Abstract

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+ (i.e. there are 2+ ponds within 250m of any 25m square) where great crested newt presence has been predicted. Fringe areas contain a pond density of <2 (i.e. there are fewer than 2 ponds within 250m of any 25m 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 50 - 1000m arable density 50 - 100% urban denity 40 - 100% grassland density 5 - 50% distrance from woodland < 100m distance to nearest pond 0 - 150m These suitable habitat features have been given a score of ‘1’. distance from rivers 50 - 1000m grassland density 5 - 50% distrance from woodland < 100m distance to nearest pond 0 - 150m These suitable habitat features have been given a score of ‘-1’. arable density 50 - 100% urban denity 40 - 100% Urban areas greater than 2ha (+400m buffer), roads (7.5m), rivers (7.5m) and Environment Agency Flood Zone 2 have been excluded.
