Abstract

Bamboo forests serve as valuable assets which assist in developing social forestry programs that benefit local communities. The research investigates how bamboo grows and its economic value through two different planting methods which include monoculture and mixed systems at a Indonesian village forest. Researchers used systematic sampling methods to collect data from 21 plots which included 14 monoculture plots 6 mixed-system plots and 1 shrub plot. The research team focused on gathering data about clump characteristics and culm density and regeneration proportion. The researchers used the Mann–Whitney U test to analyze system differences because the data did not follow normal distribution. The study results show that monoculture bamboo systems produce higher output levels and generate greater financial benefits than mixed systems. The monoculture stands achieved an annual output of 6,374 culms per hectare which results in an estimated economic value of IDR 50,992,000 per hectare every year. The mixed systems produced 5,242 culms per hectare each year whereas the system generated an output of 5,242 culms. The study found that monoculture systems produced more young bamboo regeneration which reached 30.8% compared to mixed systems which generated 27.0% of young bamboo regeneration showing that monoculture systems have better regenerative capabilities.

Abstract. Ramlah S, Santosa Y, Santoso N, Rushayati SB. 2021. The variation of bird diversity in various oil palm land cover in North Mamuju, West Sulawesi, Indonesia. Biodiversitas 22: 3068-3074. The development of oil palm plantations provides various positive impacts. On the other hand, this development is suspected to bring negative impacts on biodiversity, especially reducing bird species diversity. Based on the other research, well-managed oil palm plantations that maintain high conservation value areas have high species diversity. This study aimed to identify bird species diversity in different types of oil palm plantation land covers in North Mamuju. Data observation of bird species was performed using the transect method. There were 4 transects on each land cover. The results of this study showed that the young oil palm area had a high index of diversity and species richness. The high species diversity in the young palm area was caused by habitat variations. There was a water flow that provides more feed sources. The distance between the young oil palm area and secondary forest area affected the number of species, species richness and diversity of bird species. The category of insectivore guild which included aerial insectivores and insectivores was the dominant guild in all types of land cover, both in the number of species and the number of individual abundances.

Abstract. Purnomo DW, Prasetyo LB, Widyatmoko D, Rushayati SB, Supriyatna I, Yani A. 2022. Diversity and carbon sequestration capacity of naturally growth vegetation in ex-nickel mining area in Kolaka, Southeast Sulawesi, Indonesia. Biodiversitas 23: 1433-1442. Efforts to restore forest integrity on ex-mining lands are essential to improve environmental quality and sequester carbon. One such effort is through revegetation of post-mined land including in ex-nickel mining in Southeast Sulawesi. This research analyzes the diversity of naturally regenerating plant species in the ex-nickel mining area in Kolaka, Southeast Sulawesi and determines several local tree species with the potential for carbon sequestration. Vegetation survey was conducted using a systematic nested sampling method at the post-mined site with three vegetation types: secondary forest, shrubs and bushes, and a reference/control site (i.e., natural forest in the nearby Lamedai Nature Reserve). Different types of vegetation were analyzed based on factors using Discriminant Analysis. Vegetation composition was analyzed using the Importance Value Index. Furthermore, biodiversity indicators were analyzed using Shannon-Wiener Diversity Index, Species Evenness Index, and Sorensen Similarity Index. Carbon absorption was measured using the leaf sample method and carbohydrate test. The results showed that the condition of the research site had been disturbed, and the succession process was still ongoing. The species diversity at all plant levels was classified as moderate category and the distribution of the community was unstable. At the tree level, the undisturbed areas had higher diversity. Eradication of Chromolaena odorata was needed to preserve the native vegetation and accelerate forest succession. Tree species recommended for restoring the ex-nickel mining area and carbon sequestration as core plants include Vitex glabrata R.Br., Alstonia macrophylla Wall. ex G.Don, Lithocarpus celebicus (Miq.) Rehder, Callicarpa pentandra Roxb., Dacryodes rugosa (Blume) H.J.Lam, Cananga odorata (Lam.) Hook.f. & Thomson, Glochidion rubrum Blume, Terminalia bellirica (Gaertn.) Roxb., and Psychotria calocarpa Ruiz & Pav., and other pioneer plants of Mallotus paniculatus (Lam.) Müll.Arg., Macaranga peltata (Roxb.) Müll.Arg., and Macaranga hispida (Blume) Müll.Arg.

Abstract

Tahura Pancoran Mas, located in Depok City, West Java Province, is Indonesia's first nature reserve and constitutes a critical area for ecological research. Despite its significant ecological role, detailed data on tree diversity and Leaf Area Index (LAI), which represents canopy density, have not been systematically recorded across its management zones, namely the Protection Zone, Utilization Zone, and Collection Zone. This study aimed to analyze tree diversity and canopy density (LAI) across these three zones. Tree diversity data were collected using a modified transect line method consisting of nine plots, each measuring 20 × 20 meters. Canopy structure was recorded using digital hemispherical photography, tree species diversity was measured using the Shannon-Wiener index (H'), and LAI values were processed using the Hemiview software. A total of 81 individual trees were recorded, representing 20 species belonging to 13 families. Dominant species were identified in each zone: Artocarpus elasticus Reinw. ex Blume in the Protection Zone, Arenga pinnata (Wurmb) Merr. in the Utilization Zone, and Sandoricum koetjape (Burm.f.) Merr. in the Collection Zone. Biodiversity evaluation revealed that the mean Shannon-Wiener index across all three zones fell within the moderate category (Protection Zone H' = 2.20; Utilization Zone H' = 1.75; Collection Zone H' = 2.35). LAI results indicated that canopy density was classified as very dense, with values of 2.89, 2.92, and 2.84 in the protection, utilization, and collection zones, respectively. These findings may serve as a scientific reference for developing sustainable management strategies for the Tahura Pancoran Mas area, including planting native tree species appropriate to the ecological conditions of the Utilization Zone, environmental education programs, and periodic vegetation monitoring.
