Abstract

The research objective is to classify the variety of vegetation types at Mount Endut, Gunung Halimun-Salak National Park. Vegetation sampling was carried out with systematic sampling with random start. Vegetation type at alliance level was determined with vegetation ordination using factor analysis. Four vegetation alliances can be extracted from the ordination. These alliances are Castanopsis acuminatissima-Schima wallichii/Freycinetia javanica (alliance 1); Castanopsis argentea-Dendrocnide stimulans/Schismatoglottis calyptrata (alliance 2); Coffea canephora var. robusta-Quercus lineata/F. javanica( alliance 3) and Paraserianthes falcataria-Coffea canephora var. robusta/Oplismenus compositus (alliance 4). Vegetation alliances form due to their similarity in structure, composition, and physiognomy of vegetation. There are four vegetation associations at alliance 1, i.e. Castanopsis acuminatissima vegetation association, Schima wallichii vegetation association, Garcinia rostrata vegetation association, and Quercus lineata- Eurya acuminata /Freycinetia javanica vegetation association. Alliance 2 has four vegetation associations i.e.Dendrocnide stimulans vegetation association, Coffea canephora var. robusta vegetation association, Castanopsis argentea -Castanopsis acuminatissima vegetation association, and Schismatoglottis calyptrata-Etlingera coccinea vegetation association.There are seven vegetation associations belonging to alliance 3 i.e. Castanopsis acuminatissima vegetation association, Coffea canephora var. robusta vegetation association, Quercus lineata vegetation association, Garcinia rostrata-Schima wallichii vegetation association, Euodia latifolia - Pternandra azurea/Schismatoglottis calyptrata vegetation association, Raphidophora foraminifera vegetation association, and Freycinetia javanica vegetation association. Alliance 4 has five vegetation associations i.e Paraserianthes falcataria vegetation association, Coffea canephora var. robusta vegetation association, Maesopsis eminii/ Erechtites valerianifolia - Clidemia hirta vegetation association, Oplismenus compositus vegetation association, and Clibadium surinamense vegetation association.

Abstract

Gewang or Corypha utan Lamk. is tree that support the daily need in Usapisonbai village, Nekamese District, Kupang, Nusa Tenggara Timur The nutrient content of the tree is important to be observed, since the tree is crucial to be sustainable.Three permanent plots were established and random sampling was conducted. The results showed that characteristics of soil are clay in texture, somewhat alkaline, mid in C/N ratio, and high CEC (cation exchange capacity) for calcium, magnesium dan potassium.Nutrient contents of soil were 0.15, 0.002, 0.04, 1.16 and 0.04%, respectively, for N, P, K, Ca and Mg. Litter contribution was dominated by leaves (7.73 t ha-), and other parts reached 6.7 t ha , with their nutrient content of N (0.72), P (0.09), K (0.18),Ca (2.S4) and Mg (0.27%). The significant, differences of nitrogen between nutrient contents and between total nutrient contents through litters (P < 0.05) were found. The nutrient contents of tree are 0.57 N, 0.4, P, 0.75 K, 0.77 Ca and 0.18% Mg. The increase of the tree nutrient could be done by utilizing organic matter or by planting tree species that can increase soil fertility and survive in savanna.

Abstract

Pangi (Pangium edule Reinw.) is one of the Indonesian plant, which is recently becoming rare, especially in Java and Sumatera. Based on the herbarium collections, the plant is distributed throughout Indonesia. It grows well below 300 m above sea level, but it is found up to 1000 m a.s.l., in primary and secondary rain forests, also a long river banks, in teak forests, on dryland, stony or clay soils. Pangi is known as a poisonous tree, but the seeds have been extensively utilized for many favorite dishes. The fresh leaves or seeds or the oil are used as an anticeptic, disinfectant or antiparasitic, to preserve meat and to kill fish, etc. The seeds seem to be dispersed by water, because they have excellent floating capacity. However, in Bacan Island, North Maluku, they might also be dispersed by black monkeys.

Abstract

The species richness and abundance of vascular epiphytes in the lowland dipterocarp forest, East Kalimantan is described. Fifty six species of vascular epiphytes have been recorded within a 6 ha plot, comprising 39 genera and 12 families. It was recorded that 387 trees (9.84%) of the total trees of 3933, have supported epiphytes. The epiphytic plant communities within two different habitat showed that the swamp area is poorer than the dry land habitat, both in species richness and abundance. Asplenium nidu and Pandanus epiplyhcus were recorded as the common species in both habitats;while Platyceriunl coronarium tends to occur at crown layer especially in the dry-land habitat.
