Before mowing, the national alpine botanical conservatory (CBNA) conducted a comprehensive inventory of the hay meadow used to produce green hay, in order to assess the establishment of herbaceous species in the restored meadow.
Botanical monitoring of the restored site
Vegetation is monitored annually in 15 quadrants of 50 centimeters each side, distributed over a square of 10 meters each side along 3 transects (5 quadrants per transect). All plant species present are recorded, as well as the cover of vegetation and coarse elements (>2 cm). The frequency of species presence at the area scale, specific richness, and percentage of target species are calculated from these data.

Attitude of decision makers
The main opportunity was the involvement and motivation of the municipality of Saint Léger les Mélèzes to participate in the Sem' les Alpes programme. The animation and consultation work carried out in this programme has proved to be very important for the development of revegetation by alternative methods.

Policy, general governance and design targets
Many ski resorts are therefore carrying out revegetation operations on their slopes in order to stabilize the soil on the ski slopes and limit erosion. However, revegetation is generally carried out with exogenous seeds that are not fully suited for local conditions and biodiversity, and that also have a low species diversity. The runway has been remodeled, with its ground exposed. At the same time, a retention basin was dug upstream of the runway, causing a lot of soil material to be deposited on the runway. These materials were removed at the first rainfall, which made the ski slope very stony. Attempts to vegetate the ski slope following the work did not work, and it remained bare. The objectives of the prairie revegetation were to improve snow cover conservation and control erosion, while allowing the ski slope to be landscaped and grazed in summer. It was not grazed on the first 2 years to allow its correct rooting and installation.
