On May 4 and 5, the EEZ-CSIC team evaluated the biodiversity of the pilot area of ​​Alcóntar in the areas burned in autumn (with grazing and without grazing).

Two methodologies were used:

1) evaluation of specific coverage and height of the vegetation within the square squares of one square meter that had been evaluated before and after the burning (8 squares per plot, 4 plots of 500 m 2 for each burned area – with grazing and without grazing);

2) evaluation of biodiversity using the “Point Quadrat” method in a 20 m transect in each 500 m 2 plot (total: 4 transects per burned area), with evaluations every 20 cm. Samples were also taken from the foraging parts of the main species to make the nutritive value in the burned area (sprouts) and in an adjacent unburned area. The selected species were: esparto (Macrochloa tenacissima), gorse (Genista scorpius), laston (Helictotrichon filifolium), broom (Retama sphaerocarpa), espantalobos (Colutea arborescens), zamarrilla (Helianthemum violaceus) and Bupleurum fruticosum.
