Innalzamento delle zone vegetative, più incendi e invasioni di organismi nocivi. È questo il futuro delle foreste in Svizzera, secondo un rapporto presentato lunedì a Birmensdorf (nel canton Zurigo) da esperti dell'ufficio federale dell'ambiente e dell'istituto federale di ricerca per la foresta, la neve e il paesaggio.
Non è detto — sostengono i ricercatori — che i boschi saranno in grado di adattarsi ai cambiamenti climatici e di continuare a fornire il proprio contributo (produzione di legno o protezione contro pericoli naturali) senza l'intervento dell'uomo.
Il "consiglio" per evitare il peggio è quello di eseguire il tempestivo rimboscamento in seguito a grandi incendi. Fra le altre cose, potrebbe essere importante rafforzare anche la diversità delle specie.
