Federal Inventory of Floodplains of National Importance - Appendix 2

Floodplains, namely natural habitats in the flood zones of watercourses, are in decline. The scientific inventory of floodplains was commissioned by the FDHA in May 1981 and compiled by vegetation research group of the Swiss Federal Institute for Foresty (now FSL). In accordance with Article 18a of the Federal Act of 1 July 1966 on the Protec-tion of Nature and Cultural Heritage (NCHA), which came into force on 1 February 1988, the Federal Council designates biotopes of national importance, assesses their situa-tion and sets conservation objectives for them. However, this occurs after the cantons have been heard. As the second federal inventory under Article 18a NCHA, in 1992 the Federal Council implemented the Federal Inventory of Floodplains with 169 floodplain sites. It has been expanded in 2001, 2003, 2007 and 2017. Between 1995 and 1997, the Inventory of Glacier Forelands and Alpine Floodplains (IGLES), a scientific inventory, developed the bases for the first expansion. Currently 326 objects are contained in the inventory and protected by law.
Invasive alien plants - map of the potential area Ludwigia peploides

The set of invasive alien plants shows the maps of the potential areas of 56 alien plants species present in Switzerland as well as some invasive species present in neighboring countries with the potential to reach Switzerland. The maps are the result of model-based tool to anticipate the spread of invasive alien plants listed on the Swiss Black and Watch list. The model is using occurrence data from GBIF (Global Biodiversity Information Facility), current climate data from Worldclim(1 km resolution) and occurrence data from InfoFlora combined with climate data from the WSL (100 m resolution).The maps with 100 m resolution utilize additional necessary variables including landuse and geology.
Swiss National Park and parks of national importance (Perimeter)

The dataset contains the protected area of the ‘Swiss National Park’, which is protected in accordance with the National Park Act of 19 December 1980 (SR454) as well as park projects registered with the FOEN based on the Federal Act on the Protection of Nature and Cultural Heritage (NCHA), which was revised on 1 December 2007. It defines three categories of parks of national importance: national parks, regional nature parks and nature discovery parks. Depending on the status of the project involved, the park regions can apply for the ‘candidate for the development of a park’ label or the protected ‘Swiss park’ label for operational parks. Parks of national importance help with the protection and upgrading of outstanding natural habitats. The parks also promote the economic development of a region.
Federal Inventory of Landscapes and Natural Monuments

Article 5 of the Federal Act of 1 July 1966 on the Protection of Nature and Cultural Heritage (NCHA) orders the Federal Council to compile inventories of sites of national importance (federal inventories). The cantons must be heard when these inventories are enacted. The Federal Inventory of Landscapes and Natural Monuments of National Importance (ILNM) is the first federal inventory under the NCHA. The preliminary stage is the CLN Inventory (Inventory of Landscapes and Natural Monuments of National Importance), a reference whose first edition was released by private organizations in 1963 and has been periodically expanded and revised. The ILNM inventory has gradually taken legal effect. To date, the Federal Council has approved four inventory development series: the first series in 1977 with 65 sites; the second series in 1983 with 54 sites; the third series in 1996 with 33 sites and 11 revised sites; and the fourth series in 1998 with 9 sites and 15 revised sites. In the 2017 revision a surface exchange between the objects 1605 and 1606 was made.

National Ecological Network REN, watercourses / lakes

The National Ecological Network (REN) was developed in close collaboration with cantonal authorities for the protec-tion of nature and landscapes. It issues a technical/sciencific report that presents the Swiss landscape from an ecological perspective. It shows the divisions and connections between habitats on maps in a scale of 1:500,000 and 1:100,000 and considers not only the current situation, but also the potential of the landscape. This foreward-looking, holistic approach provides a total picture of the large ecological networks in the country. Maps of specific networks show the corresponding core and distribution areas as well as the continua and corridors of the 5 specific networks. The network situation of each specific network is illustrated in another series of maps.

Federal Inventory of Amphibian Spawning Sites of National Importance - Shifting Sites

There are currently 19 different amphibian species that live in Switzerland, and nearly all of them are included in the Red List of Threatened Species. The areas that contain wetland habitats have shrunken to less than one-tenth of their original size in the last 100 years, which is why remaining habitats must be protected. Most species prefer small still bodies of water, such as pools and ponds, for spawning. In addition to small pools and major wetland complexes, gravel and clay pits make up a large portion (approximately one-fifth of all objects) of the inventory. Due to their use, they have developed into nature-near sites that should be protected. The stationary objects are divided up into different spawning sites: Site A implies conservation sites. Site B includes narrower land habitats and buffer zones. These areas are mostly used for agriculture and forestry. Shifting spawning sites include used pits, in which the dynamic condition for conservation of future amphibian stocks should be preserved. As the fourth federal inventory under Article 18a NCHA, in 2001 the Federal Council implemented the Federal Inventory of Amphibian Spawning Sites with 701 sites. The inventory was expanded in 2003, 2007, 2017 and 2025 and now contains 969 objects.
NaiS-Weiserflächen und Beobachtungspunkte SuisseNaiS

Weiserflächen sind gemäss kantonalen Konzepten angelegte Untersuchungsflächen im Schutzwald. Sie sind ein Instrument der Erfolgskontrolle gemäss der BAFU-Vollzugshilfe «Nachhaltigkeit und Erfolgskontrolle im Schutzwald» NaiS (2005) und deren Betrieb ist Qualitätsindikator im Teilprogramm «Schutzwald» in den Programmvereinbarungen im Bereich Wald zwischen Bund und Kantonen. Beobachtungspunkte sind weniger formalisierte Untersuchungsflächen, auf denen z.B. anhand von Zeitreihen von Fotos jedoch auch spannende Erkenntnisse gewonnen werden können.

Inventory of historical routes in Switzerland of regional and local importance

The inventory of historical routes in Switzerland (IHR) contains comprehensive information about the course of the historical routes, their history, their condition and their importance in terms of the Natural Culture and Heritage Act (NCHA). In addition to objects of national importance, which are recorded in the federal inventory (objects with visible historical substance) and as supplementary information (objects with little or no structural substance), the IHR also includes objects of regional and local importance. These objects can be identified by the cantons as being important during the cantonal legislative process, the planning process or in other appropriate ways. They can be included in the electronic publication managed by the Federal Roads Office (FEDRO), even if the cantons cannot provide a definitive designation. Until a definitive designation of this kind is supplied by the cantons, the entries are based on provisional estimates by the Swiss Confederation. The publication of these objects which have not yet been given a definitive designation by the canton in question is justified because of the importance of this for the assessment of financial aid (Article 12 of the ITRO) and interventions (Article 7 of the ITRO).

Federal inventory of historical routes in Switzerland (IHR)

The inventory of historical routes in Switzerland (IHR) contains comprehensive information about the course of the historical routes, their history, their condition and their importance in terms of the Natural Culture and Heritage Act (NCHA). The IHR consists of two parts: the federal inventory and the additional historical routes (Ordinance on the Federal Inventory of Historic Swiss Transport Routes (ITRO), Article 3). The objects of national importance with visible historic substance make up the legally protected federal inventory. Objects which are of national importance in a historical context but which have no or little structural substance are not included in the federal inventory. Numerous objects which have been designated by the cantons as being of regional or local importance also form part of the IHR but not of the federal inventory. You can find more information about the inventory via the following link: http://www.ivs.admin.ch/. The complete dataset of the inventory can be displayed in the following WebGIS application and also downloaded: http://ivs-gis.admin.ch (see Article 4 of the ITRO).
Location and surrounding areas in accordance with the Major Accidents Ordinance in the area of the motorway

The Major Accidents Ordinance (MAO, SR 814.012) aims to protect the population and the environment from severe damage caused by major accidents. It stipulates that the owners of a transport route, an enterprise, or a pipeline facility must independently implement safety measures and governs the control and assessment procedures carried out by the authorities. The MAO applies to transit roads as defined in the Ordinance on Transit Roads, on which dangerous goods are transported or handled in accordance with the Ordinance of 17 April 1985 on the Transport of Dangerous Goods by Road (SDR) or the corresponding international agreements (ADR). According to Article 1 of the Ordinance on Transit Roads, transit roads are open to general through traffic. These include motorways, expressways, and main roads.
Snowshoe trails

The ‘Snowshoe trails’ dataset includes the best selection from SwitzerlandMobility (thick lines) and the other signposted trails from the cantons. This selection is coordinated with the Swiss Hiking Trail Association, the cantons and the Principality of Liechtenstein. This is currently (as of 12 November 2025) an initial data set containing the following information: SwitzerlandMobility trails throughout Switzerland, other signposted trails in the cantons of Jura, Schwyz, Graubünden and the Principality of Liechtenstein. No liability is accepted for the accuracy, completeness or up-to-dateness of the route and trail data, and any liability for the use of this data is excluded. The signage and the weather and trail or route conditions on site are decisive.
Settlement

The ‘Settlement’ is a geodata set of the settled landscape from a spatial development perspective. The data set serves as a geometric reference for various indicators in spatial observation. What is built for residential, work or leisure purposes is considered to be settled. This includes, in particular, the buildings and their surroundings, as well as the adjacent roads and transport infrastructure for their direct access. Any gaps that extend over more than 1500 m2 remain as such. The data layer is based on data from the topographic landscape model of swisstopo and the FSO's Register of Buildings and Dwellings. The data is updated and published annually. The time series from 1919 can be viewed as a time journey at map.geo.admich.ch and downloaded as yearly updates at https://data.geo.admin.ch/browser/index.html#/collections/ch.are.siedlung.
Housing inventory and secondary homes rate

The apartment inventory map service shows the status in blue primer of the municipalities that are subject to the building regulations of the Second Housing Act (ZWG, SR 702) and are only allowed to set up second homes under strict conditions (ZWG Art. 7ff.). The Second Homes Act defines the limit of a second home proportion at 20 per cent. The Second Homes Act obliges all Swiss municipalities to create an annual apartment inventory to calculate the number of proportion of second apartments. The basis for this is the Swiss Federal Register of Buildings and Dwellings. The Swiss Federal Register of Buildings and Dwellings is maintained by the municipalities and evaluated by the Federal Office for Spatial Development by 31.12. The Federal Office for Spatial Development will publish the apartment inventory and number of second apartments at the end of March. Municipalities whose second apartment share in March was under or over the limit of 20 per cent will be subject to a procedure to check the second apartment share. The list of the state of proceedings (status) will be updated at the end of October. The percentages of the apartment inventory will remain unchanged until the next publication of the apartment inventories at the end of March, as the exact values ​​do not always have to be determined in the examination procedure for the decision below or above 20 percent second home share. For more precise information, the municipalities are responsible for ongoing proceedings. The municipalities have to show the total number of apartments and first apartments in the apartment inventory, however, there is no obligation to declare first apartments, equivalent apartments or second apartments as such in the RBD. Therefore, the data from the apartment inventory regarding second apartments cannot be compared with data from other municipalities.
Cities and conurbations which qualify for subsidies

The list of cities and conurbations which qualify for subsidies shows which municipalities are entitled to federal subsidies within the framework of the Urban Transport programme (in accordance with Annex of the DETEC Ordinance on the Urban Transport Programme [PAVV, SR 725.116.214]). The basis for the list shows the definition of “Spaces with an urban character” from the Federal Statistical Office, FSO (2012). This includes the right to subsidies for all municipalities that are entitled to subsidies based on the definition of a conurbation from 2000. The number of adjoining communities are reduced in accordance with the definition by the Federal Statistical Office, FSO in 2012, through the use of statistical criteria. The municipalities of Sarnen and Appenzell as canton capitals are also included in the list of cities and conurbations which qualify for subsidies. Small adjustments were made with realignments and fillings in the gaps. The update dated 1 August 2025 is based on the 2020 agglomeration definition and includes the proposals from the cantons and agglomerations regarding the inclusion or removal of municipalities.
Areas worth examining from the Confederation's point of view for ground-mounted photovoltaic installations of national importance

The areas worth examining from the federal government's perspective provide initial indications of which areas could be considered as suitable areas in accordance with Article 10 of the Energy Act. The designation of these areas is based on the method used in the document "Freistehende Photovoltaikanlagen: Methodische Grundlage des Bundes" (Ground-mounted photovoltaic installations: methodological basis of the Confederation; published in german and french). The areas identified cannot be regarded as a sufficient or exclusive prerequisite for the spatial planning designation of suitable areas for solar installations of national importance or of zones for solar energy use under cantonal law. The relevant planning work by the cantons (or municipalities) is either underway or still to be carried out. This map does not prejudge any decisions made by the planning authorities in this regard. This dataset is designed for a scale of 1:25,000 or smaller. For an overview of Switzerland, please refer to the dataset "ratio areas worth examining". The two datasets complement each other and provide different information from a national or regional perspective. This dataset has an advanced search function. However, no additional information is available for cells that do not belong to the areas under consideration (i.e. urbanised areas and transport areas, large bodies of water and forests).
