Birds are one of the most important components of biodiversity that has huge ecological, economical, and esthetic values. The main objective of this study was to assess diversity and species composition of bird community in Kafta Sheraro National Park, Northern Ethiopia. Data were collected from August 2017 to March 2018 in the national park. Point count method was employed to collect data on bird species diversity and species composition. Direct observations of birds and discussion with local people and scouts to assess potential threats of avifauna in the park were made. Shannon diversity index was used to calculate the species diversity. A total of 158 bird species belonging to 52 different families and 20 orders were identified. Of the recorded species, there were 76.6% residents, 15.8% Palaearctic migrants (PM), 5.7% Intra-African migrants (IM), and 1.9% partial migrants. Accipitiridae (11.4%) had the highest species followed by Columbidae, Estrilidae, and Ploceidae with 7%, 5.7%, and 4.4% species, respectively. The highest Shannon–Weiner diversity index (H′ = 4.50) was recorded during February while the lowest (H′ = 2.18) was recorded during March. Species richness of the park showed no significance difference among the study months (χ2 = 10.046, df = 5, P>0.05). Agricultural expansions, fire, livestock grazing, mining, and poaching were the major threats of the park bird species. Kafta Sheraro National Park is one of the areas with high avian composition in Ethiopia. In the park, wildlife watching in general and ornithological tourism in particular should be developed. Anthropogenic disturbances should also be minimized to conserve avian diversity of the park.

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.

Limited information is available on the species composition, above ground biomass and its relations to grazing in a trans-Himalayan rangeland. Its assessment is essential for long term conservation and management. In the present study, we compared species composition, phenology, diversity index and biomass between controlled (without grazing) and open (free grazing) plots to assess the effects of grazing in the selected experimental sites of Upper Mustang during July and November 2005. Species encountered were classified as high, medium, low and non palatable and in three life form categories-grasses, shrubs and forbs. The experimental sites are dominated by forbs (80%) followed by grasses (15%) and shrubs (5%). Disturbance caused by grazing affects the phenological characteristics of the plant community. Result also reveals that species diversity, maximum possible diversity, evenness and species richness was higher in the grazed plots during July and November. A comparison of the aboveground biomass in July showed that mean percentage biomass of high, medium and low palatable species is higher in ungrazed plots. In November, the percentage biomass of only medium palatable species was higher in ungrazed plots and rest of the category is higher in grazed plots. Significant difference in July, a peak growing seasons for most of the plant species in the region reveals that the pasture has impact of livestock grazing.

There exists limited information on biodiversity including avifaunal diversity and habitat condition in community forests (CF) of Nepal; thus we aimed to fulfill such gaps in Tibrekot CF of Kaski district. We used the point count method for assessing bird diversity and laid out a circular plot size of radius 5-m within 15-m distance from each point count station for recording the biophysical habitat characteristics. Bird species’ diversity, richness and evenness were calculated using popular indexes and General Linear Model (GLM) was used to test the respective effect of various biophysical factors associated with the richness of bird species. In total, 166 (summer 122, winter 125) bird species were recorded in 46 sample plots. The Shannon-Wiener diversity index was calculated as 3.99 and 4.09, Margalef’s richness index as 16.84 and 17.53 and Pielou’s evenness index as 0.83 and 0.84 for summer and winter, respectively. The influencing factors for richness of bird species were season (χ21, 90= 112.21; P= 0.016) with higher richness in the summer season and low vegetation cover (χ21, 89= 113.88; P= 0.0064) with higher richness in lower percentage cover. Thus, community managed forest should be protected as it has a significant role in increasing bird diversity, which has potential for attracting avifaunal tourism for the benefit of the local communities.

Abstract. Izzati U, Hasibuan HS. 2019. Riparian tree and bird diversity in Cisadane River, South Tangerang City, Indonesia. Biodiversitas 20: 595-603. Riparian is a riverbank area that has unique characteristics. It is a combination of terrestrial with aquatic habitats so that riparian ecosystems have high biodiversity values. Riparian is included in a protected area that is naturally designated for vegetation, but in reality, riparian areas, especially in urban areas, have a lot of conversion of land functions by humans so that it can disrupt diversity of tree and bird species. This study aims to identify the diversity of tree and bird species and the correlation between the two. Riparian length of Cisadane River, South Tangerang City is 20.15 km. The method used was plot line with size of 20 m x 20 m for tree data and line transect for bird data by systematic sampling with a random start then analyzed using Shannon Wiener index. The results obtained were found 22 tree species included in 11 families with species diversity index (H') of 2.707 and 40 bird species belonging to 25 families with species diversity index (H') of 2.794. The diversity of tree and bird species is classified as medium. The results of the analysis using the Pearson correlation between the diversity of tree with bird species obtained that there was no relationship between the two. Based on these results, riparian zones in urban areas need to be maintained and improved in quality so that the diversity of tree and bird species increases so as to create a stable ecosystem.

Abstract Lower mountain forest in the complex of Mount Bulusaraung Bantimurung Bulusaraung National Park, is a one of bird’s habitat in the South Sulawesi. This area is a tourist destination, especially mountain climbing activities. Thus, it is necessary to know the diversity of animals, especially birds on this hiking trail, so that the information can be used to support ecotourism activities. This study aims to analyze the diversity of bird species in the complex of Bulusaraung Mountain, Bantimurung Bulusaraung National Park in order to support ecotourism activities. This research was conducted from April to June 2018. Data was collected using the line transect method on three lines, namely the Balleanging, Kattokaddaro and Tompobulu lines. The second and third paths are hiking trails, while the rest are trails leading to community agricultural areas. The geographical position of the transect line was recorded using GPS. The GIS method was used to generate a bird watching trail map. Data analysis was carried out to calculate the individual density and frequency of bird presence. In addition, the species diversity indices, species evenness indices, and species richness indices were also calculated. The results showed that there were 44 species of birds found in the study area, which were 16 species in the Balleanging line, 27 species in the Kattokaddaro line and 37 species in the Tompobulu line. The highest bird species diversity indices value was found on the Tompobulu line (H' = 2.93), while on the Kattokaddaro line it was H' = 2.73 and the Balleanging H' = 2.55. The results of this study will support the management strategy in Bantimurung Bulusaraung National Park in order to harmonize the conservation of biological resources through ecotourism activities that involve local communities to increase their economic income.

Tropical forests have undergone extensive transformation because of increasing tourism development, in addition to historic clearing for agricultural and cattle grazing activities. Altogether, these activities have had an important effect on bird diversity, reducing the habitat available to many species. In this study, the role of tropical forest remnants located between different land use types was evaluated for species diversity, composition, and distribution of the bird community at Akumal region in Quintana Roo, Mexico. Point counts were used to quantify the avifauna by habitat, and Shannon´s and Simpson´s diversity index were used to determine bird diversity. Additionally, bird species were classified according to seasonality and trophic guild by type of habitat. A total of 160 species and 50 families was recorded, of which 100 species were permanent residents, 47 winter visitors and 11 transients. Mature tropical forest and tropical forest remnants had higher species richness than those of modified environments. This study supports the importance of tropical forest remnants as shelters for bird species in landscapes with tourism developments, and the relevance of these remnants to maintaining high bird diversity.

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.
