Abstract
Indonesia has extensively reforested mangroves to stabilize coastal ecosystems and mitigate climate change. Reforestation’s long-term effects on recovering mangroves are not extensively established because most projects are only observed for two years. It raises the question of whether mangrove replanting aids biodiversity conservation and ecological recovery. This study will characterize Flores Island mangrove ecosystems after ten years of regeneration.
Abstract
Indigofera tinctoria L. is known to produce economically valuable indigo dye. Recently, I. tinctoria has also been considered a potential species for establishing energy plantations because this species can rapidly produce large quantities of biomass. However, knowledge about its fuelwood properties is still limited. To optimize utilization of this biomass material as a source of energy, the fuelwood properties of this species were evaluated. In addition, the
Abstract
To switch the origins of wood resources from natural to planted forests, evaluation of wood from planted trees is essential. The objective of this study is to provide the relevant wood properties promoting the utilization of wood from planted trees in the tropics. Growth characteristics (stem diameter at 1.3 m above the ground and tree height) and stress-wave velocity of stems were measured for two six-year-old red meranti species, Rubroshorea leprosula and
Abstract
Understanding drought propagation is essential for effective water resource management. This study employs an innovative approach to examine the transition from meteorological drought (MD) to hydrological drought (HD) in the Upper Nan Watershed (UNW), Thailand, using the standardized precipitation evapotranspiration index (SPEI) and standardized streamflow index (SSI). Cross-wavelet transform (XWT) and Pearson’s correlation analyses reveal a significant positive
Abstract
This study examines four regression models to estimate tree-level above-ground carbon stock (AGC) in the clonal teak plantations of Wanagama Forest, Indonesia using a data fusion of UAV-LiDAR and RGB aerial imagery. Data collected in the field were diameter at breast height and tree height. Vegetation indices were derived from the visible bands of a georeferenced orthomosaic captured by DJI Mavic 2 Pro. The LiDAR data was obtained using GeoSun GS-100M device
Abstract
Tribal leaders in Papua had been positioned as both cultural symbols and real decision-making leaders, but they have lost their power over natural resource management and forests. Using the case of nutmeg management by the tribal Baham-Matta community, we present changes in the power constellations within the local social structures, in which the Kings (Patuans), the highest tribal leaders, have increasingly been unable to rule their people. In this research,
Abstract
The wide areas of critical land in Indonesia are attracting a high level of attention due to the significant influence of global warming. Addressing this issue requires several priority efforts, such as critical land rehabilitation programs. The level of critical land rehabilitation can be evaluated with remote sensing technology. Therefore, this research aimed to assess critical land in South Sulawesi rehabilitated by PT Vale Indonesia Tbk (PT VI) as compensation
Abstract
Hipposideros spp. are insectivorous bats and karst cave dwellers. This study aimed to study the roosting ecology, reproduction, and population fluctuations of three species H. diadema, H. larvatus, and H. ater in Gunung Sewu Karst region, Indonesia. Age and reproductive status of individuals were identified and analyzed using a combination of forearm length (FA) and body mass grades (W). Multiple regression analysis was used to determine the correlation between
Abstract
Arbuscular mycorrhizal fungi (AMF) diversity is influenced by biotic and abiotic factors. Several studies have shown the presence of AMF in ex-gold mining areas with low soil fertility and heavy metal accumulation. The purpose of this study was to analyze the diversity of AMF species in artisanal gold mining areas. The experimental design used is randomized group design with two treatment factors: the interval distance range from tailings disposal point (A)
Abstract
Ecotourism is a type of forest management that places a strong emphasis on the idea of balancing the use of forest resources for both environmental and economic purposes. Pinus Sari Forest (PSF) is an ecotourism object destination with the main tourist attraction being old pine trees which mark the shift from pine sap harvesting to tourism activities. Due to the transition of forest management in PSF, it is necessary to assess the sustainability of ecotourism
