Net precipitation in a forest fragment of Mata Atlantica

This study was carried out in the Mata do Paraiso Experimental Training and Educational Station located in Viçosa, Minas Gerais state with the objective of estimating the net precipitation along a segment of a recently regenerated native semideciduous secondary forest, from September 2002 to May 2003. Throughfall and stemflow measurements were registered in three plots. During the study period of 5/9/02 through 7/5/03, 30 rainfall events have been monitored. Results showed values of net precipitation of 849,6 mm, throughfall of 831,7 mm, stemflow of 17,9 mm and loss interception of 189,9 mm corresponding respectively to 81,7%, 80,0%, 1,7% and 18,3% of gross precipitation value which totaled 1039,5 mm for the study period.
