This study was accomplished in Nascentes do Garcia Natural Park, Blumenau city, Santa Catarina State, in order toevaluate the dynamics of the Submontain Atlantic Rain Forest, in the initial secondary forest, intermediate secondary and advancedforest stages. In 2001, 20 permanent sample plots of 10 x 20 m were installed, in each sucessional stage. In 2003, a new measurementwas done in the sample plots, when the changes in this mortality and ingrowth of all individuals with circumference > 15 cm weremeasured. The mortality, the ingrowth, and the relation ingrowth/mortality are bigger in the initial stages and decrease gradually withthe vegetation development. The pioneer species showed, in general, higher mortality taxes if compared to the ingrowth. The climaxspecies light-demanding showed best equilibrium between ingrowth and mortality. The climax species shadow tolerant showed aprogressive dynamic from the initial stage to the advanced stage. The ingrow, in the initial stage, was expressive in the pioneers andin the climax light demanding species. In the intermediate stage and in the advanced stage, the climax shade tolerant species and theclímax light demanding species presented higher ingrow.
