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 density 10 - 50%
woodland density 10 - 60%
Distance from rivers <1500m
Shannon Weaver Diversity -1.5 to -0.6
These suitable habitat features have been given a score of ‘1’.
Arable land (density 50 - 100%) has been given a score of ‘-1’.
Urban areas greater than 2ha (+400m buffer), roads (7.5m), rivers (7.5m) and Environment Agency Flood Zone 2 have been excluded. © Natural England, 2022
