One benefit of vegetation is litter produced that play an important role in improving and sustaining the soil quality. In addition, the litter decomposition process also produces nutrients that improve soil fertility and can be used by plants. The purpose of this study was to evaluate the production of litter and the contribution of nutrients from litter of five dominant tree species in the Sub-watershed Tondano, Minahasa, North Sulawesi. The study was conducted in October 2010 - May 2011. Litter production is measured using the net litter container that is placed under the canopy of the five tree species, with each tree 15 observations and repeated three times. Litter collection is done every day. Litter is analyzed in the laboratory of the University of Sam Ratulangi, Manado, to determine content of macronutrients and micronutrients. The results showed that litter in the wet season were produced by Elmerellia celebica that is equal to 16.11 Mg ha-1 year-1. The dominant macronutrients of litter is C. The C content is highest in the litter of Eugenia aromaticum, that is equal to 50.24%. The dominant micronutrients are Fe and Mn. The highest content of Fe and Mn are in litter of Elmerellia celebica, which amounted to 416.4 mg kg-1 and 132.5 mg kg-1, respectively.
