Abstract. Kasihiw P, Bawole R, Marwa J, Murdjoko A, Wihyawari A, Heipon Y, Cabuy RL, Benu NMH, Hematang F. 2023. Floristic richness and diversity of Bintuni mangrove, Bird's Head Peninsula, West Papua, Indonesia. Biodiversitas 24: 2887-2897. Mangrove ecosystems play an important role in the functions of coastal protection, fish and other living-organism habitats, carbon storage, and the livelihood of local people. Yet, mangrove forests generally face ecological threats like anthropogenic pressures. However, fewer studies were carried out in this area, so this research aimed to reveal the vegetation diversity and richness in Bintuni, not only the true mangroves but also the mangroves associates with three different conditions, namely sandy areas called protection forests, disturbed forests called production forests, and delta called nature reserve. The results showed that species vegetation in the Bintuni Mangrove could be differentiated as true mangroves (29.82%) and mangrove associates (70.18%) of the total species richness of mangrove vegetation where in terms of taxonomic composition, the three forests encompassed 25 families, 47 genera, and 57 species clustered into 9 lifeforms. Then, the vegetation diversity and richness were highest in the nature reserve, and 34 (59.65% of total species number) species of vegetation in common share in three forest types. Consequently, frequent checking of vegetation richness is important since the Bintuni mangrove does not seem to have a significant threat like massive conversion of mangrove.

Abstract. Kasihiw P, Bawole R, Marwa J, Murdjoko A, Wihyawari A, Heipon Y, Cabuy RL, Benu NMH, Hematang F, Leftungun NY. 2024. Mangrove distribution to support biodiversity management in Teluk Bintuni District, West Papua, Indonesia. Biodiversitas 25: 644-653. Mangroves play an important role in coastal ecosystems, but the areas of mangroves are decreasing globally. Understanding the ecological and geographical distribution of mangroves will be useful to develop sustainable management and policy. Thus, this study aimed to analyze the ecological and geographical distribution of mangroves in Teluk Bintuni, West Papua, Indonesia. The distribution of mangroves was investigated to see the relationships between elevation and the number of individual mangroves at the family level. Vegetation data were collected by setting 180 circular plots and geographical data were obtained from secondary sources. Our study revealed that Rhizophoraceae family was found in all plots with 97.78% presence, whereas Acanthaceae and Meliaceae families were found in half of the plots with 65% and 60.56% presence, respectively. Lythraceae, Primulaceae, Malvaceae, and Arecaceae were only found in 15% of the plots. Elevation affected significantly the presence of mangroves which there mainly occurred in elevation between 10-30 m asl, while they were lower in below 10 m asl and above 30 m asl. Species belonging to Acanthaceae and Lythraceae, such as those from the genera of Avicennia and Sonneratia, were found more abundant in the low elevation (seaward zone) than in the higher elevation (landward zone). In contrast, species belonging to Meliaceae and Rhizophoraceae were more abundant in the landward zone with the presence of genera Xylocarpus, Bruguiera, Ceriops, and Rhizophora. The distribution of Arecaceae, Malvaceae, and Primulaceae did not show a significant pattern where they appeared randomly in mangrove forests. Geographically, 12.43% area of Teluk Bintuni District was mangroves which mainly occurred in the eastern and southern parts. Based on forest status, 2.23%, 35.60%, 10.46%, and 51.71% of mangroves in Teluk Bintuni occur in non-forestry use areas (Area Penggunaan Lain/APL), conservation forest (Hutan Konservasi) in the form of nature reserve, protected forest (Hutan Lindung), and production forest (Hutan Produksi), respectively. As the mangrove ecosystem has been part of local people, the specific management to support biodiversity in mangrove forests must be put officially in the development program.

Abstract. Marwa J, Ungirwalu A, Imburi CS, Djitmau DA, Murdjoko A, Benu NMH. 2024. Ecological perspective to sustainably manage the secondary forest in the lowland of Doberai Peninsula, Indonesia. Biodiversitas 25: 2720-2732. This research aims to examine the composition of flora and fauna in secondary forests, with the aim of using the results to provide input for sustainable forest management. Suggestions for proper ecological management have been put forward, as they are crucial for preserving ecosystem functions and protecting species. We revealed that the identified area was a secondary forest with a composition of 225 species and 83 families of vegetation. The distribution was fairly uniform, encompassing 6 life forms: ferns, herbs, lianas, palms, shrubs, and trees. For fauna, the result indicated the presence of 10 species of mammalia, 37 species of aves, 6 species of reptiles, and 4 species of insects. The secondary forest still supports a high species richness of vegetation and fauna. These findings suggest that the secondary forest is undergoing a successional process in which various vegetation, particularly lianas and herbs, compete to gain more sunlight due to increased canopy openness. Forest management must optimize multi-factors, as in this research, and we suggest considering development and conservation, utilization of buffer zones, monitoring vegetation and animal breeding, and reforestation. The balance between development and conservation is critical, offering opportunities for sustainable practices and community involvement.
