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:pH 6.75-7.5Density of grassland 10-66%Distance from woodland <100mShannon-Weaver diversity -1.5 to -0.6Where drainage is classed as Impeded, Naturally Wet or WaterThese suitable habitat features have been given a score of ‘1’.Density of arable 50-100%Has been given a score of ‘-1’.Land classification is Acid Grassland or BogHas been given a score of ‘-2’.Urban areas > 2ha (+400m buffer), roads (7.5m) and rivers (7.5m) have been excluded.Full metadata can be viewed on data.gov.uk.
