The grasslands of Nepal's Terai are extremely rich in bird species with several globally threatened species. These birds are often quite sensitive to changes in the habitat quality and microclimate around them making them ideal indicators of the grassland ecosystem health. Unfortunately, very little is known about the grassland avifauna. This study was conducted to determine the avifaunal composition and diversity with respect to the vegetation height and patch openness in the grasslands of Shuklaphanta Wildlife Reserve by using open width line transect method along fire-lines. The birds and the vegetation were recorded using BBIRD protocol and the species diversity was calculated. The Kruskal-Walli test for differences in median populations and Canonical Correspondence Analysis (CCA) were also conducted. This study recorded 104 species birds belonging to 39 families among which 29 species were insectivorous, 17 herbivorous, 17 carnivorous and the rest omnivorous with 94 resident species and 10 summer visitor species. Covered patches of short grassland had highest number of species while covered patches of tall grasslands had the highest species diversity. The results from KruskallWallis test and CCA highlighted the need for the maintenance of ecological integrity of all the grassland habitat areas.

The line transect method has been employed to assess species diversity, population densities and community structure of birds breeding in a mosaic of Kalahari Woodland and farmland, NE Namibia. The transect, 4.5 km long, was surveyed in 2014 and 2015. The total annual rainfall in 2014 was much higher than in 2015 (427 mm vs. 262 mm). In total, 40 breeding species in 2014, and 46 in 2015 were recorded. Six species were dominant in 2014 (Cape Turtle Dove, Laughing Dove, Emerald-spotted Dove, Blue Waxbill, and White-browed Scrub Robin) and only three species in 2015 (Cape Turtle Dove and Blue Waxbill and Yellow-fronted Canary). Although the cumulative dominance in 2014 almost doubled that in 2015, the Community Index in both years was almost identical. Also diversity indices and evenness index were very similar in both years compared. Granivorous birds were the most numerous feeding guild. Their contribution was similar in 2014 and 2015 (46.7 % vs. 43.4 %). Two other feeding guilds, insectivores and frugivores, comprised together more than 50 % in both years. The number of bird species and species diversity were not influenced by the differential rainfall. However, contrary to expectations, population densities of most bird species (at least the more numerous ones) were higher in the year with lower than in the year with higher rainfall. The number of species and species diversity was similar in the farmland and in neighbouring Kalahari Woodland in a pristine stage. However, population densities of most species were lower in the farmland than in the pristine woodland.

ABSTRACTPatterns of bird species diversity within three vegetation types were investigated by the line transect method on Mundanthurai Plateau, South India. Minimum numbers of species and individuals were seen in the study area during July and August. Such seasonal variation was more pronounced in riverine and dry deciduous forest than in the secondary vegetation which was avoided by most of the winter migrants. There was a greater species overlap between riverine and dry deciduous forest than between riverine and secondary vegetation.No relationship could be established between bird species diversity and tree species/foliage height diversity. The secondary vegetation had fewer specialized forest species and more generalists. Larger birds (>200 g) were rare but smaller ones (<50 g) were more common. The paper emphasizes that the conservation status of avifauna in managed forests in India needs to be assessed and monitored.

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.

One of the animals that are easy to find is a bird. Based on data about the increase in the number of bird species, it can be ascertained that these animals can be found in every region in Indonesia, with diverse species and even species that are endemic to a certain area. West Papua is one of the regions in Indonesia which is rich in various species of birds, including Cendrawasih which can also be found in the Natural Forest of Malagufuk Village, Klayili District, Sorong Regency. Based on information from the surrounding community, several types of Cendrawasih are often seen in the natural forests of Malagufuk Village, but their diversity and population are not known with certainty. This study aims to determine the diversity of species and population of Cendrawasih birds in the natural forest of Malagufuk Village, Klayili District, Sorong Regency, West Papua. Thus, the results of this study are expected to be a source of data in the context of preserving and protecting the existing Cendrawasih species. Data collection on the species composition and population of Cendrawasih was carried out using the Line Transect method by making 10 observation lines with a line length of 500 m each and a distance between lines of 100 m. The results showed that there were found 3 spesies of Cendrawasih with estimated populations and densities as follows: Cendrawasih Kuning Kecil (Paradisaea minor) had an estimated population of 7.48 individuals with a density of 2.93 individuals / ha; Cendrawasih Raja (Cicinnurus regius) has an estimated population of 5 individuals with a density of 1.67 individuals / ha; and Toowa Cemerlang (Ptiloris magnificus) had an estimated population of 2.22 individuals with a density of 0.74 individuals / ha. When the research was carried out, it was seen that the three types of Cendrawasih used several types of trees as places for activities (playing or dancing), namely Matoa (Pometia coreacea), Merbau (Intsia bijuga), Damar (Agathis dammara). Beringin (Ficus benjamina), and Pala hutan (Myristica sp) with tree heights above 20 m.

Tha-kha Floating Market is a famous tourist attraction in Tha Kha sub-district, Amphawa district, Samut Songkram Province, Thailand. There are Thai paddle-boats for tourists to get close to nature and local people lifestyle along the canals. The objectives of this research were (1) to study species diversity, feeding behavior and status of birds in the research area. (2) to analyze abundance and similarity of birds in the research area. The data was carried out by field survey of species of birds and their behaviors sighted directly and from their calls by using line transect method then classify species, feeding behavior and status of birds, analyze their abundance and similarity in three routes. Three boat touring routes were surveyed; route 1 (Tha Kha floating market—homestay), route 2 (Tha Kha floating market—Thai traditional sugar making kiln), and route 3 (Thai traditional sugar making kiln—resort). The survey was conducted in the morning from 7 a.m. to 10 a.m. and in the afternoon from 3 p.m. to 6 p.m. One survey was made each month from April 2017–March 2018. The result of this research found that there were 15 orders, 37 families and 74 species of birds. The highest number of bird species in 3 routes was 49 species in December and 47 species in November accordingly because it was migratory season of migratory birds in the research area. According to bird feeding behavior, the maximum insectivorous bird species of 35 were found in 3 routes. According to status of birds, 52 resident birds, 9 migratory birds, 13 resident and migratory birds were found in 3 routes. According to bird abundance, 21 bird species were in level 5, 7 bird species in level 4, 20 bird species in level 3, 9 bird species in level 2 and 17 bird species in level 1. According to bird similarity index, the similarity index between route 1 and route 3 was 0.814. The community also organized eco-touring activities by using Thai paddle-boats. So the birds are as indicators of natural balance of local ecosystem.

  Birds are important bio-indicators and provide various ecosystem services including pollination, dispersal, and pest control. However, they are threatened by habitat loss, fragmentation, and degradation. Study on species diversity, relative abundance, and habitat associations of avifauna were conducted in Tara Gedam Monastery forest patch and associated habitats from July 2016 to April 2017. Stratified random sampling approach was used to classify habitats and select sampling plots based on vegetation type. Consequently, forest, bushland, farmland, and plantation habitats were used for data collection. Point count and line transect methods were used to collect data, and Shannon-Weiner and Simpson’s diversity indices were used to estimate the avian species diversity. One-way ANOVA was conducted to compare avian relative abundance and richness among the different habitat types. A total of 98 species of birds belonging to 14 orders and 41 families were recorded in Tara Gedam Monastery forest and associated habitats. Eighty-seven resident bird species and eleven Palearctic migrants were identified of which seven species are endemic to Ethiopia and Eritrea. The highest avian diversity (H’=4.23) was recorded in the study area during the wet season.The highest species similarity index (SI=0.47) was recorded between forest and bushland habitats during the wet season, while the lowest similarity index (SI=0.07) was found between bush-land and farmland habitats during the dry season. Species richness and relative abundance of bird species varied between the wet and dry seasons. Besides birds, Tara Gedam Monastery forest supports a large number of other wild fauna species, which indicates the area’s potential to support biodiversity. Therefore, there must be a collaborative work between the monastery and different governmental and non-governmental organizations to protect the entire ecosystem in order to conserve the whole biodiversity of the area in general and the avifauna in particular.

Abstract. Suharno, Kadir A, Sembiring E, Masiki AD, Mubarak T, Lessil N, Ratnawati LD, Idris D, Imbenai JG. 2021. Population estimation of freshwater crocodiles (Crocodylus novaeguineae) and tree vegetation diversity at wildlife reserve of Mamberamo Foja, Papua, Indonesia. Biodiversitas 22: 2928-2936. The structure and composition of vegetation in the conservation area have a major influence on the existence of other flora and fauna, including freshwater crocodiles (C. novaeguineae). Wildlife Reserve of Mamberamo Foja (WRMF) is a conservation area in Papua that aims to protect the habitat and existence of freshwater crocodiles. The purpose of this study was to estimate the number of freshwater crocodile populations and tree species diversity in the WRMF, Papua. The method used was a field survey. The crocodile survey was carried out using the spotlight night count method. Tree species diversity was assessed using the line-transect plot method in 6 different locations representing the Upper, Central, and Lower Mamberamo. The results of the investigation showed that the freshwater crocodile population in the WRMF was around 0.3-19.7 individuals per kilometer. The population of this freshwater crocodile was very high, with an average of 4.5 individuals per 1-kilometer distance. The highest population numbers were found in the upstream Mamberamo River area 6.22 ind./km, followed by the central Mamberamo (2.21 ind./km) and downstream Mamberamo area (2.05 ind./km). Crocodiles were found in the Mamberamo River and other river systems, such as swamps and lakes. The tree vegetation in this area is still relatively good, and there are 112 species, dominated by the Moraceae, Burseraceae, Myrtaceae, Rubiaceae, Lauraceae, Dipterocarpaceae, and Euphorbiaceae families. The results of this study are important as a basis for determining the conservation policy for freshwater crocodiles that have limited distribution.
