Drone seeding of a total of 140,000 Pinus Nigra seeds. "Unlike planting, with this action the tree will not be seen, but after a few years we will be able to see plants with a greater guarantee of survival...". As Fernando Bautista, AlVelAl's technical director of natural areas, points out, this method allows "the plants to invest all the energy accumulated in the seed to produce pivoting roots with a high capacity for deepening".
