Abstract. Sudaryanto FX, Hardini J, Kalih LATTWS, Asrori MM, Suana IW. 2019. Bird communities and vegetation composition in Nusa Penida, Bali, Indonesia. Biodiversitas 20: 3676-3683. A study on bird community and vegetation composition in Nusa Penida was carried out to determine its diversity, conservation status, and habitat as an effort to conserve and develop birdwatching ecotourism in Nusa Penida. The study was conducted in Tembeling forest and Ped agroforestry. By using the point count method, we found 80 species of birds: 70 species in Tembeling forest and 79 species in Ped agroforestry. Fourteen species of birds are protected by Indonesian law. According to the IUCN Red List of Threatened Species, four species are Critically Endangered and one species is classified as Near Threatened. We also found eight species of migratory birds. Diversity of birds in Nusa Penida was high. Individuals of each bird species was spread evenly, except Hirundo rustica, Hirundo tahitica and Streptopelia chinensis were dominant. Twenty-five species of trees were found in Tembeling, while in Ped were found 22 species. These vegetations were provided birds with good resources for foraging, resting, and nesting.

AbstractAn estimated 19% of the world's 9,856 extant bird species are migratory, including some 1,600 species of land- and waterbirds. In 2008, 11% of migratory land- and waterbirds were classed by BirdLife International as threatened or near-threatened on the IUCN Red List. Red List indices show that these migrants have become more threatened since 1988, with 33 species deteriorating and just six improving in status. There is also increasing evidence of regional declines. Population trend data show that more Nearctic–Neotropical migrants have declined than increased in North America since the 1980s, and more Palearctic–Afrotropical migrants breeding in Europe declined than increased during 1970–2000. Reviews of the status of migratory raptors show unfavourable conservation status for 51% of species in the African–Eurasian region (in 2005), and 33% of species in Central, South and East Asia (in 2007). Land-use change owing to agriculture is the most frequently cited threat affecting nearly 80% of all threatened and near-threatened species. However, while agricultural intensification on the breeding grounds is often proposed as the major driver of declines in Palearctic–Afrotropical migrants, some species appear to be limited by the quantity and quality of available habitat in non-breeding areas, notably the drylands of tropical Africa. Forest fragmentation in breeding areas has contributed to the declines of Nearctic–Neotropical migrants with deforestation in non-breeding areas another possible factor. Infrastructure development including wind turbines, cables, towers and masts can also be a threat. Over-harvesting and persecution remain serious threats, particularly at key migration locations. Climate change is affecting birds already, is expected to exacerbate all these pressures, and may also increase competition between migratory and non-migratory species. The conservation of migratory birds thus requires a multitude of approaches. Many migratory birds require effective management of their critical sites, and Important Bird Areas (IBAs) provide an important foundation for such action; however to function effectively in conserving migratory species, IBAs need to be protected and the coherence of the network requires regular review. Since many migratory species (c. 55%) are widely dispersed across their breeding or non-breeding ranges, it is essential to address the human-induced changes at the wider landscape scale, a very considerable challenge. Efforts to conserve migratory birds in one part of the range are less effective if unaddressed threats are reducing these species' populations and habitats elsewhere. International collaboration and coordinated action along migration flyways as a whole are thus key elements in any strategy for the conservation of migratory birds.

Abstract. Isworo S, Oetari PS. 2020. Mangrove vegetation and bird communities around Tegal Port, Central Java, Indonesia. Biodiversitas 21: 1551-1560. The ecological balance in Tegal harbor area needs to get serious attention due to the impacts of Tegal Port activities. For this purpose, the diversity of mangrove and avifauna (bird) can be used as bio-indicators of the ecological stability of the area. This study aimed to assess and analyze the diversity of plants and avifauna (birds) that live in mangrove and coastal zones around Tegal Port development area. Data collection was conducted using purposive random sampling method on two sites for vegetation and three sites for avifauna. The importance value index, Shannon-Wiener diversity index and Sorensen’s similarity index was calculated for the vegetation. For birds, we calculated the diversity and similarity index as well as identified their conservation status based on the IUCN Red List, CITES and government regulations. In terms of vegetation, Rhizophora mucronata and Avicennia marina dominate Site 2 (Tegalsari) while Casuarina equisetifolia and R. mucronata dominate Site 3 (Alam Indah Beach). Overall, the vegetation has low biodiversity index and similarity between sites is also low. For bird, there are 37 species from 18 families. Site 1 (Muara Reja) has the highest number of species with 29 species, followed by Site 2 (Tegalsari) with 25 species, and Site 3 (Alam Indah Beach) with 22 species. The three sites have moderate diversity index and there is high similarity index between sites. All bird species found in the study sites are listed as Least Concern under IUCN Red List, while there are two species protected under national protection law, i.e. Ardea alba and Glareola maldivarum. In general, the condition of mangrove vegetation around Tegal Port has low diversity. This suggests that the pressure on the environment is quite high, causing only few plant species to be able to live and dominate the ecosystem. The limited vegetation also causes birds community, especially the protected A. alba and G. maldivarum in Site 2, becomes increasingly difficult to find, because places to find food, breeding places and places to rest are disturbed.

AbstrakKawasan kampus Institut Teknologi Sumatera (ITERA) sedang mengalami perkembangan fisik yang pesat, seperti pembangunan gedung perkuliahan, laboratorium, asrama, juga embung untuk sumber air. Informasi mengenai keanekaragaman hayati di ITERA sendiri belum banyak diteliti, salah satunya adalah keanekaragaman burung. Burung merupakan hewan besar yang cukup sensitif dengan perubahan lingkungan. Penelitian ini dilakukan untuk mendapatkan data mengenai keanekaragaman burung di ITERA untuk memberikan informasi dasar. Metode yang digunakan adalah teknik point count, diterapkan pada lima stasiun utama yang dipilih berdasarkan pusat aktivitas pembangunan. Analisis yang digunakan adalah indeks keanekaragaman, kemerataan, juga kelimpahan. Selain itu, status konservasi dan tipe pakan jenis burung dianalisis menggunakan data sekunder. Hasil penelitian menunjukkan terdapat 19 jenis burung dari 16 famili. Keanekaragaman jenis burung berdasarkan indeks Shannon-Wiener tergolong sedang dan kemerataan jenis merata. Dari kategori kelimpahan yang digunakan terdapat dua jenis burung yang umum ditemukan. Bersumber pada PP No. 7 tahun 1999, terdapat empat jenis burung di ITERA yang termasuk ke dalam kategori dilindungi dan satu jenis termasuk kategori Appendix II di CITES. Feeding guild burung di ITERA didominasi tipe omnivora dan insektivora. AbstractInstitut Teknologi Sumatera (ITERA) campus area is undergoing rapid physical development, such as the construction of lecture buildings, laboratories, dormitories, as well as reservoirs for water sources. Information on biodiversity in ITERA has not much studied, one of which is bird diversity. Birds are large animals that are quite sensitive to environmental changes. This study aims to obtain data on bird diversity at ITERA to provide the baseline information. The method used is a point count technique, applied to five main stations selected based on the center of development activities. The analysis used is an index of diversity, evenness, and abundance. Besides, the conservation status and feed type of bird species were analyzed using secondary data. The results showed that there were 19 species of birds from 16 families. The Shannon-Wiener diversity index classified the bird community as a moderate, and the community evenness index was stable. From the abundance category, two types of birds commonly found. Based on PP No. 7 of 1999, there are four species of birds in ITERA, which included in the protected category and one species, including the Appendix II category in CITES. Omnivorous and insectivorous types dominate bird guild feeding in ITERA.

Penelitian ini bertujuan untuk mengetahui respon komunitas burung terhadap keberadaan Pembangkit Listrik Tenaga Panas Bumi Kamojang. Kami membandingkan keanekaragaman dan kekayaan jenis burung pada lokasi yang terdampak (DL) dan tidak terdampak (TL) di Wilayah Kerja Panas Bumi Kamojang, Cagar Alam Kamojang dan Taman Wisata Alam Kamojang di Kabupaten Bandung Provinsi Jawa Barat. Lokasi yang terdampak berada di sekitar sumur produksi atau pembangkit listrik tenaga panas bumi (30 sampel) sedangkan lokasi yang tidak terdampak adalah dengan jarak 3.000 m sampai 9.000 m dari fasilitas tersebut (42 sampel). Pengumpulan data dilakukan selama dua musim; musim kemarau dan penghujan (2015-2016). Kami mengumpulkan data komunitas burung dan data habitat dengan metode point count yang ditempatkan secara sistematis di setiap lokasi. Kami menemukan 124 spesies burung yang terdiri dari 35 famili dan 16 spesies di antaranya adalah burung endemik di Pulau Jawa. Dua puluh tiga spesies dilindungi oleh undang-undang di Indonesia, sembilan spesies termasuk dalam daftar lampiran CITES dan lima spesies masuk dalam Daftar Merah Spesies Terancam IUCN tahun 2017. Terdapat perbedaan respon antara komunitas burung di lokasi terdampak dan tidak terdampak yang ditunjukkan dengan perbedaan rata-rata jumlah spesies, jumlah individu masing-masing spesies, indeks keanekaragaman ShannonWiener. Lokasi tidak terdampak memiliki nilai lebih tinggi pada parameter ini dibanding lokasi yang terkena dampak. Demikian juga, jumlah spesies, jumlah individu vegetasi dan indeks keanekaragaman hayati ShannonWiener pada lokasi TL memiliki nilai rata-rata lebih tinggi daripada lokasi DL. Hal ini membuktikan bahwa meskipun panas bumi dianggap sebagai energi ramah lingkungan namun dalam penggunaannya masih berdampak pada keanekaragaman hayati di sekitarnya terutama untuk jenis burung. Response of Bird Community to Kamojang Geothermal Power Plant, Bandung, West JavaAbstractThis study aimed to investigate the response of bird communities on the presence of geothermal power plant of Kamojang. We compared the bird diversity and richness of affected (DL) and not affected (TL) in Kamojang Geothermal Working Area, Kamojang Nature Reserve and Kamojang Nature Park in Bandung regency of West Java Province. The affected sites were surrounding production wells or geothermal power plants (30 samples) whereas not affected sites were with distance of 3,000 m to 9,000 m from those facilities (42 samples). The data collection was carried out during two seasons; dry and rainy season in (2015-2016). In each site, we collected bird community data and habitat data with the point count method which was placed systematically on each sites. We found 124 birds species belongs to 35 families with 16 endemic species in Java Island. Twenty three species are protected by Indonesian law, with nine species are in the CITES appendix list and five species are listed in the IUCN Red List of Threatened Species of 2017. There was a difference of responses between bird communities in the affected and not affected sites which is indicated by differences in the mean number of species, number of individuals in each species, and Shannon-Wiener's diversity index. The not affected sites had higher value on these parameters than the affected sites. Similarly, number of species, number of individual vegetation, and Shannon-Wiener biodiversity index in TL sites had higher mean values than DL sites. This proves that although geothermal is considered as environmentally friendly energy but in its utilization it still has an impact on the surrounding biodiversity especially for bird species.

Abstract The Mandalika Special Economic Zone (SEZ) was designated as a tourist area in 2015. The development of the Mandalika area directly impacts the sustainability, diversity of species, especially birds that make mangroves their habitat. The study aims to investigate the value of bird species diversity in mangrove habitats as bioindicators. Furthermore, the research has been carried out for three months, from March to May 2021. Research data collection uses the roaming method, and data analysis uses bird community structure analysis (Diversity Index). In this study, 33 species of birds were found. Furthermore, it was found that six species of birds are protected wildlife. In addition, 16 are migratory birds, and 27 are Least Concern (LC) bird species; four species have Near Threatened (NT) status. Meanwhile, the Index of bird community structure is H’ 2.7, uniformity E 0.8, and dominance C 0.9. The value of the bird community structure in the Mandalika SEZ shows the condition of mangrove habitat in the moderate damage category. Therefore, there needs to be an effort to preserve mangroves involving the community, government, and Indonesia Tourism Development Corporation (ITDC) area managers.

<p>Bird communities are the composition of several bird species that live together in the same place, time and interact with other birds. The diversity of birds in an area can be used as an indicator of stabilizing an area. Changes of vegetation structures due to logging practices can affect the availability of resources for bird communities. The objective of the research was to examine diversity, richness, bird species abundance and bird community similarity at HS1 (logged forest 1974), HS2 (logged forest 1989/1990) and HS3 (fully logged forest 1989/1990) in Seblat Nature Recreation Park (SNRP). The research was conducted in July – September 2013. Data collection was conducted by point count method (total 36 points) and mist net method (total 4752 nets hours). The Research showed 85 bird’s species from 33 families were recorded. HS2 was highest value of diversity and richness (H ‘= 3.63, DMG = 10.07). The highest relative abundance species in HS1 was Emerald Dove (Chalcophaps indica), while HS2 and HS3 were Slender-billed Crow (Corvus enca). The bird community similarity was highest in HS2 and HS3 (ISj = 0.58).</p><p><strong>How to Cite</strong></p><p>Susanto, E., Mulyani, Y. A., &amp; Suryobroto, B. (2016).

SummaryOver the past half century, grassland birds in Europe have declined dramatically and in order to maintain and restore their populations it is critical to understand how habitat structures and quality within pastures affect birds. This study investigated the effects of habitat structure and pasture abandonment on grassland birds in IBA Ponor, western Bulgaria. Birds were sampled using the point count method at 143 randomly located circular plots and a total of 1,401 observations of birds from 31 species were recorded. The results showed that habitat complexity, management and landscape position influenced bird community structure and species occurrence within the upland pastures. Extensively grazed pastures supported higher structural complexity of vegetation cover and higher bird-species richness and diversity compared with abandoned ones. Moreover, bird species with a preference for grazed rather than abandoned pastures had higher conservation status and most were associated with shrub cover. To maintain high levels of avian diversity, habitat complexity within pastures should be maintained through extensive grazing, to ensure availability of scrub vegetation wherever possible. Finally, this study provided evidence that agri-environmental schemes should not be directly extrapolated from one country or region to another without been tested first, because within the same management, differences in habitat structural characteristics may exist due to the landscape and socio-economic characteristics of the region.

Using the point count method, linear mixed models, Shannon’s diversity index, and Bray-Curtis cluster analysis, we conducted a study of the effect of urban fabric layout on bird diversity and distribution in northern Rwanda. The results showed a significant effect of city landscapes on bird richness and relative abundance; residential neighborhoods, institutional grounds, and informal settlements had the highest species diversity in comparison to other microlandscape types. Riversides were characterized by specialized bird species, commonly known to be restricted to wetland environments. Built-up areas and open field landscapes had comparable results. One Albertine Rift endemic bird species, the Ruwenzori Double-collared Sunbird (Cinnyris stuhlmanni), was recorded. Three migratory birds were found in Musanze city for the first time: the Common Sandpiper (Actitis hypoleucos), the Spotted Flycatcher (Muscicapa striata), and the Willow Warbler (Phylloscopus trochilus). Two bird species have not been previously reported in Rwanda: the Garden Warbler (Sylvia borin) and the Lesser Spotted Eagle (Aquila pomarina). The implications of this study are particularly relevant to urban decision makers who should consider the existence of a great diversity of avian fauna when developing and implementing master plans, especially when villages and cities are in proximity of protected areas or natural reserves.

Birds are important species that play a role in maintaining ecosystem stability. The land-use functions by humans can cause decreasing diversity of bird species. The purpose of this study was to identify species richness, species diversity, and conservation status of birds in Maron Beach, Semarang. The research was conducted in January 2017 using the point count method by five points. Observations were made at 06.00 - 10.00 WIB with a duration of 15-30 minutes for each point. The results showed that there were 42 bird species from 20 families. The species richness index (R1) showed a 6.629 value which is classified as a high category. Diversity index (H ') showed 2,915 value which is classified as a medium category. Conservation status of bird species that were protected by PP No. 7 1999, there were 7 bird species. Protected bird conservation status by P 106 2018, there were 3 bird species. The conservation status by IUCN is classified into 2 categories, that were Near Threatened (NT) and Least Concern (LC). The conservation status of international trade according to CITES indicates that no species are included in the list, but most of the bird species are traded locally.
