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 within 250m and are located within a 25m square where great crested newt presence has been predicted.Fringe areas contain a pond density of 1 within 250m and are located within a 25km 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:The following suitable habitat features have been given a score of ‘1’:grassland density 10 - 66%distance from arable >125mdistrance from woodland  < 100mElevation 100 - 300mNearest pond < 100mpH 6 – 7distance from rivers 100-500mThe following unsuitable habitat features have been given a score of ‘-1’:urban density 50 - 100%Urban areas greater than 2ha (+400m buffer), roads (7.5m) and rivers (7.5m)  have been excluded.Full metadata can be viewed on data.gov.uk.
