Marshlands and backswamps are among the threatened habitats in Indonesia, along with mangroves, particularly in Java due to area development and land conversion. Muara Gembong is one of the remaining wetlands in Java and serves as one of the last refuges for the bird community in wetlands, particularly mangrove and marsh-associated birds. We observed bird communities and collected eleven habitat variables in three habitats, namely mangrove, marsh, and fishpond, to see which variable affects bird abundance and diversity most. We found out that the total number of plant species, along with the number of tree, understory, and shrub species, were the strongest factors affecting bird diversity in Muara Gembong. Separate analysis in each habitat, however, reveals that different abiotic factors also strongly correlate with bird diversity. Vegetation correlates strongly with bird diversity in mangroves and marshes, while pH and turbidity play a strong role in bird diversity in fishponds.

POWLING, A., PHILLIPS, A., PRITCHETT, R., SEGAR, S. T., WHEELER, R. & MARDIASTUTI, A. 2015. The vegetation of Lambusango Forest, Buton, Indonesia. Reinwardtia 14(2): 265 - 286. - Lambusango Forest is a tropical rainforest on the island of Buton, which lies close to south east Sulawesi. The forest covers an area of about 95.000 ha, with different parts of the forest having different levels of conservation protection. It lies on rocks of both calcareous (limestone) and non-calcareous (sandstone, conglomerate, peridotite and chert) nature, which give rise to soils with varying pH values, nutrient levels and water-holding capacities. The climate is seasonal, with a dry season of three months and considerable year-to-year variability due to El Nino and La Nina events. The vegetation on the different soils and in different habitats has been studied. Over 300 species of vascular plants found in the forest and surrounding areas are listed, including trees and shrubs, herbs, climbers, epiphytes, ferns and club-mosses. Two genera, Calamus with 18 species and Ficus with 29 species, are particularly species-rich, apparently due to their ability to occupy numerous edaphic and ecological niches. Species of these two genera are also good colonists and so better able to reach Buton in the recent past than other species. The plants of the forest indicate that Buton is floristically very similar to Sulawesi, with at least 83% of the species found in the forest also being known from Sulawesi. Most of the plant families and genera present on Buton are common in SE Asia, indicating colonisation primarily from that continent. Many fewer families and genera have colonised from the Australasian continent. The conservation of plant diversity is necessary for the forest to continue as a functioning ecosystem, to the benefit of the animals of the forest and also the local people.

PRITCHETT, R., PHILLIPS, A., MARDIASTUTI, A. & POWLING, A. 2016. Rattan diversity and broad edaphic niches in a tropical rainforest of Buton, Sulawesi, Indonesia. Reinwardtia 15(2): 99 – 110. — This paper attempts to answer the question: how can at least 20 species of rattan palms in the genus Calamus (family Palmae (Arecaceae)) co -exist in a rainforest? A survey of rattans was made in Lambusango Forest on Buton, an island close to south east Sulawesi, in Indonesia. Rattan species and numbers were recorded in 87 quadrats of 30 × 10 m, laid out along linear transects in habitats with a variety of soils. Evidence for edaphic (soil) niches was sought. Different rattan species were found to be adapted to soils with different conductivity and pH values. Standardised mean difference (d) scores were calculated for pairs of species based on their response to soil pH. Of the 66 pairs tested, 61 were found to be significantly different statistically. Such differences suggest, but do not prove, that many species occupy different edaphic niches. It was found that species which show a preference for soils with intermediate pH values (5.0 to 6.5) can grow in soils with a wide range of pH values, implying broad edaphic niches and that competition between these species is weak. Correspondence analysis shows that many species do not distinguish greatly between many soils with intermediate pH values. It is concluded that rattan species show evidence for having different edaphic niches, although the niches for many species are broad. It is speculated that many rattan species may be ecologically equivalent and that a weak version of ecological neutrality theory may apply.

Leptophryne javanica is a frog in West Java and Central Java. Threats to the presence of L. javanica in nature include volcanic activity and chytrid fungi. The population of L. javanica is not known for certain. This study aims to estimate the abundance of L. javanica in several streams of Mount Ciremai National Park and describe the habitat of this species. This research was conducted in Cisurian Waterfall, Cilutung Waterfall, Ciinjuk Spring, and Cilengkrang Waterfall using visual encounter methods combined with sampling transect. L. javanica was found mostly in Ciinjuk Springs with an abundance of 2.50 ± 3.09 ind /10 m. More males were found than females, except in the Cisurian Waterfall. The body size and weight of the females were larger than the males. The microhabitat of Ciinjuk Spring had an average of river currents of 0.34 m/s, river width of 0.8–1.2 m, river depth of 1.0–3.4 cm, and canopy density ranging from 54.17–100%. In addition to the spring, the waterfall was also a preferred habitat by L. javanica. Further research is needed in other waterfalls and rivers with microhabitat characteristics similar to Ciinjuk Spring.

The Javan hawk-eagle (Nisaetus bartelsi Stresemann, 1924), an endangered bird endemic to Java island, faces significant extinction risks due to habitat loss and illegal hunting. To address this, the Javan Hawk-eagle Sanctuary Center (JHESC) was established within Mount Halimun Salak National Park, Bogor Regency, West Java, Indonesia, to support in-situ and ex-situ conservation efforts, focusing on rehabilitation and release. This study observed rehabilitation practices at the centre from April 2022 to March 2023, particularly the adequacy of its facilities and infrastructure regarding cage, feed, and health management. These aspects are essential for rehabilitation success. Based on observations, nine cage types were employed and tailored to specific rehabilitation stages: acceptance, treatment, isolation, pre-training, training, habituation, education, translocation, and hard release. These cages were designed with varying sizes and numbers to fulfil the needs of each stage. The centre's feeding management was supported by a well-organized storage system that maintained feed quality through proper air circulation and cleanliness. The centre consistently supplied three primary feeds: mice (Mus musculus), rats (Rattus norvegicus), and marmots (Cavia porcellus). Comprehensive infrastructure facilitated health management, including an animal clinic, isolation and treatment rooms, an operating room, an examination room, and a laboratory. Additionally, the veterinary medicines were accessible and staffed by qualified veterinarians to ensure the eagles were healthy from arrival to release. These robust facilities and practices can position the centre as a leading example for ex-situ conservation, prioritizing animal welfare while rehabilitating and releasing Javan hawk-eagles, with expectations of further enhancing eagle conservation efforts.

Succession after disturbance can affect the response of the bird community at each stage of habitat succession. Research on the impact of succession on birds has never been done in Papua, so this research is needed to understand how birds can survive habitat changes. This study aimed to analyze bird communities and their responses to successional stages of habitats, i.e., shrubs, agriculture, mixed plantation forest, young secondary forest, old secondary forest, and primary forest. Data collection was done from January 2023 to October 2023. Bird data (species and numbers) were collected using the point count method. Vegetation data (species and density) were collected by using the plot method, and abiotic data (air temperature, humidity, and light intensity) were collected using a dry-wet thermometer and a lux meter. The Shannon-Wiener diversity indices (H') were calculated for birds and trees. Correlation of the bird data against habitat and abiotic parameters was calculated. There were 11,272 birds from 55 species belonging to 25 families in the study area. The young secondary forest had the highest bird number and diversity (44 species; H' = 3,424), in line with the Intermediate Disturbance Hypothesis. Bird communities generally have a strong correlation with vegetation but a weak correlation with abiotic data. In light of conservation importance, young secondary forest held the highest bird species richness, while the primary forest provided habitat for some species that are highly dependent on natural forests.
