Abstract

Diversity of biological resources in primary forest is not only limited to the woody plant species, but also covered by underground plant which has diverse species high diversity. This underground plant as one part of the forest ecosystem is a plant that has potential as a medicine. The study aims to conduct an inventory of underground plant species in Gunung Gede Pangrango National Park West Java Province. The method for inventory used spasial analysis with land management unit and multi stage sampling. The spasial analysis used three categories, first the zonation map, second the soil characterization map and the third altitude map. The LMU consist of 6 areas with total plot number 60. The results showed there are 83 species underground plant consist of 45 family. The family consist of Acanthaceae, Annonaceae, Apiaceae, Apocynaceae, Araceae, Araliaceae, Aspleniaceae, Asteraceae, Balsaminaceae, Begoniaceae, Compositae, Convolvulaceae, Cucurbitaceae, Cyperaceae, Elaeagnaceae, Equisetaceae, Fabaceae, Gesneriaceae, Gramineae, Hypoxidaceae, Lamiaceae, Malvaceae, Marattiaceae, Melastomataceae, Menispermaceae, Moraceae, Musaceae, Myrsinaceae, Oxalidaceae, Passifloraceae, Piperaceae, Plantaginaceae, Polygalaceae, Primulaceae, Rosaceae, Rubiaceae, Sellagineaeeae, Smilaceae, Solanaceae, Symplocaceae, Urticaceae, Verbenaceae, Woodsiaceae, Zingiberaceae. The underground plant has a potential as medicinal plant.Keywords: Gunung Gede Pangrango National Park, inventory, land management unit, medicinal plant, underground plant

Abstract

Sirami EV, Marsono D, Sadono R, Imron MA. 2018. Ideal planting space for merbau (Intsia bijuga) forest plantations in Papua based on distance-dependent competition. Biodiversitas 19: 2219-2231. Distance-based competition between merbau (Intsia bijuga (Colebr.) Kuntze) and neighboring trees could be applied to determine the planting space between merbau trees and shade trees in plantations. This research was conducted to identify the characteristics of merbau competition with neighboring trees and determine the ideal spacing of merbau trees. The sampling design using was the systematic line technique with hypothetical plot and sample tree as the quadrant center. The competitors were determined using a virtual high approach and header contact. Distance-based competitions were identified using the Hegyi index. Sixteen species had the highest competition index because of their dominance in the tree structure, namely Pometia coriacea, Intsia bijuga, Pimelodendron amboinicum, Horsfieldia laevigata, Palaquium amboinense, Pometia pinnata, Garcinia sp., Spathiostemon javensis, Prunus costata, Sterculia macrophylla, Terminalia complanata, Lepiniopsis ternatensis, Horsfieldia irya, Dysoxylum octandrum, Buchanania arborescens, and Ficus similis. Merbau responded to the high intensity of competition by tilting its canopy in the opposite direction to the position of the competitors’ canopy, making an irregular canopy shape, and growing the first branch at the lowest point on the stem. The ideal planting space for merbau trees in the plantations was 3-7 m.
