Abstract

Forest ecological study with special attention to leaf and litterfall nutrient status has been conducted in several forest types at Natuna Island, Riau Archipelago. Ten plots have been setup which distributed in several forest type areas. Fresh leaf was collected from some dominant tree within the plots, whereas fallen leaves collected from litter traps.Nutrient content especially for N, P, K and Ca analyzed from all combined species of both fresh and fallen leaves.Results of chemical analyses showed that all fallen leaves mineral element concentration, except for Ca,were lower than that in fresh leaf. Presentage of retranslocation of both nitrogen and phosphorus tended to be similar to some earlier studies in several tropical forests. Nitrogen and phosphorus were suspected to be limiting factors of forest growth in this area.

Abstract

A phytososiological analysis of saplings was made using quadrate method in the six yearsold logged-over forest at Sekundur, North Sumatra. The results showed that within 0.2hectare plot, 123 species belonging to 79 genera and 36 families were recorded. Threecommunity types were recognized, i.e. Agrostistachys longifolia - Teijsmanniodendronsarawakanum, Macaranga hypoleuca - Macaranga pruinosa and Endospermummalaccensis - Macaranga javanica communities. The structure and floristic compositionof each community varies and they were related primarily with the forest distur¬bance.There were found that the number of both species and individuals of sapling decreasedwith increasing of the forest disturbance

Abstract

ABSTRACTVegetation Analysis of Natural Forest in Ternate Island, North Maluku. A vegetation analysisof the Ternate natural forest has been conducted by establishing 9 plots of each 30-m x 30-m.All trees (dbh. e?10 cm) within all plots were measured, their positions were determined, andtheir species were identified. In total there were 68 tree species recorded within plots belongingto 34 families. Trichospermum morotainense was the most common species, followed byAlbizia falcataria, Elmerilla ovata, Cordia mixa, and Macaranga longicaudatum. Almost allof the common species such as A. falcataria, Tristiopsis canarioides, Pometia pinnata, E.ovata and Intsia bijuga were found as emergent or canopy trees. According to the ordination(DCCA) analysis there were at least three tree species associations which were related tohabitat characteristics (conditions). However the population?s dominant species varied amongsites, which might be related to the habitat characteristics and/or effects of human activities inthe past.Keywords: Vegetation, natural forest, Ternate, North Maluku

Abstract

ABSTRACTVegetation Analysis of Lowland Forest in Batanta Island, Raja Ampat, Papua. A vegetationanalysis of Batanta lowland forest has been made by setting up 17 plots of each 30-m x 30-mdistributed in 3 study sites were Yenanas (5 plots), Yensawai (7 plots) and Wailebet (5 plots).All trees (dbh. e?10 cm) within all of 17 plots were measured, and determined their positions,and identify their species. In total there were 171 tree species recorded within plots andbelonging to 108 genera and 40 families. Pometia pinnata was the most common speciesfollowed by Anthocephalus macrophyllus, Pangium edule, Toxotrophis illicifolius, andKoordersiodendron pinnatum. Almost all of common species such as Pometia pinnata,Anthocephalus macrophyllus, Celtis hidebrandii and Intsia bijuga were observed as theemergent and/or canopy trees. According to ordination analysis there were five communitytypes, Aporusa?Pometia, Antocephalus-Toxotrophis, Sterculia-Grewia, Ficus-Antocephalus,and Duabanga-Pterocymbium communities. However floristic compositions varied amongplot sites, which might be a characteristic of vegetation of Papua and the nearby small islands.Keywords: Vegetation, lowland forest, Raja Ampat, PapuaKata kunci: Vegetasi, hutan dataran rendah, Raja ampat, Papua

Abstract

A phytosociological study has been conducted in the south-east slope of Mount Salak, Sukabumi, West Java.Vegetation data were analyzed using 21 plots made of 30 m x 30 m which covered various habitat conditions. Atotal of ninety seven tree species (dbh. â?¥ 10 cm) were recorded belonging to 72 genera and 39 families. The mostdominant families occurred in the study area were Fagaceae, Hammamelidaceae and Euphorbiaceae, followed byTheaceae, Meliaceae and Sapindaceae. The dominance of those families was apparently from the contribution ofthe most dominant species Altingia excelsa and the other species such as the Schima wallichii, Castanopsis javanica,Pometia pinnata, and Lithocarpus korthalsii. Spatial distribution of the vegetation is affected by altitude and/orhabitat slope which develop forest community patterns, such as lowland forest, lower and upper slope forests, aswell as lower and upper mountain forests. The distribution of tree species also follows this pattern, i.e certainspecies only occur on certain (specific) habitat type.Keywords: species ekology, Gunung Halimun-Salak National Park, phytosociology

Abstract

Ecological study has been conducted in the forest area of Natuna Island to reveal the structure and composition oftree species. In the 10 plots of 20 x 40 m each, there were 141 species of trees, with a density of 504 trees / ha and12.35 m2/ha of basal area, which was distributed in three forest types. Myrtaceae was the most common family,followed by Euphorbiaceae and Dipterocarpaceae. On the other hand Arthrophyllum javanicum recorded as themost common species together with Syzygium aemum and Ilex pleiobrachiata. The existence of each of the common speciesvaries in each forest type that shows there was a correlation between the condition of the habitat and the presence ofspecies.Keywords: floristic composition, structure, the Natuna Besar, Riau
