To evaluate litter production monthly, a experiment was carried in RPPN Fazenda Tamanduá, Santa Terezinha (PB), from august/2005 to july/2006. The litter collectors of 1m x1m were distributed in a well preserved Caatinga forest sister. Litter was fractioned into leaves, stems, reproductive structures and miscellany, and then dried and weighed. Estimated total litter production in the twelve month was 2.283,97 kg ha-1, being 65,09% leaves, 25,41% stems, 8,72% reproductive structures and 0,87% miscellany. The magnitude of litter deposition was leaves > stems > reproductive structures > miscellany, with deposition seasonality, with deposition peacs in the sainy season begin.
