Auengebiete von nationaler Bedeutung
What this layer shows
Floodplains of national importance under Art. 18a NHG and the Floodplains Ordinance. The objects are to be preserved intact; the protection objectives include the plant and animal life typical of floodplains and, where sensible and feasible, the natural dynamics of water and sediment. Departures are allowed only for projects directly tied to the location that serve protection against the harmful effects of water or another overriding public interest of national importance, and they require protection, restoration or replacement measures. The cantons fix the exact boundaries.

Federal inventories
The inventories of national importance a project is measured against: BLN, floodplains, raised bogs and fens, mire landscapes, dry grasslands and amphibian breeding sites, with the hunting-ban areas, bird reserves, forest reserves, wildlife rest zones, Emerald and Ramsar sites and Pro Natura's reserves. The basis of every environmental assessment under the NHG.
Environmental assessment
Where an environmental consultancy starts a site assessment: the federal biotope inventories, forest reserves and wildlife rest zones, the state of the rivers, wildlife corridors and amphibian crossing sites, the sites of threatened mosses, and the groundwater protection zones, hazard map and polluted-site registers of the cantons that publish them openly.
