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 (http://www.environnement.public.lu/forets/dossiers/pfn/documents/Leitfaden_7_11_2014.pdf ), contains forest management recommendations helping to avoid the destruction, deterioration or degradation of the protected forests.

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 geostatistical interpolation map shows in real time the most probable distribution of the pollutant ozone between the different fixed measurement points that make up the telemetric network of Luxembourg, this at a resolution of 1km2.

Wild boar hunting is permitted all year round, as well in open landscape as in woodlands (derogation to the grand-ducal regulations on hunting periods).

This layer contains the collection centres for wild roadkill and guts, as well as the openingg hours and contact.

The certification of forests is an instrument of voluntary market to promote the sustainable management of forests. The main object is the appreciation of the criteria of sustainable management. The certification proves the conformity of a product, the product "wood", with standards expressed of sustainable management through independent assessors and thanks to continuous revisions. Two systems of certification, FSC® and PEFC, are active in Luxembourg. The choice of a system falls individually to every forest owner.

Every year, the Environment Administration organises a nationwide ambient air quality measurement campaign in collaboration with the Klima-Agence and participating municipalities. More specifically, this involves a national campaign to measure NO2 using passive tubes as part of the national air quality programme and the "Klimapakt Loftqualitéit". The aim of the campaign is to raise awareness and inform local authorities and their residents about the air quality in their respective communities, to motivate local authorities to help improve their air quality, and to demonstrate the efforts made by local authorities with a view to future communications.
