Chiroptères
What this layer shows
Bat observations shared under a CC0 or CC BY 4.0 licence. Location is most often degraded at source: the majority of these records carry an uncertainty of 1 to 6 kilometres, frequently the centre of a 5 kilometre grid square, so a point never marks a roost. Empty ground means that nobody has looked or that the data are not reusable, the display is capped at three hundred records per view, and none of this replaces a field survey. Where the publisher locates a record no better than a kilometre, it is drawn as a circle of that stated radius instead of a dot.
Not in the app's radius search: Observation records, not designations: an absence here is not evidence

Constraints
The constraints a consultancy checks first: Natura 2000 (the basis of the impact assessment), nature reserves, biotope orders, ZNIEFFs, classified sites, historic monument surroundings and PPR flood perimeters. It does not include each PPR's detailed regulatory zoning or the PLU rules: consult the planning document for buildability.
Nature and reserves
The protected natural spaces network: Natura 2000, the réserves naturelles (nationales, régionales, de Corse), the protection orders, the national parks with their cores, the regional and marine nature parks, the Ramsar sites and the wetlands.
