Dataset for: Assessment of grassland condition, biomass and digestibility of plants

The study was conducted in the community of Picotani, in two vicuña management sectors: Tambojarkas (TAM) and Chalhuani (CHAL). A total of 10 sites were evaluated, 7 within Chalhuani and 3 within Tambojarkas. In each site, three 30-meter linear transects were established, oriented to the north, southeast, and southwest. Along each transect, characteristics related to grasses and vegetation cover in the area were assessed, ranging from areas with low cover (due to overgrazing) to areas with high vegetation cover (less impacted sites). To evaluate the digestibility of the grass biomass present at the sites, a composite sample of 250 grams was collected by gathering plants from 5 subunits distributed along each linear transect. The samples were sent to a laboratory, where they were dried at 60°C for 48 hours in an oven in order to determine the dry matter content and the amount of digestible leaf.
