Hi bxl-forever, I did not modify the outline of what is drawn as nature reserve, because I have no reference for that.
The names I have added are the ones that are on the local panel and this panel is issued by official instances such as Leefmilieu Brussel and the Brussels-Capital Region.
These are also the names used by the CCN/CBN.
Let me know if anything still unclear.
Best regards,
Tom
