Abstract

An analysis of the composition and structure of lowland natural forests was carried out in Bodogol, Gunung Gede Pangrango National Park (GGPNP). The two study plots (P1CS and P2CS) were located on Cisuren and one plot (P3CP) on Cipadaranten hill. We recorded 107 species and 48 families with an average basal area of 19.73 m2/ha, and an average density of 348 trees/ha. The species richness was poorer than those of the typical lowland rainforests of Kalimantan and Sumatra but comparable to those of the montane forests of Java. The IUCN-Red Listed species were Castanopsis argentea and Castanopsis tungurrut (critical) and Saurauia bracteosa (vulnerable). Based on the two dominant species, the forests can be designated as the Maesopsis eminii-Syzygium acuminatissimum association and Syzygium acuminatissimum-Lithocarpus korthalsii association. Maesopsis eminii was dominant in P1CS (IV= 56.46%) and P3CP (IV=55.94%), while Syzygium acuminatissimum in P2CS (IV= 43.67%). Maesopsis eminii was a strongly aggressive and invasive species, that endangered the purity of the natural forest GGPNP, therefore, it must be eradicated. Vertically, P2CS and P3CP consisted of four strata, while P1CS had three strata. This one-hectare study can be considered as a minimal area to reflect the floristic representation of lowland forest and submontane forest.

Abstract

Kerangas (heath) forest, that forms islands within the lowland dipterocarp forest, occurred at Sebulu, East Kalimantan. Part of the two of the islands and the transition area between them were investigated. Phytosociologically three communities could be identified, i.e. the Cratoxylum glaucum-Dactylocladus stenostachys, Eugenia palembanica-Ilex hypoglauca, and Shorea ovalis-Eugenia acuminatissima communities. They occurred on sandstone flat, sandstone slope and swampy depression respectively. Only Cratoxylum glaucum-Dactylocladus stenostachys community can be considered kerangas forest proper, whereas the Eugenia palembanica-Ilex hypoglauca community the transition and the Shorea ovalis-Eugenia acuminatissima community a variant of the lowland dipterocarp forest. The soils under these communities were peaty, very acid and low in nutrient contents. The economic value of kerangas forest in terms of timber is very low, hence, it would be better to preserve all kerangas forest as conservation areas and utilize them for research, educational and recreational purposes.

Abstract

Chydenanthus is accepted as a monotypic genus and its type species C. excelsus (Bl.) Miers is redescribed. C. dentato-serratus R. Knuth belongs to Barringtonia and is thus excluded from the genus.

Abstract

In my article on the genus ChydenmUhus Miers in Reinwardtia 10 (1) : 28, 1982, I stated that "the genus, like Barringtouia and Abdid-majidia, has one- seeded fruit". This statement is partially wrong. Abdulmajidla fruit has 2-5 seeds, the main reason that the genus was established (Kochumen in Hit.

Abstract

KARTAWINATA, KUSWATA; SAMSOEDIN, ISMAYADI; HERIYANTO, M. AND AFRIASTINI, J. J. 2004. A tree species inventory in a one-hectare plot at the Batang Gadis National Park, North Sumatra, Indonesia. Reinwardtia 12 (2): 145 – 157. The results of the inventory of trees with DBH = 10 cm shows that 184 species in 41 families, represented by 583 individuals with the total basal areas of 40.56 m² occurred in the one-hectare plot sampled. Together with the saplings and shrubs the number of species was 240 belonging to 47 families. The forest is richer in tree species than other lowland forests in North Sumatra, but poorer than those in Borneo and the Malay Peninsula. Dipterocarps constituted 18.42 % of total species with basal area of 18.99 m² or 46.82 % of the total basal area in the plot. The most prominent species was Shorea gibbosa. Hopea nigra, reported to be rare in Bangka and Belitung, occurred here as one of the ten leading species. The species-area curve shows that a considerable number of additional species was encountered more or less steadily up to one hectare and there was no indication of levelling off. A simulated profile diagram shows the forest may be stratified into five layers: (1) emergent layer, (2) upper canopy, (3) middle canopy, (4) lower canopy and (5) ground canopy. Dipterocarps were leading species in the emergent layer, upper canopy and middle canopy. Only 82 species were regenerating as represented by their presence in the sapling stage ranging from 5 to 50 plants/hectare. Macaranga lowii King ex Hook. f. dominated the section which seemed to be previously occupied by gaps.

SADILI, A., KARTAWINATA, K., KARTONEGORO, A., SOEDJITO, H. & SUMADIJAYA, A. 2009. Structure and composition of subalpine summit habitats on Mt. Gede-Pangrango complex, Cibodas Biosphere Reserve, West Java, Indonesia. Reinwardtia 12 (5): 391–404. We undertook a phytosociological analysis of the subalpine herbaceous and shrubby vegetation at the Mandalawangi and Suryakencana meadows and the scrub at the Crater Side at the tops of Mt. Gede and Mt. Pangrango in the Cibodas Biosphere Reserve. We recorded 30 species of 18 families of saplings, shrubs, seedlings and herbs in 78 quadrats with a total area of 7,800 m2. Anaphalis javanica, a woody tall herb and long-lived pioneer was the dominant species in the sapling and shrub stratum, while Isachne pangerangensis, Tripogon exiguus and Carex verticillata were prevalent in the seedling and herb stratum at Mandalawangi and Suryakencana. Stunted shrub is Vaccinium varingaeifolium, dominant in the Crater Side scrub. Based on the importance values, the Mandalawangi meadow may be designated as the Anaphalis javanica-Isachne pangerangensis community type, the Suryakencana meadow as Anaphalis javanica-Tripogon exiguus community type and the Crater Side scrub as Vaccinium varingiaefolium-Seliguea feei community type. The similarity indices between Mandalawangi and Suryakencana community types were very high (>75 %) while those between the Crater Side and Mandalawangi and the Crater Side and Suryakencana were very low (

Abstract

An analysis of the structure and floristic composition of trees with diameters at breast height ? 10 cm in a one- hectare plot in a lowland natural forest at the elevation of 800 m at Bodogol, the Gunung Gede Pangrango National Park, Cibodas Biosphere Reserve, recorded 70 spesies and 30 families with a density of 350 trees/hectare and a total basal area of 23.36 m2. As high as 37 tree spesies (52.86 %) were not recorded in the flora of Mt.Gede Pangrango; they were species of upper lowland forest and dominated the plot. Among 10 main species, only Altingia excelsa and Ficus ribes are montane forest species. Thus the forest plot represents a transition between lowland forest and lower montane forest, which may be called an upper lowland forest. This is a new phenomenon which has not been recorded previ- ously at the Gunung Gede Pangrango National Park. The most prominent species with Importance Value (VI) > 10 % are Schima wallichii, Pternandra caerulescens, Neesia altissima, Luvunga sarmentosa and Maesopsis eminii; the latter is an exotic species invading the natural forest. Dipterocarpus hasseltii is present in the area.

Abstract

The leaf epidermis and mesophyll of fifteen species of Pandanus from Java were investigated to assess the value of anatomical features in species identification and classification. Characters of diagnostic importance are epidermal cell shape, differentiation of the abaxial epidermis into costa and intercosta, adaxial anticlinal cell wall outline, occurrence of raphides in the mesophyll, distribution of cubical crystals, pallisade cell shape, papillae on epidermal cells, and the stomatal complex. Leaf epidermal anatomy was found to be useful in the identification at species level.

Abstract

Since a large number of characters are now known for Freycinetia Gaudich. and Pandanus Parkinson species, it appears useful to consider their use in identifying plants from Java. Fieldwork carried out for this study has provided stronger foundation for understanding morphological variation within the species. This study was undertaken to have a better understanding on the morphology of the family in order to make a better species delimitation. Characters of habit, stem, leaves, auricles, bracts, peduncle and pedicel, inflorescence, staminate flowers (male), pistillate flowers (female), cephalia and berries were found useful in delimitation and identification of Javanese Freycinetia, while characters of habit, stem, prop root, marginal spine, leaves, bracts, inflorescentia, peduncle, staminate flowers (male), pistillate flowers (female), cephalia, drupes were found to be useful for distinguishing among species of Javanese Pandanus.
