Floristic Composition of Buah Hitam Habitats in Lowland Tropical Mixed Forest of West Papua, Indonesia

Abstract The biotic factors in tropical lowland forests, especially vegetation, are essential for the sustainable management of forest products. The study aimed to investigate the species richness and diversity of trees in Buah Hitam habitats, and study the tree communities formed by tree species by collecting the data from the habitats of Buah Hitam in Wondama Bay, West Papua, Indonesia viz. primary forest, secondary, and the garden with plots 9, 9, and 8 respectively. The species richness and diversity were higher in the primary forest than that in the secondary and garden. Tree communities indicated that the primary forest differed from the secondary and garden. The habitat types have been shaped as a result of anthropogenic activities for decades. This finding is necessary to set the consensual programs by the government and local people particularly in conservation and sustainable management for the three habitats.

摘要：热带低地森林中的生物因子，尤以植被为重，对林产品的可持续经营至关重要。本研究以印度尼西亚西巴布亚省温达马湾（Wondama Bay）的黑果（Buah Hitam）栖息地为研究区域，旨在调查该区域内树木的物种丰富度与多样性，并通过分别在原生林、次生林与人工园中设置的9个、9个和8个样地采集数据，解析由树木物种构成的群落特征。研究结果显示：原生林的物种丰富度与多样性均高于次生林与人工园；树木群落分析表明，原生林的群落组成与次生林和人工园存在显著差异。上述生境类型均为数十年人类活动干扰塑造而成。本研究结果可为政府与当地民众针对这三类生境制定保护与可持续经营的共识性方案提供科学依据。
