Abstract

Rafflesia meijerii was found in 2004 in Batang Gadis National Park. It was a new species of the genus Rafflesia and endemic in North Sumatra. The purpose of this study was to analyze the biotic and physical environmental factors that affect the habitat quality and the individual numbers of of R. meijerii at the research sites. Data were collected by purposive sampling method with a plot size of 0,1 hectare. The collected data such as: total of R. meijerii, total and species of vegetation, and physical environment factors. Fourty three R. meijerii was found at the sites. Fourty three individuals of R. meijerii were found in February 2016. Quercus gameliflora was dominant in tree and sapling with IVI 33,72% and 55,83% and Selaginella wildenovii was dominant in seedling and ground cover species. Sixty three individuals of Tetrastigma papillosum were found. The results of the ecological factor analysis showed that each of ecological factors did not significantly affect the numbers of R. meijerii (sig. 0,1009> 0,05).  Keywords: affect, analyze, conservation, endemic, meijerii

Abstract

Utilization of medicinal plants by Krui People those whose raw materials come from agroforestry “Repong Damar” has long been known and this knowledge has been passed down from generation to generation. Repong Damar is a term for agroforestry in Krui. Research has been conducted in Mei-Juni 2018 with the aim to known the species of plant as utilizing medicinal plants. Data were collected through direct interview with snowball sampling technique and field observations. The results showed that 93 species of plants from 40 families were used as medicine. The highest family is Piperaceae (10%). The most widely used plant parts are 46% of leaves and the type of disease that is often treated as medicinal plants is respiratory tract. Keywords: agroforestry, repong damar, medicinal plants

Abstract

Repeated forest fires highly impact on tree species composition. Forest planning requires information about the current condition of species composition. This paper investigates the current tree composition of natural regeneration after repeated forest fires, regeneration process after repeated fires, and strategy of secondary growth related to ecological restoration issues. Re-observation of the 1.8 hectares permanent plot in Samboja Research Forest was conducted in 2011. All trees with diameters above 10 cm at breast height (DBH) were re-numbered and mapped. Herbarium specimen was collected for species identification. Number of taxon was determined, Important Value Index was calculated, species trait of light response was identified based on the references and dispersion index species was calculated. Results show after twenty eight years initial forest fire, 191 species naturally regenerated in the burnt area. Macaranga gigantea, a light demanding pioneer species of Euphorbiaceae was the most dominant species, followed by Vernonia arborea belonging to Asteraceae. Both, M. gigantea and V. arborea had clumped distribution. Eight species identified survived from repeated fires, are Anthocephalus chinensis, Dipterocarpus cornutus, Diospyros borneensis, Eusideroxylon zwageri, Shorea ovalis, Syzygium borneensis, Pholidocarpus majadum and Vatica umbonata. All surviving species was distributed uniformly in the plot. Dominant pioneer species which has grown after repeated fires indicates that the current condition of burnt forest is in the early succession. Protecting forest, assisting natural regeneration and monitoring dominant species are suggested as activities for the ecological restoration.
