The region of the upper Mosel Valley is situated in the South-east of Luxembourg and overs two ecological sectors; the Mosel Valley and the forelands of the Mosel. These are explained partly by a different geological underground. While the eastern part is dominated by Lias-formations from the Jura with wooded escarpments, the West is impressed by Keuper from the Trias with a wide and softly hilled landscape. All in all, the geology is very interesting and generates a very versatile and diverse landscape. The region is located in a climatically favoured area, which is distinct by its viticulture. The Mosel Valley is, with an average temperature per year of 9,5°C and average precipitations of 700 mm, even a bit warmer than the forelands with averages of 9 °C and 700-750 mm per year.

Because of its diverse landscape, the area is important for nature protection, which is focussed on the wetlands of the area, giving a habitat for many bird and amphibia species. You may also find many forest communities as well as a unique colony of the great horseshoe bat in the area. To protect this bat species, the enlargement of extensive grasslands, and therefore also calcareous grasslands, is contributing. The enlargement of calcareous grassland is reasonable as the area gives ideal conditions and remains of this type of grassland still can be found. Unfortunately these remains are threatened by more or less intense scrub invasion.
