What this layer shows
Bat records under an open licence. The great majority come from winter counts at fixed hibernation sites, so this layer says little about summer roosts, maternity roosts and flight lines, and the data holders deliberately blur sensitive species to grid squares of 1 to 10 kilometres. Where nothing is shown, either nobody looked or the record was not shared under a freely reusable licence, and nothing in this layer replaces a protected species survey or fieldwork. 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.

Natura 2000
The Natura 2000 network of the three Regions: the Walloon and Brussels sites, and the Flemish habitat- en vogelrichtlijngebieden. This is the free set, the one the map opens with everywhere in Belgium.
Desk study
What a consultancy or a notary checks first in Flanders: SBZ-H and SBZ-V with their sub-sites, VEN and IVON, Ramsar, nature reserves and natuurbeheerplannen, land-use designation and overdrukken from DSI, rights of pre-emption, protected heritage and archaeology, flood-prone land, signaalgebieden and drinking water protection zones. The rest of water, soil, land use and heritage sits in a set of its own.
