Layer description: In Luxembourg, there are a number of (inner-)urban green spaces that transport their cool air into the built environment at night. These so-called park winds, i.e. thermally induced balancing currents from an enclosed green space, occur on larger green spaces that are embedded in a significantly warmer environment. The winds emanating from the respective green spaces flow in almost all directions and extensively ventilate the surrounding built-up area. Most of these green spaces are also located on hills, so that the resulting surface winds are further intensified by the relief. Explanation: The present geodata are taken from the regional climate analysis of Luxembourg (GEO-NET & LIST 2021) which was published with the report « KLIMAÖKOLOGISCHE SITUATION IN LUXEMBURG“ - Modellbasierte regionale Klimaanalyse / (La situation au Luxembourg en matière d’écologie climatique) » by the Administration for Environment. Source: -> https://environnement.public.lu/fr/klima-an-energie/changement-climatique/klimaanalyse.html -> https://data.public.lu/fr/datasets/klimaokologische-situation-in-luxemburg-la-situation-au-luxembourg-en-matiere-decologie-climatique/ Abstracts: The Luxembourg regional climate, which is formed during a low-exchange radiative weather pattern in summer, was investigated using high-resolution computer-based modelling. In total, the model area is described with 8,272,693 grid cells, with information on terrain height, land use, structural height and degree of sealing stored for each grid cell. The urban climate model FITNAH-3D according to Groß (1992) forms the basic framework for the modelling. The input data and model results are based on a horizontal spatial resolution of 25 m x 25 m. The model results are presented in maps. The model results are presented in cartographic representations of the nocturnal temperature field, the nocturnal cold air flow field (4 a.m. in each case) and the thermal load during the day (2 p.m.) and concretised in the form of a climate analysis map. The main product of the work process is a planning recommendation map with an associated catalogue of measures. On the one hand, the map makes visible the graduated need for action to improve thermal comfort in summer in all living/working and recreational areas (“load area”) of the population in Luxembourg. On the other hand, the planning recommendation map also assigns a value to all green and open spaces in the country ("compensation area") with regard to the climate-ecological functions they provide. Notes: - The geodata are only to be used in the context of the specific considerations of the above-mentioned report (e.g.: basic data as of 2018, specific meteorological framework conditions). - The composition of the layers is based on the corresponding maps from the above-mentioned report. Even though these layers can be combined with any other layers from other thematic areas in the geoportal, it should be noted that these representations can easily lead to misinterpretations. - Detailed explanations of this layer and the modelling methodology can be found in the sources mentioned above. - The assessments of the planning recommendation map are based on the climate-ecological functions without taking into account the concerns of other sectoral plans, i.e. the planning recommendation maps represent weighting material obtained from a climate perspective.

This map shows the built and functional amphibian culverts in the country. These are permanent structures that allow amphibians to safely cross a road to reach their breeding grounds (aquatic environments / still waters). During their breeding season (mid-February to mid-April), thousands of amphibians cross roads in numerous waves of migration. These roads, which were once deadly crossing points, are now adapted to the migratory flows of amphibians.

A terrain that has been destroyed to the point, that no elements of cultural heritage features can be preserverd. It is not part of the ZOA.

The aim of old wood island ist to maintain and foster forest ecosystem services. In particular, this means preserving endangered biocenoses associated with old and dead trees by maintaining pockets of old wood in stands. In these old wood islands all trees must be preserved, including standing or fallen dead trees. The definitions and specifications related to old wood island can be found in the Articles 14 and 16 of the amended règlement grand-ducal modifié du 12 mai 2017 instituant un ensemble de régimes d’aides pour l’amélioration de la protection et de la gestion durable des écosystèmes forestiers.

The forest stand is the smallest unit of the forest inventory. It subdivides the forest compartments (parcelles) into smaller sections (parquets) with similar forest structures. The forest stand map visualises the forest area that differs from the neighbouring forest parts in terms of structure, age and tree species.

Die Gebiete stellen die Brutreviere des Steinkauzes von 2017 bis 2021 dar. Die Daten wurden im Rahmen des Monitoringprogramms 'Steinkauz' der biologischen Stationen SIAS, Sicona sowie Mëllerdall erhoben und von der Centrale ornithologique natur&ëmwelt verarbeitet.
