Abstract
Fragmentation and destruction of the Atlantic Rainforest make its conservation essential. The litter is an important component of this system, and reveals differences in deposition in the different Brazilian ecosystems. This research aims to evaluate the effect of rainfall and air temperature on litterfall input in a forest fragment at the municipality of Sorocaba, São Paulo State, Brazil. The average contribution of litterfall was 6.9±0.4Mg ha-1 yr-1, comprising 65% of leaves. There were differences between the seasons, with the less amount in the dry season. The correlation of litter and its fractions was not relevant for the same month of air temperature and rainfall measurement. However, the correlation is significant when related to the previous month, demonstrating that the response of vegetation to environmental changes is not immediate.
