The Dois Irmãos forest is one of the few remaining areas of the Atlantic Forest in the State of Pernambuco. The dams of Meio, Prata and Dois Irmãos, which belong to the Prata Basin, are in it. The objective of this work was to study the rainfall partitioning in a fragment of the Atlantic forest in the Prata basin, in Recife, PE. 24 raingouges were installed in the interior of the forest to measure the throughfall and 20 trees of superior extract and 10 of the sub-forest were selected to determine the stemflow. The results showed values of loss interception of 208,3 mm, net precipitation of 1431,7 mm, throughfall of 1392,4 mm, stemflow by superior stratum of 6,6 mm and stemflow by sub-forest of 32,8 mm, corresponding to 12,7%, 87,3%, 84,9%, 0,4% and 2%, respectively.
