This dataset identifies areas where the addition of new ponds would benefit Great Crested Newt (GCN) populations. The core areas contain a pond density of 2 ponds and are located within a 1km square where GCN presence has been predicted. Fringe areas contain a pond density of 1 and are located within a 1km square where GCN 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 (*** features vary between clusters): grassland density (*** %), woodland density (*** %), Distance to deciduous woodland (*** m), Coniferous woodland density (*** %), Distance from rivers (*** m), Soil pH (***), Phosphorus (***), Arable density (*** %), Shannon Weaver Diversity (***) = ?1?. Arable land (*** density %), Heather (*** density %), distance to nearest pond (*** m), Soil Type (***) = '-1'. Urban Area (*** Ha [ *** m buffer]), roads (*** m), rivers (*** m) and Environment Agency Flood Zone 2 have been excluded.Full metadata can be viewed on data.gov.uk.
