Environmental Monitoring Networks

Swiss environmental monitoring networks record the state of all natural resources. Divided into themes, this overview shows the start date of each monitoring system, its goal and the organisation that collects the data. The start dates of monitoring, the number of monitoring sites, where possible, the data collection rate and the competent institutions are shown in parentheses.


Hydrological data show the state of lake water and river discharge (1963; 260 basic gauging stations; Hydrology Division, FOEN.

The Swiss National River Monitoring and Survey Programme (NADUF) monitors developments in water content in selected Swiss rivers (1972; Swiss Federal Institute of Aquatic Science and Technology, Eawag).

The Swiss National Groundwater Quality Monitoring Network (NAQUA) monitors the state and development of groundwater resources (1997; 500 monitoring sites; cantons and Confederation).

The Swiss National Surface Water Quality Monitoring Programme (NAWA) monitors changes in water levels and damages to the structure of bodies of water (2011; cantons and Confederation).

Forest/natural hazards

Swiss forestry statistics collect data from forestry operations and private forest owners, timber use and planting (1887, online 1975; annually; Swiss Federal Statistical Office, BfS).

The Swiss National Forestry Inventory (NFI) collects basic data on the changes and state of forests (1983; 10-year cycles; Swiss Research Institute for Forests, Snow and Landscapes, WSL).

The Sanasilva Inventory surveys crown condition as an indicator of the health of trees (1985; annual; WSL).

The Swiss Long-term Forest Ecosystem Research Programme monitors external influences and their effects on forests (1994; 19 research plots; WSL).

TreeNet researches forest reactions to climate change (2009; 6 sites; continuously; WSL, ETH Zurich, Institute for Applied Plant Biology, IAP).

StorMe, a natural event register, documents past natural events and provides information about areas at potential risk (1996; cantons).


Swiss fisheries statistics provide information about the changes and state of fisheries (1931; annually; cantons).

The Wild Bird Monitoring Programme monitors changes in threatened species of wild birds (1950; Swiss Ornithological Institute).

The Red Lists of Threatened Species list the most vulnerable species that require action (1977; various sources).

The purpose of Biodiversity Monitoring (BDM) is to monitor biological diversity in Switzerland (2001; depending on the indicator, anywhere from one hundred to 1,600 sampling areas; coordinated by the FOEN).

The Landscape Monitoring Switzerland programme (LABES) documents the changes and state of Switzerland’s landscapes (2008; 34 indicators; FOEN/WSL).


The Swiss National Air Pollution Monitoring Network (NABEL) measures air pollution (1968; 16 monitoring sites; Swiss Federal Laboratories for Materials Testing and Research, Empa).

The Swiss National Emission Information System (EMIS) collects data on emissions from various sources of air pollutants and greenhouse gases (ca. 1985; publication twice annually; Confederation).

The Accompanying Environmental Measures Monitoring Programme shows the environmental pollution caused by the transport of goods along the north-south axis (2003; 6 checkpoints; Confederation and cantons).

SonBASE – GIS-Noise Database of Switzerland provides detailed information about the noise pollution caused by various carriers (2009; Confederation).


The Swiss Soil Monitoring Network (NABO) measures soil pollution (1984; annually; Agroscope).


Swiss waste statistics provide data on changes in waste accumulation (1992; annually; various organisations and the Confederation).

The Swiss Pollutant Release and Transfer Register (SwissPRTR) provides information on pollutants and wastes from facilities and diffuse sources (2007; annually; facilities).

ECOGEN, a public register, provides information on research with genetically modified or pathogenic alien organisms subject to contained use (2009; continuously; universities).


The Swiss Greenhouse Gas Inventory measures all relevant climate gases and related carbon according to UN guidelines (1990; annually; Confederation).
