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.

The trees of parks and gardens support many species, the survival of urban-dwelling species mainly bird species. Birds amongst other species provide a wide range of environmental and social functions to cities and urban dwellers. The present study aims to know bird diversity in two parks as bioindicator of automobile air pollution exposure, landscape changes and/or human interactions. The study areas were selected as per heavily-populated neighborhoods, nearby office buildings, nearby roads and continuous vehicular movements, human interactions as visitors, where high levels of human disturbance are common. The study was carried out at 2 sampling stations viz (i) Elliot park and (ii) Agri-horticulture Society. The bird species diversity was studied by qualitative and quantitative assessment. Indices were Species richness, Index of Dominance, Relative abundance, Shannon-Wiener Diversity Index and Evenness Index for birds for all selected sites were calculated using the statistical formulae. The present results as bioindicators bird species clearly indicate that the bird species are very few in numbers in both the parks. When comparison made between both the parks, it was observed less number of bird varieties (16 types) in Elliot park than varieties (9 types) more less in number in Agri-horticulture society. This study is a preliminary assessment of bird diversity but further researches are needed in relation to biochemical and genetic damage study as well as air pollution load by using instruments. In the present study it was concluded that the less numbers of birds and their different diversity indices were found a decreasing trends, though there no attempt has been made on physico-chemical properties of present air pollutants. The less number of varieties of bird species are as tolerant bioindicators, which may be due to the vehicular pollution and/or human interference and/or landscape changes due to nearby neighborhood blocks, office and residential buildings, continuous movement of vehicles etc

Forest Remnants

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.

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.
