Litter deposition was measured in a 7,455 m² area reforested with tree species over a redyellow "Argisoil" of medium texture during one year. This area is owned by Sítio Laranja Azeda,in the subdivision of Pinhal, in Limeira, SP, located in the peripheral depression of the state (22º33'17" S and 47º24'17" W), at an altitude of 567 m. The local climate is classified by Köppen as Cwa-type, with humid and hot summers and dry and cold winters. Litter average production was estimated monthly by 21 0.25 m² collectors, randomly distributed in each of the different topographic situations. Average litter production of undergrowth in the dry season was 697 kg/ha and 407 kg/ha in the wet season. These are intermediate values between the semi-decidual seasonal forest fragments of São Paulo state and the Floresta da Tijuca (reforested area), areas at more advanced stages of secondary succession; and upper values when compared with other reforested areas in São Paulo. The results allowed to conclude that: a) litter production had a strong seasonal variation, especially a more intense deposition during the dryest months; b) litter productions differ in each topographic situation; c) the undergrowth production is a strong sign of the growth and ecological equilibrium of this new forest.
