Phytosociological study of the magellanic deciduous forest in its northern boundary of distribution
The northern most stands of Nothofagus pumilio (lenga) and Nothofagus antarctica (ñirre) in the protected area of Vilches (35° 36' L.S. and 71° 03 ' L.W.) in the western slope of the Andean Mountain Range (VII Region of Chile) were studied.Nothofagus pumilio with discontinuous distribution...
