Cognised existence: Nature protection areas are politically designated zones where biodiversity and natural heritage take precedence over other land uses. Their boundaries carry legal weight and are the primary input for conservation planning.

Question: What areas are designated for nature protection at a location?

OpenStreetMap — boundary=protected_area, leisure=nature_reserve

OSM maps protected areas globally. Coverage is linked to WDPA (World Database of Protected Areas) imports in many countries.

• OSM protected area boundaries may lag official updates.
• protect_class is not consistently tagged.
• For authoritative data consider: EEA CDDA (Europe), WDPA (global), or national environment agency sources.
