Daftar Isi:
- The development of monitoring plots on flora biodiversity has begun in 2008 in order to support the policy of ecosystem-based forest management. These monitoring plots are not only placed on natural forest, but also forests in conservation area, particularly on national parks with lowland forests and mangrove forests as priorities. This study was conducted to identify the composition, density, frequency and dominance of vegetation species, also species diversity and community patterns of flora in biodiversity monitoring plots in Gunung Meja Tourism Park (TP). The research was conducted at 50 ha of biodiversity monitoring plots of Balai Penelitian Kehutanan (Forestry Research Institute) Manokwari, located at the forest area of Gunung Meja TP. The study area was divided into 14 releves. It employed descriptive method with survey techniques and observation. Data was analyzed by tabulation to calculate the Importance Value Index (INP) and the Species Diversity Index (H), while the statistical analysis of ordination was applied to predict the community pattern. The results showed that forest vegetation on biodiversity monitoring plot has a population of 6,777 trees consisting of 2,015 trees of seedling, 492 trees of sapling, 1,791 trees of pole, and 1,479 trees of tree. The total number of woody plant species for all growth stages was 256 species comprising 149 genera and 50 families. They were 150 species (96 genera of 42 families) of seedlings, 173 species (119 genera of 48 families) of saplings, 190 species (116 genera of 42 families) of poles, and 175 species (110 genera of 40 families) of trees. The dominant species of seedling stage was Pometia coreacea (244.98), sapling stage was Aglaia odorata (125.98), pole stage was Medusanthera laxiflora (381.87) and tree stage was Pometia coreacea (489.5). The community pattern of vegetation clustering showed that vegetation on seedling, sapling, pole and tree stages in the observation area was merely a single community group. This condition occurred due to the gradual changes that the presence of species in seedling, sapling, pole and tree stages was unequal resulting in unclear clustering. The Species Diversity Index of seedling level ranged between 2.93 and3.62, sapling 3.23 and 3.96, pole 3.12 and 3.95, and trees 2.95 and 3.95. The process of community succession and stability on the pole and tree levels might occur better and more stable. Regarding the utilization of forest resources, the population around Gunung Meja TP did not even consider its existence and the forest damage, gradually but surely, has occurred. As a matter of fact, such condition might not occur and forest sustainability of Gunung Meja TP can be maintained properly for long-term benefits if the integrated management of the area, the so-called Ecosystem-Based Management, involves all stakeholders.
