Abstract

The Ranggawulung Urban Forest represents a critical green open space with substantial potential for biodiversity conservation within an urban context. This study aims to characterize the vegetation community structure and assess the conservation status of recorded plant species. Vegetation inventory was conducted using a quantitative approach based on growth stages at two sites: the Urban Forest Block and the Camping Ground Area. The analyses included the Important Value Index (IVI), Shannon-Wiener diversity index (H’), Margalef spesies richness index (Dmg), and evenness index (E). The analysis of species composition and structure revealed distinct patterns in the distribution of the IVI across locations and growth stages. Swietenia mahagoni demonstrated the highest IVI at the seedling growth stage within the urban forest block, as well as at the tree growth stage within the camping ground area. In contrast, within the urban forest block, Maesopsis eminii exhibited the highest IVI at the tree growth stage. Furthermore, in the camping ground area, Cyperus rotundus attained the highest IVI at the seedling and understory vegetation strata. The Shannon-Wiener diversity index (H’) in Ranggawulung Urban Forest indicates that the seedling and understory vegetation strata exhibit higher species diversity compared to the tree strata. The highest H’ value was recorded in the seedling and understory vegetation of the camping ground area (3.5), whereas the lowest was observed in the tree stratum of the camping ground (2.83). The species richness index (Dmg) displayed a similar pattern, with the highest value found in the seedling and understory vegetation of the camping ground (10.42) and the lowest in the tree stratum of the urban forest block (5.22). Meanwhile, the evenness index (E) was relatively high across all categories, peaking in the tree stratum of the urban forest block (0.93), indicating the most balanced distribution of individuals among species in this category. Four species were classified as thteatened acording to the IUCN Red List and CITES Appendices. These findings fulfill the study objectives and underscore the ecological value of the Ranggawulung Urban Forest as a biodiversity refuge, highlighting the need for sustained conservation actions and ecologically informed urban forest management.

Abstract

Fruit bats (family Pteropodidae) pollinate around 300 species of tropical plants of high economic value over a wide range of areas. This large role does not match the status of their population, which continues to decline due to habitat loss, particularly in urban areas. The Sumatra Institute of Technology (ITERA) campus, which is currently under development, may result in habitat changes that may affect bats. These concerns have led to the need for research into bat diversity on the ITERA campus. The result could be utilised to monitor and develop the environmental management of the campus. The research was conducted from May to September 2023 in five different habitat types. Data were collected using 3 mistnets and 3 night repetition each habitat. The data were analysed using indices of diversity, evenness and species richness. The study recorded 143 individuals of 7 species. The highest number of species and diversity was observed in the sengon and rubber habitat (6 species). The lowest number of species and diversity was found in the botanical garden (2 species).

Abstract

Mangrove forests are important for storing carbon dioxide (CO2) and reducing the effects of climate change. Indonesia possesses 20% of the global mangrove cover, which substantially impacts global climate mitigation efforts. However, understanding of the diversity of plant species in mangrove forests remains limited, as evidenced by the high rate of conversion of mangrove areas into aquaculture ponds, resulting in mangrove degradation. Our research in Pantai Mekar Village was conducted to augment information on mangrove plant species diversity in Indonesia, specifically in Bekasi Regency. Mangrove vegetation data were collected in Pantai Mekar Village, Muara Gembong, Bekasi from 8 to 12 July 2019. Data were collected using 2x2 m (seedlings and understory), 5x5 m (saplings), and 10x10 m (trees) plots. Importance value index (INP), Shannon-Wiener species diversity, evenness, richness, and carbon stock estimation were utilized to analyze the data. The study documented 21 species from 15 families. Species from the Acanthaceae family were predominant in the study site. Avicennia alba was the species with the largest biomass and carbon content. The estimated biomass contained in Mekar Beach is 380.42 tonnes/Ha with carbon sequestration of 190.21/Ha.

Abstract

Estimating forest biomass is essential for sustainable forest management and carbon monitoring. This study aimed to develop an aboveground biomass (AGB) estimation model by integrating multispectral Landsat-8 OLI imagery and field measurements in a 95.76 ha rehabilitation area near Rindam II Sriwijaya, Muara Enim, South Sumatra. Field data were collected using the National Forest Inventory Protocol, recording tree diameter and height to calculate AGB through species-specific allometric equations. Several vegetation indices (NDVI, EVI, SAVI, MSAVI, RVI, TVI, NDWI) were derived and analyzed on the Google Earth Engine (GEE) platform to identify the most responsive spectral indicator for biomass estimation.The analysis showed that AGB and carbon stocks varied across the rehabilitation site, reflecting differences in stand structure and vegetation moisture. Among all tested indices, NDWI demonstrated the highest correlation with AGB, indicating its effectiveness in capturing canopy water content and biomass variation under humid, mixed-vegetation conditions. These results emphasize the potential of GEE-based vegetation indices as a cost-efficient and replicable approach for monitoring biomass in tropical rehabilitation forests. NDWI proved to be the most suitable index for modeling forest biomass, offering a practical reference for applying similar remote sensing methods in other tropical regions to support large-scale forest carbon assessments

Abstract

Mangrove are important coastal ecosystems that provide a variety of ecosystem services and ecological functions. These ecosystem services include natural barriers that protect coastal areas from cyclones, tsunamis, and erosion. Habitats for breeding, foraging, and nursery for various species of aquatic and tereterial species. The benefits provided by mangrove are contrast to the rate of degradation. Various parties have a responsibility to contribute to efforts to maintain a sustainable environment. Biodiversity has been globally recognised as one of the determining factors for the sustainability of an ecosystem. The study aims to assess the diversity of herpetofauna species in the Cukunyinyi Mangrove ecotourism area as an instrument of environmental monitoring. The method in this study was the Visual Encounter Survey (VES). The diversity of herpetofauna (H') observed in the area was 1.06 inside the Ecotourism Area and 0.56 outside the ecotourism area. The indices of species richness (Dmg) in each area were 1.24 and 0.72. The two regions have evenly distributed with an evenness value of more than 80%. No species protected under national regulation, two species whose trade was restricted internationally and included in the CITES Appendix II.

Abstract

Indonesia known for its high biodiversity, is home to various species of wildlife, with 17% of the world's wild animals found in its territory. However, this wealth makes Indonesia one of the major suppliers of both legal and illegal wildlife trade, which threatens conservation efforts. This study aims to identify the potential of wildlife trade, health factors, and the welfare of traded animals. Conducted in Bandar Lampung in February 2022, the research employed direct observation through structured interviews with pet shop owners, as well as document studies. The findings indicate that despite a post-pandemic decline, wildlife trade in the region still holds significant potential. Health factors, such as mouth ulcers in pythons and metabolic diseases in geckos, pose major challenges, although adequate care is provided in these shops. Animal welfare remains a critical concern, as dependence on wild-caught animals from the wild threatens their sustainability. This study emphasizes the importance of implementing sustainable management practices and adhering to existing regulations to ensure the continuity of wildlife trade in Indonesia

Abstract

Hydropower plants are often considered a negative factor affecting biodiversity conservation; however, some studies have noted that they can also serve as biodiversity refugia from the pressures of forest cover change in the surrounding areas. This study aimed to identify the biodiversity within the Besai Hydropower Plant (PLTA Besai) concession area. Data collection was performed using several methods, including strip transects, trapping, and track detection for mammals; a point count combined with transects for birds; and visual encounter surveys for amphibians and reptiles. The results recorded the presence of 88 terrestrial vertebrate species, comprising 17 mammal species, 39 bird species, and 32 herpetofauna species (17 amphibian species and 15 reptile species) within the concession. The study area is inhabited by at least 5 nationally protected species, 8 threatened species according to the IUCN Red List, and 10 species listed in the CITES Appendices. Besai Hydropower Plant concession has the potential to act as a refugium from the threat of land cover change, particularly conversion to plantations, which is a common occurrence around the study area.

Abstract

The Way Besai Hydroelectric Power Plant (PLTA) is located in West Lampung Regency, Lampung Province, with a capacity of 90.4 MW and utilizes water from the Way Besai River. The availability of stable water discharge is highly dependent on the vegetation conditions in the catchment area. This study aims to examine the diversity of flora and vegetation sustainability in the Way Besai hydropower plant area using an exploration method divided into six observation lines. The results showed that there were 57 types of plants belonging to 21 families. The most common species are sonokeling (Dalbergia latifolia) with 140 individuals and seripit (Crypteronia paniculata) with 113 individuals. The families with the highest number of species are obtained from the families Moraceae and Fabaceae. The types of the Moraceae family are dominated by Ficus spp., which acts as a source of animal feed, while from the Fabaceae family, there are more types of multipurpose plants (MPTS). The diversity of species and evenness of flora around the Way Besai hydropower plant is relatively high, as shown by the diversity index value (H') of 3.281 and the evenness index value (E) of 0.812. Although this value is relatively high, the maintenance and conservation of flora still needs to be carried out intensively to maintain the stability of the water discharge of the Way Besai River. These results confirm that the vegetation around the Way Besai hydropower plant is still relatively sustainable, but sustainable conservation efforts are needed to control land conversion that has the potential to reduce the water discharge of the Way Besai River.

Abstract

Bats (Chiroptera) are the only type of mammal that can fly. Bats have high mobility in their foraging activities, such as flowers, fruits, nectar, and insects at night. Indonesia has several species of bats that are widely distributed across several major islands, such as Sumatra, Java, Kalimantan, Sulawesi, and Papua. Kelimutu National Park has various potential habitats for flora and fauna that can support the life of bats. Information about bats in Kelimutu National Park is not yet available, so this research was conducted to obtain initial information/data on bat species in Kelimutu National Park. This research aims to describe the level of diversity of bat species (Chiroptera), including species names, local names, and family names, in Kelimutu National Park. This research uses direct observation methods with tools such as harps and mist nets, and vegetation analysis. The results show that the most abundant species is the Nusa tenggara short-nosed fruit bat (Chinopterus nusatenggara), with 35 individuals, and the highest number of findings was in the Wolojita resort with 12 individuals. Meanwhile, the least found species was the wall-roosting mouse-eared bat (Myotis muricola), with a total of 14 individuals found across all five locations, indicating that each location has varying levels of diversity. The bats found in this study have a Least Concern (LC) conservation status, although they are not currently facing serious extinction threats in the wild, it is still important to maintain their habitats to remain stable.
