Recursos pascícolas de la dehesa extremeña. Primeros datos para la modelización de su gestión

The ecosystem “Dehesa” is considered as a good example of balance between the use of natural resources and the preservation of environmental values, therefore, its study requires special consideration. One important aspect to take into account to handle this ecosystem is the management of pastures and their production.
