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 a radius) and are located within a 25x25m grid square where great crested newt presence has been predicted.Fringe areas contain a pond density of <2 and are located within a 25x25m grid 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:Arable density 0 - 33%Grassland density (including fen) 10-75%Distance from grassland (including fen) 0-100mWoodland density 10-33%Distance from woodland 0-100mDistance from rivers 100-1000mElevation 0-150mpH 6.75-7.5These suitable habitat features have been given a score of ‘1’.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.
