Ecological characteristics of gandaria (Bouea macrophylla Griff) at dungus iwul nature reserve and yan lapa nature reserve Bogor regency

Abstract

Gandaria (Bouea macrophylla Griff) is the identity flora of West Java Province. Naturally, the gandaria habitat in West Java is found only in the Yan Lapa Nature Reserve (CAYL) and Dungus Iwul Nature Reserve (CADI). In the ecosystem of CADI, and CAYL the position of gandaria in the community shows a low level of dominance. The presence of invasive species in CAYL and CADI is feared will threaten the stability of ecosystems in the region in the future including the presence of native flora. This study aims to study the level of tolerance and adaptation of gandaria in nature by knowing the pattern of individual spread in the gandaria population and the type of gandaria association with other species in various environmental. This is interesting to study because of the limited efforts of species conservation and genetic conservation of gandaria, while the condition of the natural population is increasingly threatened. Individual distribution patterns in gandaria populations in CADI and CAYL are random and clustered. Gandaria at Dungus Iwul Nature Reserve and Yan Lapa Nature Reserve are positively associated with iwul, whereas the Hawuan is negatively associated. Gandaria is not associated with asam keranji, manii, kokopian, leungsir, putat, and teureup. However, gandaria is not with menteng monyet dan kitulang in CADI while in CAYL have positive position.
