This dataset identifies areas where the addition of new ponds would benefit Great Crested Newt populations. The core areas contain a pond density of 2+ ponds and are located within a 1km square where great crested newt presence has been predicted. Fringe areas contain a pond density of 1 and are located within a 1km square where great crested newt presence has been predicted or are within a 250m of a Core Area. Higher scores are associated with darker colouration and represent a greater presence of suitable habitat features: grassland density 25% - 75% distance to woodland 0 - 100m arable density 0 - 50% within 100m - 1500m of a river a pH 6.5 - 8. These suitable habitat features have been given a score of ‘1’. Urban areas greater than 2ha (+400m buffer), roads (7.5m), rivers (7.5m) and Environment Agency Flood Zone 2 have been excluded.Full metadata can be viewed on data.gov.uk.
