Abstract

Rural ethnic minority groups in Cat Tien National Park (CTNP) have relied heavily on non-timber forest products (NTFPs) and threatened its natural forest environment. Still, the real context of the NTFP consumption between indigenous peoples (IPs) and migrant ethnic minority group (MEs) has been poorly comprehended. Also, the participatory rural appraisal (PRA) and the “walk-in-the-wood” method were applied to analyse the NTFP consumption between these IPs and these MEs. The study results indicated that the two local groups had a high or a relatively high dependence on the NTFPs and there was a shifting trend from subsistence to cash income (p-value = 0.000 < 0.05). Also, these IPs had a better knowledge about edible forest plants than these MEs, whilst various more MEs consumed forest fauna for medicinal demand. These MEs harvested and consumed those NTFPs more intensively, but these IPs did the resources for more self-consumption related to the indigenous traditions. Based on the local context, NTFP use patterns, cultural dissimilarity, and local capacity empowerment remain needed in park administration strategies. Similarly, culture-based arrangements would contribute to positive outcomes and sustainable management of the park.

Abstract

Javan slow loris (Nycticebus javanicus) is one of the endemic wildlife on Java Island. This species owns particular characteristics, including arboreal, solitary, and nocturnal natures. The species is threatened due to habitat loss and illegal trafficking. Nevertheless, their current geographic distribution remains unclear and environmental factors impact on these species is mostly unknown. This study aims to predict the habitat suitability of javan slow loris in the Conservation Management Forest Unit area of Mount Halimun Salak Forest Group. The study employs a species distribution modeling approach using Maximum Entropy. The presence data of javan slow loris was collected from the radio-telemetry devices used in post-release monitoring. The modeling utilizes elevations, distance from the settlements, slopes, and land covered as its environment variables. The result shows that 52% of the study areas, or 54,669 ha are suitable as the habitat of N. javanicus. Since as the largest protected area on Java Island, Gunung Halimun Salak National Park is one of the natural habitats that are pivotal for this species. This study provides essential documentation for developing management strategies within protected areas. Hence, the result of the study could serve as one of the factors in the determination of animal release location in the future.

Abstract

One environmental service provided by A. crassicarpa plantation is extrafloral nectar which has been widely used for beekeeping since 2019. Nevertheless, nowadays between apiaries practiced unfair competition since there were price fall led by oversupply and low demand after covid pandemic ended. Thus, evaluating the cost structure, profitability, and its feasibility value are critically required. The study's objectives were to 1) evaluate cost structure, revenue and profitability and 2) to conduct a feasibility analysis of each apiary type. This study was conducted from in 2019 to 2022 at the Siak Regency, Riau, Indonesia. Structure interviews combined with desk studies were carried out to collect the data. Data were analyzed based on cost structure, revenue, profitability, and feasibility analysis. All types of apiaries were feasible since they could cover variable and fixed costs. However, it revealed that all types of apiaries experienced minus in profitability in the fourth of financial year. In general, variable cost relatively increased to the level of 50% of total cost in the fourth year. In contrast, fixed cost was relatively declined to less than 50%. Apiaries managed two rits had a better performance in cost structure to face the competitive market followed by apiaries managed three rit. Meanwhile, apiaries managed rit one experienced such a difficult challenge to survive.

Abstract

Shorea leprosula belongs to the Dipterocarpaceae family and grows in Indonesia's tropical forests which have an economic and ecological role. They are a plant in tropical forests that is known as a producer of fruit and tengkawang oil. The presence of S. leprosula trees in the habitat naturally at this time was very hard to find and began to decrease in population. This study aims to determine the potential and distribution pattern of S. leprosula found around KHDTK Aek Nauli. The research method uses the plot path method measuring 20 m × 20 m, the total number of plots is 150 plots. The research results show that the potency of S. leprosula is 63.17 m3 ha-1. The highest important value index of S. leprosula at the tree level was 25.45%. The distribution pattern of S. leprosula at the sapling, pole, and tree levels was clustered, while the distribution pattern at the seedling level was random. The importance of information about the potential and pattern of S. leprosula to be known as an indicator of the current status of its population at KHDTK Aek Nauli and as an information basis for managing management S. leprosula for support preservation in the forest.

Abstract

Conservation partnerships are institutional innovations for self-empowering so that people are no longer dependent on forest areas. Initially, it regulated the relationship between the rights of non-timber forest product collectors (NTFPs) and their obligation to maintain sustainability, such as in the Bukit Barisan Selatan National Park (BBSNP). The high interest in becoming members has not been matched by the optimal implementation of the program that has been implemented since 2018 in the BBSNP traditional zone. Characteristics and perceptions are considered to have an influence on people's behavior in utilizing NTFPs and being interested in becoming members of the partnership. The aim of this research is to analyze the influence of community characteristics and perceptions on the utilization of NTFPs and their desire to become members of the partnership. Data collection used interviews and literature studies, analyzed statistically inferentially in December 2022 by testing the partial least square structural equation modeling (PLS-SEM) hypothesis using the Smart PLS.4.0 software for students with a sample of 62 respondents, namely the partnership permit applicant community. The results of the hypothesis test showed that the characteristics and utilization of NTFPs variables influenced the community's interest in becoming members of the conservation partnership. Perceptions affect the utilization of NTFPs variables. The use of NTFPs acts as a mediator between perceptions and interest in becoming a member. Misperceptions about conservation partnerships affect the implementation of the program. When public perceptions are improved through outreach activities, coaching etc will shape the character of the community to develop livelihoods and productive activities outside the area and stimulate voluntary leaving of the area without social conflict with area managers.

Abstract

The endangered javan gibbon (Hylobates moloch) has been threaten by massive habitat loss and fragmentation in Java. The survival of the second largest population which inhabited unprotected Dieng mountains faced greater risk to habitat conversion and fragmentation. The landscape-level habitat monitoring using spatiotemporal quantification is crucial as a baseline data for javan gibbon conservation. Here, the land-use and land-cover (LULC) change of the Javan gibbon habitat during 1994–2009–2021 and its fragmentation in the Dieng mountains were quantified. This study revealed there were no significant decline in the total of forest. However, its quality was degraded in the interior of forest block. The forest has more fragmented from large patches into smaller patches and increased forest edge. The higher fragmentation happened in the areas that traversed by road. Six suitable forest blocks were identified with varying level of connectivity. Protection and restoration both in the forest and in the interior forest is immediate need, especially in the main forest block. The extra effort is also crucial in the connected forest but traversed by road. The blocks which closely isolated by road could be potentially reconnected by artificial canopy bridge, while the other distantly isolated block might need habitat restoration for corridor.
