  • Tree population of the municipal, state and public forest ownership specified by main tree species and age classes, units of inventory.

  • The map of the protected natural forests in the Grand-Duchy of Luxembourg is the result of a cartography of private and public forests in the framework of which data on forest formations protected under article 17 of the amended law of the 19th January 2004 concerning the protection of nature and natural resources (Nature Protection Law) were collected. The cartography was compiled in 2014 and is based on phytosociological field inventories of all the forest formations in the Grand-Duchy, realised during the years 1992-2002. None of the data collected and mapped between 1992 and 2002 have been updated by further inventories or by verification in the field. The “2014” map of protected natural forests thus reflects the situation as recorded during the years 1992-2002. Due to natural developments and changes induced through forest management since the original inventories (around 20 years ago), the actual situation encountered in the field today can differ from that shown in the “2014” map. The map can therefore only serve as a support tool for forest owners in the framework of article 17 conform forest management of natural forests protected by Nature Protection Law. In any case, the information it contains must be confirmed and, if necessary, updated in the field. Some protected forest formations have not been mapped in the original cartography and are therefore not represented in the simplified map: i.e. forest borders, copses and conversion or transformation states of coppice to high forest. Neither are small-area biotopes such as sources, natural ponds, rock formations, and so on represented on the map. They are nevertheless subject to protection under article 17 of the Nature Protection Law. All forest formations that are not protected under article 17 figure on the map as seen on the topographic maps of the Administration du Cadastre et de la Topographie. The guidance and best practice note ("Leitfaden für forstliche Bewirtschaftungs- und Pflegemaßnahmen von geschützten Waldbiotopen"), available online on the site of the Ministère du Développement Durable et des Infrastructures ( ), contains forest management recommendations helping to avoid the destruction, deterioration or degradation of the protected forests.

  • subdivision of the country in biogeoclimatic areas according to the ecological classification method based on climate, constitution of the mother rock and the ground: 18 ecological sectors

  • territory of first degree of the regional outposts of the nature administration conformable to the grand ducal regulation of 11th june 2009 concerning the number and composition of the outposts of the nature administration.

  • areal units of the biological stations, intercommunal syndicates for nature protection

  • This layer contains information on potentially polluted sites (sites where use could have caused soil contamination). An entry in the database does not necessarily mean that the soil is polluted.

  • The present location map shows the distribution of wind turbines authorized by the Minister of the Environment under the legislation on classified establishments. Depending on the data availability, information on the installed power, hub height and diameter of the propeller can be consulted. "Autorisé" is the project of a wind turbine that has been authorized under the legislation on classified establishments, while "existant" is a wind turbine built by the constructor and according to the implementation report. It should be noted that the coordinates of existing wind turbines listed in the authorization files do not always correspond exactly to the coordinates of the actual locations of the wind turbines after construction, and may vary slightly depending on the construction. Where applicable, the coordinates of wind turbines validated by an official surveyor are indicated by an attribute.

  • Particulate matter consists of any particles suspended in ambient air. In general, they consist of a complex mixture of substances of different sizes and characteristics, depending on the origin of emissions. In addition to the measurements of particulate matter in the telemetry network, which are used to inform the population in real time, PM10 and PM2.5 particulate matter are also measured by the filter reference method. Differences between the results of telemetry network measurements and those obtained with the reference method are due to different measurement methods.

  • The geostatistical interpolation map shows in real time the most probable distribution of the pollutant fine particles (PM2.5) between the different fixed measurement points that make up the telemetric network of Luxembourg, this at a resolution of 1km2.

  • In 2018, the environmental administration organised a nationwide air quality measurement campaign in collaboration with 36 participating municipalities and myenergy. More specifically, it is a national measurement campaign of NO2 by passive tubes in the context of the national air quality program and the "Klimapakt Loftqualitéit". The campaign aims to raise awareness and inform municipalities and their inhabitants about the air quality in their respective municipalities, motivate municipalities to contribute to improving their air quality, and demonstrate the efforts undertaken by municipalities for future communications.
