribute “Strategy_Area_Name” defines these areas..The details below describe how the SOAs are scored for each region

The core areas contain a pond density of 2+ ponds and are located within a 25m square where great crested newt presence has been predicted. Fringe areas contain a pond density of 1 and are located within a 25m square where great crested newt presence has been predicted or are within a 250m of a Core Area. Typically urban areas greater than 2ha (+400m buffer), roads (7.5m buffer), and rivers (+7.5m) have been excluded unless otherwise stated..

All scores are summed, scores ≤ 0 are not displayed. Higher scores are associated with darker colouration and represent a greater presence of suitable habitat features (density refers to the coverage of a habitat type with 250m of any 25m grid square):
