Introduction

• Trees outside the forest

– FAO define by default in terms of the forest, as follows: trees

growing outside the forest and not belonging to the category of

forests, forest lands, or other wooded land.

– Trees outside forests are located on "other land", such as

agricultural land, built-up areas such as settlements and

infrastructure.

– Trees play a constant or occasional but always specific role in

livestock production systems

• The dehesas.

– Agrosilvopastoral systems are characterised by the dispersion or

individual or grouped trees associated with animal grazing and

cultivated areas.

MATERIAL AND METHOD

• Land cover classes were separated firstly in

cultivated and non-cultivates areas.

• In the uncultivated areas we differentiated

between:

– Shrubs

– Pastures

– Forest

– Dehesa with Shrubs and pastures

– Dehesa with pastures

Conclusion

•Decrease of dehesa:

• Forest repopulations.

• Olive groves

(18)

Conclusion

• Changes in the dehesa

structure:

– Reduction of the cultivated

dehesa

– Increase in the denseness

of bushes and trees

(19)

Conclusion

• Reasons for the increase in the denseness

of bushes and trees:

– Abandonmed of the exploitation.

– Hunting activities
