The Vegetation Analysis of Natural Habitat of Wild Nutmeg (Myristica Spp) in Halmahera Forest, North Maluku

The vegetation analysis of wild nutmeg (Myristica spp) in natural habitats reveals the composition and structure of vegetation populations in an ecosystem unity. This study can be used to consider the conservation and management of germplasm of wild nutmeg in the forests of Halmahera Island, North Maluku. The research objective was to determine the vegetation composition and structure of the wild nutmeg habitats. We used the point method with a plotless sampling technique to record the species at specific points along a transect. The results revealed that naturally Myristica spp could grow and develop under large basal areas from the vegetation types, e.g. Ficus benyamina, Vatica Papuana, Paraserianthes falcataria, Vitex cofassus, and Mimusops elengi. Pometia pinnata and Duabanga moluccana can affect environmental factors in the natural habitat of wild nutmeg. Myristica spp, Euterpe edulis, and Macaranga sp are vegetation types in natural habitats of wild nutmeg with high dominance and important value index (IVI). Euterpe edulis can be used as an indicator of the uniqueness of the natural habitat of wild nutmeg. At the same time, Macaranga sp indicates that there has been a change in the ecosystem of the natural habitat of wild nutmeg. The natural habitat of wild nutmeg is classified as having a stable ecosystem with minimum disturbance, moderately abundant, and high vegetation species richness.
