摘要：
The objectives of this study were to evaluate the deposition of litter over two years and the nutritional quality of the litter, depending on the planting space aimed at forest restoration. The planting space 1 x 1, 1.5 x 1.5, 2 x 2 and 3 x 2 m, are the sampling units of the treatments. In 1 x 1 m spacing greater deposition of litter, with no differences between the units other spacings was observed. Leaf fraction showed, in all spacings, greater intake of litter (77%). The higher nutrient content was observed in the 1 x 1 m spacing. In general, was observed the following order as the nutrient content of litter N> Ca> K> Mg> P.
