The data presented here involves percentage cover of plant species (excluding lichens), litter, deadwood, bare soil, rocks, gravel and water inside nine 20 m by 20 m plots that were subdivided into 100 2 m by 2 m subplots. The nine plots cover three vegetation subtypes (‘pure’ natural grassland, sparsely vegetated ‘rocky’ grassland, and wetland) in each of three valleys (Bardoney, Colle de Nivolet and Levionaz) in Gran Paradiso National Park (Italian Alps) between 2200 and 2700 meters a.s.l. The vegetation survey was conducted at the peak of the yearly vegetation developement during August 2015. The plots’ boundary lines were North-South and East-West aligned according to UTM coordinates. The GPS coordinates of the plots’ corner points are given in the reference system WGS 84.

Vegetational description of inner Venter-valley and outer Rofen-valley along an altitudinal gradient from 1695 m to 2865 m a.s.l. Vegetation records were made in plots according to minimum areal of Braun-Blanquet (1964) In sum, 229 vegetation records were made (one record=one plot). Also ecological indicator-values are given. Ten vegetation associations were recorded, altitude and aspect were the most important criteria for the determination of different vegetation types. GPS-data were taken from googlemaps, according to the study site given in the report (Diploma-project).
