Abstract

Host trees are vital for the survival of epiphytic orchids, providing necessary light and air circulation for optimal growth. Large trees with tall canopies contribute to the broader distribution of epiphytic orchids in forest areas. This research aimed to identify the characteristics of orchid host tree species in Lore Lindu National Park, considering both elevation zones and orchid growth zones. The research was conducted at various locations within the park, employing the field exploration survey method (cruise method). This method involved comprehensive exploration at each research site and establishing observation paths along pioneer lines, mainly where orchid host trees were found. The findings indicate the presence of 20 types of orchid host trees and 35 species of epiphytic orchids. The basal branching zone (Zone 3) was the most populated by epiphytic orchids on host trees, and the lowland forest was the elevation zone where most orchid host trees were found in Lore Lindu National Park, Central Sulawesi. Keywords: host trees, Lore Lindu National Park, orchids, zone distribution

Abstract

Perception is an essential factor influencing attitudes and behavior toward the forestry partnership program. Apart from that, a person’s perception can positively or negatively impact the program. The forestry partnerships program is a policy that is the basis of a community empowerment program that provides legal access for local communities to meet the needs of non-timber forest products originating from the Bukit Barisan Selatan National Park (BBSNP) area. The research was conducted to identify the role of partnership members’ perceptions as a mediating variable in achieving goals and obtaining benefits as partnership members in the Semaka Region I National Park Management Sector, BBSNP. Data was collected using a questionnaire, and hypothesis testing was performed using Partial Least Square-Structural Equation Model statistical analysis using SmartPLS 4.0 software. The results showed that perception does not play a mediating variable in achieving goals and obtaining benefits as a member of the partnership. The community benefits from the forestry partnership program if they become members even without having a positive perception of the program. Thus, it is possible that they will not commit properly because the important thing is that they have become members because it will be secure and no longer be considered as an encroachment. This means that it is legal access that makes people want to become members of the partnership. So, to increase positive perceptions and ensure the program’s goal is achieved, namely preserving forests and ensuring the fulfillment of people’s lives, it is necessary to increase the intensity of activities that influence people’s perceptions, for example, socialization, mentoring, and coaching.

Abstract

This study systematically assessed tree species composition and regeneration status within two protected national parks in Bangladesh: Singra National Park and Ramsagar National Park. We employed a stratified random quadrat method across 100 sample plots (50 quadrats from each national park of 10 m x 10 m). Our findings revealed 45 tree species belonging to 25 families. Myrtaceae and Dipterocarpaceae were the most dominant family, having a maximum number of species. We identified 16 exotic species of 10 families and 29 native species of 19 families. Phytosociological parameters like density, frequency, abundance, and importance value index (IVI) were determined. Shorea robusta with an IVI of 47.38 dominated Singra National Park, while Eucalyptus camaldulensis with an IVI of 22.67 was most important in Ramsagar National Park. Regeneration status was good for 15.56% of species, fair for 24.44%, poor for 28.89%, and absent for 17.78%. This study implied the need for collaborative conservation strategies involving policymakers, conservationists, and local communities to ensure the parks’ sustainable eco-custodianship. Keywords: biodiversity, conservation, forest, national park, regeneration

Abstract

Forest carbon dynamic modeling for estimating the carbon stock in short rotation coppice bioenergy plantation in Hungary will be vital for better comprehending the role of black locust (Robinia pseudoacacia) and poplar (Populus sp.) in carbon dioxide sequestration from the atmosphere. The research aims were to estimate the potential carbon stock and describe the carbon distribution of the short rotation coppice bioenergy plantation above and below ground. Various sources were used to acquire parameterization data for developing forest carbon dynamic models. CO2FIX modeling V.3.2 was utilized in the data analysis to estimate the total carbon stock in biomass, soil, harvested wood products, and bioenergy compartments. Modeling has been around for 45 years. In this research, the total carbon stock of black locust and poplar at the end of the simulation period was 64.13 and 131.08 MgC.ha-1, respectively. The average carbon allocation above and below ground for black locust and poplar was 0.76, 19.76, 1.80, and 21.67 MgC.ha-1, respectively. In conclusion, poplar outperformed black locust regarding carbon storage in the short rotation coppice bioenergy plantation. Below ground carbon allocation was much higher than above ground. Therefore, more attention should be paid on below ground allocation through environmentally friendly soil management. Keywords: bioenergy plantation, carbon dynamics, climate change mitigation, CO2FIX model, fast growing species

Abstract

Identification of wood species that are difficult to distinguish from their anatomical structure can be done through phytochemical (extractive substance) profiling. This research aimed to analyze the phytochemical profile as a sorter for three species of mangrove wood from Indramayu and Cilacap Regencies, Indonesia, using the liquid chromatography-mass spectrum. The phytochemical markers of taxonomic were the dominant compounds only found in one wood species. The results showed that the three types of wood are dominated by phytochemicals dissolved in ethanol. The results of LCMS analysis of the ethanol extract showed that the phytochemical markers were triterpenoid, flavonoid, and fatty acyls glycoside groups for Rhizophora apiculata, steroid and naphthalene groups for Bruguiera gymnorhiza, and alkaloid as well as fatty amide group for Bruguiera cylindrica. The dominant compounds that characterize these can be used in sorting between mangrove wood species. Keywords: characterizer, compound, mangrove, phytochemicals

Abstract

Magnetic wood with good electromagnetic wave absorption properties was prepared by comparing synthetic and commercial nano-magnetite (Fe3O4-NP) as sengon (Falcataria moluccana) wood impregnation solution. The co-precipitation method produced a synthetic nano-magnetite with NH4OH as a weak base precursor. Meanwhile, the commercial one was purchased from a supplier. Three levels of nano-magnetite concentration (1%, 2.5%, and 5%) were dispersed in deionized water. The impregnation process was done by applying a vacuum of 0.5 bar for 120 minutes, followed by a pressure of 1 bar for 120 minutes. The results showed that the commercial nano-magnetite caused more improvements in weight percent gain, density, and hardness than the synthetic nano-magnetic, although they were insignificantly different. There was also a reduction in brightness with the overall color change being categorized into other colors because the color became darker with increasing nano-magnetite concentration in both woods. The absorbance capacity of the synthetic nano-magnetite-treated wood was larger than the commercial nano-magnetite-treated wood. This synthetic nano-magnetite-treated wood had been optimally treated at a 5% concentration, making it suitable for use as electromagnetic wave shielding material because it can absorb almost 100% electromagnetic waves. Keywords: Fe3O4, impregnation, nano-magnetite, sengon wood, shielding materials

Abstract

Litter traits and site conditions alter nutrient inputs from deciduous and evergreen forests by influencing litter decomposition processes. Here, we investigated the leaf and stem mass loss rate (MLR) of a deciduous (Tectona philippinensis) and an evergreen (Parashorea malaanonan) tree species and the factors influencing it through an intersite experiment and litterbag method in secondary forests in Lobo, Batangas and Mount Makiling Forest Reserve (MMFR). Variations in initial litter quality (leaf area, specific leaf area (SLA), leaf thickness, vein density), and site factors (light intensity and temperature) were assessed. P. malaanonan has a lower SLA and vein density than T. philippinensis. The leaf and stem MLR were significantly higher in the mixed litter (44.09–57.83%) than that of a single-species litter of either T. philippinensis (28.16–41.83%) or P. malaanonan (33.60–47.66%). The leaf MLR of T. philippinensis was greater when placed in Lobo (where the litter originated) than at a different site (i.e., MMFR). Moreover, leaf litter decomposition was faster in T. philippinensis than in P. malaanonan, particularly during the rainy season. Overall, the study showed that litter decomposition in deciduous and evergreen differed across sites due to variations in litter quality and environmental variables. Keywords: decomposability traits, home-field advantage (HFA), intersite experiment, litter quality, mass loss rate

Abstract

Amphibian is a vertebrate animal whose life is always associated with water. Anura ordo has the most extensive spread in Indonesia. A study on amphibians in Way Kambas National Park has never been conducted. Therefore, the purpose of this research was to find out the diversity, evenness, dominance, temperature, and humidity of three various habitats of amphibians of Anura ordo in Rawa Bunder National Park Management Resort (RPTN Rawa Bunder), Way Kambas National Park, Indonesia. Amphibian data was collected using the visual encounter survey and line transect methods. The results of this research discovered amphibians in 6 families, which consisted of 13 species of amphibians based on observations in three different habitat types. The Shannon-Wiener diversity index (H') was categorized as moderate with the H' of 1.91–2.27. The evenness index (E) was considered stable, ranging between 0.87–0.91. The dominant index (D) falls into the low dominance group, with the D value ranging between 0.13–0.19. This shows that no dominant species is present. Keywords: Anura, amphibians, biodiversity, predominance, Way Kambas National Park

Abstract

The diverse forests in Indonesia require proper management to preserve their delicate ecosystems. Limited production forests (HPT) are prone to damage and require careful rehabilitation to restore them to their original state. Native tree species such as Shorea leprosula are essential for the success of land and forest rehabilitation in HPT areas. This study aimed to assess the potential of S. leprosula species for HPT rehabilitation by examining its growth in the Gunung Dahu Research Forest (GDRF) by measuring the percentage of live plants, tree growth, and soil improvements under S. leprosula stand in sloping land. The results showed that S. leprosula had fast (1.25 cm/year) to very fast (1.79 cm/year) diameter growth, a dense canopy cover with a leaf area index of 2.88, and improved soil physical (soil moisture of 55.54%, topsoil thickness of 6.2 cm, and litter thickness of 16 cm) and chemical properties (pH of 5.2, soil organic carbon of 3.85, total nitrogen of 0.3, carbon-to-nitrogen ratio of 12.8, available phosphorus of 35.3, and exchangeable potassium of 0.76). Therefore, the successful rehabilitation of S. leprosula in GDRF indicates that it can potentially rehabilitate other HPT areas with similar environmental and site conditions.

Abstract

Deforestation on peatlands in Indonesia has become an important issue. To restore the peatland condition, planting native tree species such as mersawa (Anisoptera marginata) is required. One of the problems with planting is the frequent occurrence of inundation at planting sites. The study aimed to analyze the inundation height, which accelerated the height increase of mersawa seedlings in acid or neutral water conditions. The method used was experimental research with a factorial completely randomized design. Factors studied were inundation height, consisting of without inundation, inundation at polybag height, inundation between the tips of the polybags and the apices of the plants, and inundation reaching the apices of the plants. The water composition consisted of peat swamp water, peat swamp water mixed with boiler ash from palm oil mill, and peat swamp water mixed with dolomite lime. The treatment of inundation between the tips of the polybags and the apices of the plants led to the highest height growth, while the lowest were the seedlings without inundation. The interaction between the inundation height and the water composition had a survival percentage of 100%, while the seedlings inundated up to the seedling apices with water treatments had a survival rate of 16%. Keywords: Anisoptera marginata, inundation, peat swamp water, seedling growth
