Dehesa and Production

There's a presentation available on the how the Spanish use the Dehesa to produce livestock. I haven't seen much online about what they do, so I thought it was worth posting about.

As the presentation makes clear, their pigs are primarily crossbred, outdoors only at the end of their lives and they are ringed. Those are all optimizations that allow them to raise more pounds of Iberico for less money and less environmental damage.
