    Indonesia is the largest archipelagic country in the world, with 17,000 islands of varying sizes and elevations, from lowlands to very high mountains, stretching more than 5000 km eastward from Sabang in Aceh to Merauke in Papua. Although occupying only 1.3% of the world’s land area, Indonesia possesses the third-largest rainforest and the second-highest level of biodiversity, with very high species diversity and endemism. However, during the last two decades, Indonesia has been known as a country with a high level of deforestation, a producer of smoke from burning forests and land, and a producer of carbon emissions. The aim of this paper is to review the environmental history and the long process of Indonesian forest management towards achieving environmental sustainability and community welfare. To do this, we analyze the milestones of Indonesian forest management history, present and future challenges, and provide strategic recommendations toward a viable Sustainable Forest Management (SFM) system. Our review showed that the history of forestry management in Indonesia has evolved through a long process, especially related to contestation over the control of natural resources and supporting policies and regulations. During the process, many efforts have been applied to reduce the deforestation rate, such as a moratorium on permitting primary natural forest and peat land, land rehabilitation and soil conservation, environmental protection, and other significant regulations. Therefore, these efforts should be maintained and improved continuously in the future due to their significant positive impacts on a variety of forest areas toward the achievement of viable SFM. Finally, we conclude that the Indonesian government has struggled to formulate sustainable forest management policies that balance economic, ecological, and social needs, among others, through developing and implementing social forestry instruments, developing and implementing human resource capacity, increasing community literacy, strengthening forest governance by eliminating ambiguity and overlapping regulations, simplification of bureaucracy, revitalization of traditional wisdom, and fair law enforcement.

    The high rate of deforestation and fragmentation of elephant habitat on Sumatra Island has triggered human-elephant conflict (HEC) in Sumatra Island, Indonesia. This conflict brings negative impacts on humans and elephants. Despite numerous efforts having been made to solve this problem, the HEC continues to occur in the remaining elephant enclave every year. The harmonious coexistence between humans and elephants could be improved through HEC mitigation programs. The aim of this paper was to review information on HEC in Sumatra Island, investigate the causes and implications of HEC, review existing HEC mitigation methods, and formulate strategies to improve the harmonious coexistence between humans and elephants. The best strategies to create successful human and elephant coexistence are strengthening the institutions and policies, restoring the habitat, developing wildlife corridors, establishing Essential Ecosystem Areas (EEA), community empowerment through ecotourism, providing legal access to forests through Social Forestry (SF), and providing compensation schemes for conflict victims.

    IOP Publishing
    Abstract Birds played an essential role in the life cycle. This study aimed to determine the bird diversity in coal mining reclamation areas with different ages of reclamation plants: one, four, and eight years old, located in East Kalimantan, Indonesia. The bird diversity was determined using two methods: direct observation and capture-released using mist nets. The birds captured by mist nets were identified, and morphometric measurements were conducted. The results showed 26 species of birds found in this study. Birds species were dominated by Blue-throated bee-eater (Merops viridis), Yellow-vented bulbul (Pycnonotus goiavier), Asian-glossy starling (Aplonis panayensis), and Javan myna (Acridotheres javanicus). The bird’s diversity in the reclamation area with four years of reclamation plants was higher than the other areas. However, the number of birds in the reclamation area with eight years of reclamation plants was the highest. Differences in habitat conditions in the three research areas might cause a low similarity index of bird diversity. Javan myna and Yellow-vented bulbul were found in all research sites. In conclusion, pioneer bird species were observed during the early process of post-coal mining reclamation. The existence of cover crops was essential as a source of food for the birds and nests.

  • The diversity of plant species in the proboscis monkey's habitat as a species reference for habitat restoration

    IOP Publishing
    Abstract Most of the Proboscis monkey (Nasalis larvatus) habitat is outside the protected area, so the potential for destruction is high. One of the efforts to improve its habitat is habitat restoration. This study aims to determine plant species for proboscis monkey habitat restoration based on reference habitats. The research was conducted at eight locations in East Kalimantan, Indonesia i.e. Kuala Samboja, Mahakam Delta, Suwi River, Ohong River, Berau Delta (mangrove and riverine), Sungai Wain, and Kutai National Park. Vegetation analysis with line-plot sampling method with a total sample of all locations of 11.7 ha. The results showed that the habitat included three main types: mangrove, riverine, and riverine-near coastal. A total of 152 tree species, 41 of which were potential proboscis monkey feed. The highest plant species diversity value was in the riverine forest-Berau Delta of 1.25, while the lowest was in the mangrove forest-Berau Delta of 0.54. Species that are a food source and have good adaptation in riverine habitat are Vitex pinnata, Dillenia excelsa, Garcinia spp, Heritiera littoralis, Ilex cymosa, Cerbera manghas, Hevea braziliensis, and Sonneratia caseolaris. Whereas in mangrove habitat are Avicennia alba, A. officinalis, Bruguiera gymnorrhiza, B. parvifolia, Rhizophora apiculata, and S. alba. They are recommended for habitat restoration.

    Suwi River, which is a part of Kenohan-Suwi Wetland in East Kutai District, East Kalimantan is a habitat of endangered animals such as proboscis monkey (Nasalis larvatus). Therefore, this study aims to determine the habitat, distribution, threats, and conservation efforts of proboscis monkeys in the Suwi River. To achieve this, the boat survey method was adopted, while plot line samples were used for vegetation analysis. The results showed that the habitat is composed of riverine plant species, such as prupuk (Mallotus sumatranus; IV=121.84%), bungur (Lagerstroemia speciosa; IV=37.10%), and rengas (Gluta renghas; IV=34.76%). Furthermore, a minimum of 12 monkey groups was distributed in this area, however, their population is unknown. Illegal hunting by local people has caused population decline, this is in addition to other threats, such as habitat conversion, forest fire, and invasive plant species. The effort to protect the habitat of proboscis monkeys was made by developing Essential Ecosystem Areas Suwi-Mesangat. Other institutions that committed to protecting this area include Federal and local government, NGO, local community, and palm oil company

    IOP Publishing
    Abstract Wehea-Kelay landscape is an unprotected area, located on the eastern part of Borneo Island. It is managed by 7 unit managements, which were mostly timber companies. We compiled and collated our avifauna data with previous studies. We recorded 273 bird species belonging to 60 families during field work. 61 species were protected based on Indonesian regulations. Among of them were threatened species with small population such as Great argus Argusianus argus, Storm’s stork Ciconia stormi, and Helmeted hornbill Buceros vigil. Although Wehea-Kelay is dominated by timber concessions, the landscape can still provide habitat for many species of bird. Nevertheless, anthropogenic pressures i.e. illegal hunting have increased and become a threat for birds particularly commercially traded species such as Leafbirds Chloropsis spp, White-rumped Shama Copsychus malabaricus, Common hill myna Gracula religiosa, and also Helmeted hornbill Buceros vigil.

    IOP Publishing
    Abstract The proboscis monkey is an endangered primate endemic to Borneo. Most of their habitats are outside conservation areas and are under threat from conversion to other land uses, such as those found in the Berau Delta. Habitat loss and destruction significantly affect the quality and viability of the proboscis monkey population. This study aims to determine land cover and proboscis monkey habitat types in Berau Delta. Land cover was obtained from the interpretation of the Lansat 8 OLI 2019 satellite image. Vegetation data were collected using a line plot transect method and continued with cluster analysis. The results showed that mangrove forest has the largest coverage (35.92%), followed by secondary forest (17.10%) and riparian forest (12.96%). At least 74 species of woody plants belonging to 61 genera and 37 families in a 2.4 ha observation plot. The range of species diversity index was from 0.80 to 2.88, and; evenness index values range from 0.58 to 0.82. The habitat was categorized into two main clusters: mangrove cluster (Buasin Cape, Guntung Estuary) and riverine cluster (Lati River, Saodang Kecil Island, Batu-Batu, Bebanir Lama). The mangrove forest habitat consists of Rhizophora mucronata, R. apiculata, Bruguiera sp, Sonneratia alba, and Avicennia alba. The riparian habitats are dominated by Sonneratia caseolaris, Vitex pinnata, Cerbera manghas, Brownlowia argentata, Heritiera littoralis, Syzygium lineatum, Nauclea officinalis, Xylocarpus granatum, Syzygium sp.1, and A. alba. The average of total and lower branches height of trees in the Lati River and Basin Cape were higher than in other habitats, forming a continuous canopy.

    The proboscis monkey (Nasalis larvatus) is an endemic species to Borneos’ island and is largely confined to mangrove, riverine, and swamp forest. Most of their habitat is outside the conservation due to degraded and habitat converted. Habitat loss is a significant threat to a decreased in the monkey's population. Berau Delta is an unprotected habitat of proboscis monkey, lacking in attention and experiencing a lot of disturbances. This study was conducted on April – August 2019; with aims of the study is to determine Species Distribution Modeling (SDM) for identifying proboscis monkey habitat suitability in Delta Berau, East Kalimantan. The MaxEnt algorithm was used to produce a habitat suitability map based on this species’ occurrence records and environmental predictors. We built the models using 208 points of proboscis monkey presence and 12 environment variables within the study area. Model performance was assessed by examining the area under the curve. The variables most influencing the habitat suitability model were the riverine habitat (60.9%), distance from the pond (16.0%), and distance from the coastline (5.2%). The proboscis monkey suitable habitat is only 9.32% (8,726.58 ha) from 93,631.41 ha total area. The appropriate habitat areas are Sapinang Island, Bungkung Island, Sambuayan Island, Saodang Kecil Island, Besing Island, Lati River, Bebanir Lama, Batu-Batu, and Semanting Bay. We provide some suggestions for the proboscis monkey conservation, which are local protection of uninhabited islands, participatory ecotourism management, and company involvement in protection and management efforts.
