Resumo
Litter is the main component that maintains forest productivity through nutrients
cycling. This study had as objective to quantify accumulated litter and its
compartmentalization in four vegetation types: “Strictosensu Savanna”, permanent
preservation area (PPA), Eucalyptus stand and Pinus stand. In each area, 30 (thirty)
samples were randomly collected with a wooden frame (25 cm x 25 cm). Samples
were weighed and then separated in compartments: leaves/needles, branches, bark,
reproductive material and miscellany. The fraction leaves/needles is the one that
contributes the most for litter formation, followed by branches, due to senescence and new leaves formation. Pinus has the highest total amount of litter, because the
stand is old and needles decomposition is slow. Forest formations show the same
litter quantity and compartmentalization pattern.
