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 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.Higher scores are associated with darker colouration and represent a greater presence of suitable habitat features:grassland density 10% - 50%distance to deciduous woodland 0 - 200mconiferous woodland density 0% - 25%within 500m - 2000m of a riverThese suitable habitat features have been given a score of ‘1’.arable density 33.33% - 100%heather density 33.33% - 100%distance to nearest pond > 750mThese habitat features have been given a score of ‘-1’.Urban areas > 2ha (+400m buffer), roads (7.5m) and rivers (7.5m) have been excluded. Full metadata can be viewed on data.gov.uk.
