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: grassland (+250m buffer), woodland (+250m buffer), within 100m-2500m range of a river, with a pH >6.5 and Phospherous >40. These suitable habitat features have been given a score of ‘1’. Arable land and Suburban areas have been given a score of ‘-1’. Urban areas greater than 2ha (+400m buffer), roads (7.5m buffer), rivers (+7.5m), Special Protection Areas (+500m), Special Areas of Conservation (+100m) and Ramsars (+100m) have been excluded. © Natural England [year], reproduced with the permission of Natural England, http://www.naturalengland.org.uk/copyright/. © Crown Copyright and database rights 2018.
