Effects of diet selection by goats grazing on the vegetation of a protected pine forest in Doñana Natural Park (SW Spain)

We investigated the relationship between feeding selection by goats and changes in plant species abundance in the shrubland of a pine forest in Doñana Natural Park along three years. The abundance of the shrub species was measured using the point-intercept method. Goat preferences for shrub species...
