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 25x25m square where great crested newt presence has been predicted.Fringe areas contain a pond density of 1 and are located within a 25x25m 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:Distance from rivers 100 - 1250mElevation 0 - 200mDistance from deciduous woodland 0 - 100mDensity of arable 0 - 33%Distance from urban > 350mDensity of grassland 10 - 60%Nearest pond 0 - 500mThese suitable habitat features have been given a score of ‘1’.Presence of coniferous woodlandPresence of heatherPresence of acid grasslandHave been given a score of -2Urban areas greater than 2ha (+400m buffer), roads (7.5m) and rivers (7.5m)Full metadata can be viewed on data.gov.uk.
