Fitosociología de los Bosques de Nothofagus antarctica (FORST.) OERST. en la Cordillera Costera de Cauquenes (Chile)
The ñirre (Nothofagus antarctica) forests in the coastal mountain range of the province of Cauquenes (35° 49'-50' S, 72° 27'-28' W, Chile, VII Region) were studied. The region has a mediterranean climate and mesomorphic characteristics. Twenty three vegetation samples, following...
