Project executed by ARBA Cartagena in the area of "Camino del 33", in the Mining Park of La Unión (Murcia). The proposal consists of the restoration of the climax vegetation of the Sancti Spíritu, through the planting of Tetraclinis articulata forests, an Ibero-African habitat whose conservation is considered a priority for the European Union. The project aims to plant 4500 trees and shrubs in an area of 3.0 ha owned by La Union Town Council and another 1.5 ha of private property. The team is made up entirely of volunteers who dedicate their free time to this non-profit work.
