“…This indicates that kebun campuran had an important role in biodiversity conservation in human-dominated landscapes. Previous study conducted in the upper Citarum watershed concluded that bird diversity in agroforestry vegetation was influenced more by the complexity of canopy cover and the heterogeneity of landscape than by the diversity of plant species (Parikesit et al 2012). Similar observation was also recorded in kebun campuran in the karst ecosystem of the Pangandaran.…”

“…Additionally, the role of agroforestry in overcoming land-hunger problems, as well as its role in overcoming land degradation (Cooper et al 1996;Mwase et al 2015) and water shortage (Ong et al 2006) due to over-exploitation, has been recognized as very effective. Similarly, the role of agroforestry in biodiversity conservation has been established in various studies (Parikesit et al 2012). It is not surprising, therefore, that the practice of agroforestry is still recognized as an effective way of dealing with environmental crises impacting the social life and ecological conditions of people living in rural areas.…”

Abstract. Parikesit, Withaningsih S, Rozi F. 2021. Socio-ecological dimensions of agroforestry called kebun campuran in tropical karst ecosystem of West Java, Indonesia. Biodiversitas 22: 122-131. Traditional and modernized systems combining agricultural and forestry production systems-called agroforestry-was developed by humans under the influence of biophysical and social conditions which often result in heterogeneous landscape. The so-called kebun campuran (mixed gardens) is one of the agroforestry forms that can be encountered in the humid tropics of Indonesia. However, socio-ecological information of this man-made vegetation and its multidimensional functions in particular environmental settings like karst is still limited. This paper aims to elucidate socio-ecological dimensions of kebun campuran in karst ecosystem in Pangandaran District, West Java, Indonesia. A vegetation survey was carried out to reveal the bio-ecological dimensions of kebun campuran complemented with socio-economic questionnaires. The results show that kebun campuran played an important role for the owners as the majority of them gained economic benefits from this agroforest. More than 50% of the owners had their main income from kebun campuran, therefore, kebun campuran was considered a valuable family asset. Kebun campuran ownership put the owner in a higher social status, despite the fact that 80.9% of them had only elementary education background. Correlation analysis showed that there was a very significant correlation between the areas of kebun campuran, rice-field, and homegarden ownership. The analysis also indicated that the economic value of kebun campuran derived from its products increased as its area became larger. There were diverse products like timber, fruits, fuelwood and forages extracted from kebun campuran. Among economically important species were Albizia chinensis (silk tree), Cocos nucifera (coconuts), Manilkara zapota (sapodilla), Musa paradisiaca (banana). Despite its beneficial value, kebun campuran was not intensively managed. On the other hand, the structural vegetation pattern of kebun campuran was the result of various practices carried out by the owners through the processes of introduction, domestication, and selection of plant species. Maintaining kebun campuran in the coastal landscape of Pangandaran might ensure the future of karst ecosystem in this southern coastal area of West Java.

“…Despite representing the largest reservoir of biodiversity with a rich diversity of flora (>200 plant species/hectare) [4,5] and fauna (>50% of the world's animal species) [6] and its various functionalities, most tropical rainforests, including those situated in Indonesia, are lost or degraded through human intervention over time. Biological diversity in Indonesia is the second greatest globally, and Indonesia has the third-largest area of tropical rainforest [7], with a span of 94.1 million ha of forest in 2019 [8]. Nineteen types of natural ecosystems occur here, from lowland rainforest to alpine, and from marine coastal to deep-sea ecosystems [9].…”

Biodiversity monitoring is crucial in tackling defaunation in the Anthropocene, particularly in tropical ecosystems. However, field surveys are often limited by habitat complexity, logistical constraints, financing and detectability. Hence, leveraging drones technology for species monitoring is required to overcome the caveats of conventional surveys. We investigated prospective methods for wildlife monitoring using drones in four ecosystems. We surveyed waterbird populations in Pulau Rambut, a community of ungulates in Baluran and endemic non-human primates in Gunung Halimun-Salak, Indonesia in 2021 using a DJI Matrice 300 RTK and DJI Mavic 2 Enterprise Dual with additional thermal sensors. We then, consecutively, implemented two survey methods at three sites to compare the efficacy of drones against traditional ground survey methods for each species. The results show that drone surveys provide advantages over ground surveys, including precise size estimation, less disturbance and broader area coverage. Moreover, heat signatures helped to detect species which were not easily spotted in the radiometric imagery, while the detailed radiometric imagery allowed for species identification. Our research also demonstrates that machine learning approaches show a relatively high performance in species detection. Our approaches prove promising for wildlife surveys using drones in different ecosystems in tropical forests.

Efforts to release animals resulting from evacuation and rehabilitation into their natural habitats are important practices in wildlife conservation. Before releasing the animals, it is important to assess the habitat suitability of the areas to support the existence of the animals in the long run. Yet, there is limited study of habitat suitability assessment on national parks as release locations for wild animals. This study aimed to assess the suitable habitat of five charismatic animal species, i.e., Panthera pardus melas, Hylobates moloch, Prinonailurus bengalensis, Nycticebus javanicus, and Nisaetus bartelsi, in Gunung Halimun Salak National Park using Maxent, and to determine potential locations for releasing animal’s species. Models for the P. p. melas show 47,619 ha and 21,391 ha, respectively, suitable as habitat and potential release location, for H. moloch, each is 57,537 ha and 33,471 ha, for P. bengalensis, each is 25,460 ha and 17.189 ha, for N. javanicus, each is 29,848 ha and 15,578 ha, and for N. bartelsi, each is 44,426 ha and 25,660 ha. Our study shows that a suitable habitat can be critical in choosing a wildlife release site. Further consideration of conflict mitigation and practicalities is required to achieve the long-term existence of released species.
