Dataset for: Assessment of grassland condition, Surface transect ring-survey records

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 assess the floristic composition of the grasslands and to determine the frequency of species consumed by vicuñas, undesirable species, and other types of non-forage cover (rocks, pavement, litter, etc.), a one-inch sampling ring was used along the 30-meter linear transects. A total of 100 records were taken, documenting the plant species and other types of cover.
