Abstract

Research at the three locations of Altingia excelsa Noronha plantations in Candikuning, Bali has been carried out to examine the changes in vegetation that grows naturally in the low layer after 22 years (1986 -2008). The results showed that 40 species of seedling, and 4 species of shrubs and young trees were found in three plots of the plantation forest. Compared to the results of the previous study, 22 years before the present study (1986), species richness was decreased dramatically accompanied by changes in species composition. Crown cover of herbs group were decreased, but shrubs and young trees were increased except for the plot 1938 due to edge effects. Lightdemanding species were disappeared and replaced by shaded-tolerant species. The primary tree species which are commonly found in the surrounding natural forest and previously found in research plots had been disappeared, and replaced by late secondary tree species, and seedlings of A. excelsa which is actually animmigrant species. Succession under the plantation forest of A. excelsa are generally slow.

Abstract

ABSTRACT Low layer plants as one of component in forest ecosystem today still lack of attention due to the limited information about them. Low layer plants plays an important role in forest ecosystem, and also they are potential to be use as a medicinal plants, genetic resources and other uses that are not yet revealed. For that reason reseach about Low Layer Plants ; Community Structure and Their Use as Medicinal Plants need to be conducted. The objective of this research was to get the information about : (1) Community structure of low layer plants in compartment seven Kaliurang protection forest and (2) Species that are use as a medicinal pants. To fulfill this goal, small plots of 1 x 1 m along forest pathways were made in sampling area. Result showed that as many as 47 species of low layer plants were found in sampling area. There were five main species which has high importance value index : Eupatorium riparium Regel. with importance value index 21,29%, followed by Eleusine indica Gaertn.17,82 % , Oplismenus burmanii Beauv. 14,61 %, Diplazium proliferum 14,04% and Panicum reptans Kunth. 11,27 %. From those 47 species, as many as 10 species are known as a medicinal plants, they are : Melastoma malabathricum L., Physalis angulata Heyne, ex. Wall., Ageratum conyzoides Linn., Elephantopus scaber Linn., Psidium guajava Linn., Justicia gendarussa Linn., Alocasia macrorhiza Schott., Eleusine indica Gaertn., Villebrunea rubescens Bl. and Phyllanthus niruri L.
