Inventory of nature and landscape conservation areas of over-municipal importance

In the 1975 Planning and Construction Act, the authorities were required to draw up an inventory of natural and homeland protection objects for their area of responsibility. As a cantonal authority, the Office of Spatial Planning has prepared an inventory of natural and landscape conservation objects of supra-municipal (regional/cantonal) significance, which was established by the Government Council in 1980. The term nature conservation objects includes wet meadows, dry meadows and gravel pits, while under the term landscape protection objects geological-geomorphological objects, boulders, hexagonal slopes and linear trees (hedges, fieldwoods and creeks) are summarised. In wet and dry meadows, a distinction was made between the actual core zone of the object and an environmental protection zone. The delimitation of the objects was not carried out in a parcel-sharp manner. The inventory is binding on all authorities (municipal to national), i.e. it must be taken into account in planning in order to balance interests; however, it does not entail any restrictions on ownership under public law. The 1980 inventory is the most important basis for the drafting of protective regulations. It consists of a plan (scale 1:5'000) and a text in which the individual objects are described in more detail. In particular, in the field of pit biotopes (silk pits), some significant changes and deviations from the data levels have occurred since the 1980s. The data levels are therefore to be used with the necessary caution and interpretation, depending on the purpose of the application. For the first revision of the indicative plan in 1995, 80 supplements were drawn up to the inventory. These inventory additions, taken into account in the indicative plan, were not fixed as separate specialist inventory, or as revisions of the inventory80 and are therefore available as an independent spatial data level. These additions have been incorporated into the current guideline settlement and landscape.
