Camino Photo of the Day: Tree Farm?

We saw numerous stands of trees like this: all arranged in rows and grids. They exist all along the Camino, from Navarra right through into Galicia. I can only presume that they are tree farms, though this one here out on the Meseta is perhaps not in the most expected place.
