See more at litter Examples of leaf litterleaf litter Although nutrient concentrations in leaflitter were higher in the burned plot, the nutrient fluxes were 60-80% lower than in the unburned plot. No seasonal trends were found for the concentrations of nutrients in leaflitter. The weight of the airdried biomass was determined for the fractions grasses, herbs and leaflitter. The number of ant species in the leaflitter decreased exponentially without evidence of a peak in species richness at mid-elevations. However, the study did not include analysis of leachates from leaflitter and direct deposition of invertebrate (and sometimes vertebrate) carcasses and excrement. These surface fires are deceptively unimpressive, creeping along the ground as a thin ribbon of flames burning through the leaflitter. Amount of leaflitter was estimated as the number of leaves pierced by a metal stake thrust into the soil at the site. Despite the fact that there are many potential forest products, only firewood, tree and grass fodder, and leaflitter significantly contribute to the household economy. Further, a large difference in income from different forest products (fuel wood, grass and fodder, and leaflitter) by these income groups is also evident. Buttressed trees were associated with deeper leaflitter accumulation at their bases and higher char heights than trees without buttresses. We used a marked area of 1 m2 on the ground where leaflitter and seeds were cleared. The ground below each plant was cleared of leaflitter and fallen fruits so that fruit fall could be quantified. However, late dry-season fires will encounter higher amounts of leaflitter raising fire probability in forests. Higher soil compaction and less leaflitter in the logged forest, as demonstrated in this study, could have resulted in lower beetle numbers.
