The original concept at 'Auria' was to plant trees over underground streams so they could access more water in a dry climate, however, endemic trees that have evolved to grow in dry climates do not like such positions! Planted in such locations, they bend over the underground streams. With a view to growing food, an experiment was undertaken in 2017 with exotic species of trees which it was felt would appreciate such locations, but it was a failure. The trial involved: olives, almonds and apricots for food - and carobs and cork oak - for stock food and cork.
