They contrast with the introduced Australian species of the eucaliptus. Much like the heated debate that has been foregoing for years in the Spanish country. Eucaliptus was introduced on the XIX century and since then it has adapted and spread to the Galician soil. The controversy is between the paper industry and the ecologists fighting for better forestal planning as this foreign species threatens to kill this beauty.
