Dynamics of natural regeneration after disturbance in a remnant of Mixed Ombrophilous Forest in southern Brazil
This study evaluated changes in the structure for remnant Mixed Ombrophilous Forest recovering from logging, which ceased over 40 years ago. Regarding the dynamics of the floristic composition of natural regeneration, 18 species remained (23.38% of the total) and 27 new species entered (35.06% of th...
