Eldiario.es states that the affected area in the CAV is as large as 133,000 football fields. As you will recall, the Basque Government and the Basque deputies want to fumigate pine trees with cuprous oxide, but the Spanish Ministry of the Environment has denied them permission to do so by air and now the Basque institutions want fumigation to be done by land.
Cuprous oxide is intended to be used experimentally on 1,050 hectares and fumigation can then be extended to other locations.
