RESUMO

Due its altitudinal amplitude, the Serra do Mar State Park (PESM), shelters a variety of physiognomies of the Dense Ombrophylous Forest, such physiognomies are distributed along the level quota in a standard way. This work aims to evaluate the contribution of the moist deposition through the rain, in the distribution of these physiognomies. In order do make the study in different altitudes possible, two PESM administrative nucleus were chosen: the Picinguaba nucleus, the only one among these ones that reaches the sea level, and the Santa Virginia nucleus which contemplates the highest quotas of altitude and consequentially, the forest formations related to them. It was observed in Picinguaba a lower rate of nitrogen and carbon deposition. The electrical conductivity of the rain water was higher in Picinguaba, putting into evidence that other elements, such as chlorine, sodium, magnesium, and others are also deposited in higher rates in Picinguaba. Thus, the variation in the forest physiognomies along the altitudinal gradient of Serra do Mar could be, in part, related to the different rates of the atmospheric deposition
