SSSI Impact Risk Zones
What this layer shows
Zones where certain development types may impact an SSSI: used by planners to decide when to consult Natural England.

In these presets
Species
Protected species and licensing context: great crested newt licence survey returns and eDNA pond results, priority ponds, the Botanical Value Map, SSSI units with their condition assessments, and SSSI Impact Risk Zones: the layer that tells you whether Natural England must be consulted on a planning application. Note that these are records of where people have looked, not a map of where the species are: an empty area may only mean nobody has surveyed it.
Planning
The constraints that shape a red line: SSSI Impact Risk Zones, Green Belt, the Flood Map for Planning zones and storage areas with present-day rivers-and-sea risk, Agricultural Land Classification (both the provisional national map and the more reliable post-1988 surveys), nutrient neutrality catchments, National Parks, National Landscapes and Local Nature Recovery Strategy areas. Useful for a constraints plan or an early feasibility check before any ecology is commissioned.
