SUMMARY:
The litter is the most superficial layer of the forest floor and, analyzing its deposition is fundamental to evaluate the stability of the forests. The objective of this work was to evaluate the litter input on the edge of three forest fragments with different use histories. The fragments are located in Nisia Floresta FLONA, being classified in F1, F2 and F3. 54 collectors were installed (collector area: 0.159 m²), 18 in each area, spaced from 0 to 100 in relation to the border and, monthly, for 12 months, all the deposited material was collected. The estimated litter deposition was 3,227.90 kg ha-1 year, 3,315.60 kg ha-1 year and 1,775.90 kg ha-1 year, respectively, for fragments F1, F2 and F3, during the one year. collect. The largest contribution in F2 was due to the location of the fragment, which is located in the area of greater floristic diversity of Flona, composed mostly of adult individuals. The litter input had seasonal behavior, presenting greater deposition in the adverse period, indicating that rainfall acts as a regulator of this material. About the contribution of litter from the edge to the interior of the fragments, only in F3 there were statistical differences with values between 93.87 kg ha year and 261.7 kg ha year (100 m). Fragments with high disturbance histories deposit less litter from the edge to the interior of the forest, claiming that this is the most degraded fragment.
