The aim of this paper was to conduct a temporal evaluation of the deposition of litter in a human- disturbed area of caatinga in a process of natural regeneration for 16 years. The study was conducted at the Institute for Agronomical Research - IPA station in Caruaru, state of Pernambuco. Litter was collected monthly throughout the year on a total area of 5.48 m2. The total litter was kg ha yaer-1 9158.93, consisting of 28.90%, 16.82%, 16.95% and 37.33% of leaves, twigs, seeds and miscellaneous, respectively. There were seasonal differences in the deposition of litter, with higher deposition in the dry season. However, there was no monthly variation in the deposition of litter between the months of the season and, and with the exception of the miscellaneous fraction precipitation, it did not maintain connection with the deposition of litter. The paper concluded that after 16 years of regeneration, the area has anthropogenic litter deposition pattern similar to that recorded in other areas of scrub and other factors related to seasonal work, modeling the deposition of litter and influencing the cycling of matter in dry environments.
