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%; distrance from woodland < 100m; woodland density 15 – 75%; arable density 0 – 25%; Distance from rivers <1500m; pH 6.75 – 7.25 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.
