KEANEKARAGAMAN FAUNA DI TAMAN KEANEKARAGAMAN HAYATI CILEGON PT. CHANDRA ASRI

The establishment of Taman Kehati Asri by PT Chandra Asri is a form of protection of biodiversity to improve the quality of biodiversity, including fauna. The existence of fauna is very important in ecosystem activities because fauna is a consumer in the food pyramid. If a population decreases, it will have a negative impact on the continuity of food webs and hinder the flow of energy cycle. This study aimed to identify the diversity of fauna in the Taman Kehati Asri area of PT. Chandra Asri Petrochemical, in Gunung Sugih Village, Ciwandan District, Cilegon City, Banten. The research was conducted in October 2022. The methods used were point count and cruise method. Based on the research results, it was found that there were 37 species of fauna belonging to 4 classes, namely birds, mammals, herpetofauna and insects. The result of total species diversity index was 2.98 which was categorized as in the medium category. Furthermore, the fauna dominance index was 0.075 which indicated that one or several species of fauna were not dominated in that area.

Bird diversity and mangrove forest as potential ecotourism destinations in Kapo-kapo Bay, Cubadak Island, West Sumatra, Indonesia

Abstract. Novarino W, Mukhtar E, Putri AS, Anggraini PL. 2023. Bird diversity and mangrove forest as potential ecotourism destinations in Kapo-kapo Bay, Cubadak Island, West Sumatra, Indonesia. Biodiversitas 24: 3583-3591. Mangrove forests play an important role in the management of the coastal ecosystem of Indonesia. Research on bird diversity has been carried out to support ecotourism attractions in the mangrove area of Kapo-kapo Bay, West Sumatra. The objective of this study is to determine the bird diversity and mangrove plant diversity in the mangrove kapo-kapo Bay area, West Sumatra, using the point count method and transect method. Mangrove plants have been found in three families, five genera, and six species. The vegetation composition on this research site is lower than that on Sumatra's east coast. The composition of mangrove trees and tree diversity was lower on the west coast of Sumatra than on the east coast. The composition and diversity of birds at the study sites were not significantly different between the mangrove forests on Sumatra's west and east coasts. Rhizophora apiculata Blume species dominate the mangrove forests in Kapo-kapo Bay, while Collocalia esculenta species dominate the birds. The analysis of the suitability of mangrove ecotourism in Kapo-kapo Bay obtained a score of 111 or 92.5%, placing it in the Very Suitable category (S1) to be developed as an ecotourism area. The presence of birds and bird habitat use in mangroves are all interesting ecotourism attractions.

Species richness, population, sex ratio and activities of hornbills inhabiting patches of forests in an oil palm plantation concession in Penajam Paser Utara, East Kalimantan

Well-maintained oil palm concessions with patches of natural ecosystems can be a home for Hornbills. This paper is mainly focused to evaluate the species richness and activities of the hornbill community inhabiting patches of forest in oil palm plantations in Penajam Paser Utara, East Kalimantan. The ecological observation was focused on the largest forest patches, a total of 1 432 Ha. The data collected included species inventory and behavioral activities of hornbills. Hornbill activities were observed from 45 observation stations using the fixed radius point count method. Vegetation data were collected using a single plot method in 52 stations. Based on the vegetation survey, the number of plant species found was 151 species from 53 plant families. Dominant families are Moraceae and Euphorbiaceae with 14 species. The forest patches are used for foraging sites by hornbills, they fed on Ficus benjamina (Moraceae) and Ficus sp. (Moraceae). The favorite tree for roosting is Kompasia excelsa because the tree is around the Ficus benjamina and is an Emergent tree. Our results show that remnants of forest patches on oil palm plantations can provide spaces for hornbills’ activities which supports the sustainability of hornbills in the region.

Bird community to be developed for birdwatching in Buperta Cibubur Urban Forest, Jakarta

The urban forest of Buperta Cibubur as a recreational and educational site can be developed for birdwatching. This study aims to identify the bird species in four tracks (ranging from 1.9-2.9 km across the built area, open area, 2 tracks in the sparse forest, and thick forest), and provide recommendations (tracks, timing, potential species found) for birdwatching activity. Bird data was collected in March-April 2022, using the standard point count method (replicated three times), in the early morning and late afternoon, totaling 90 observation hours. There were 39 species from 25 families found in all tracks. The thick forest and the built area had the highest number of species (both 27 species). The built area also had the highest bird abundance (1098 individuals). Meanwhile, sparse forest#2 had the least species (19). Some birds were common in all tracks, including Sooty-headed Bulbul, Scarlet-headed Flowerpecker, and Small Minivet. Other attractive and rare species found in the thick forest were the Blue-eared Kingfisher and Javan Blue-flycatcher. The most effective time to conduct birdwatching is suggested at 6-7 am and 4:30-5:30 pm, especially in built areas, forests, and open area tracks. As birdwatching is relatively new in Jakarta, while Buperta has a diverse bird species in the urban area, we recommend developing a birdwatching activity in Buperta.

Spruce- and beech-dominated primary forests in the western Carpathians differ in terms of forest structure and bird assemblages, independently of disturbance regimes

Mountain spruce- and beech-dominated forests (SDPF and BDPF) are of major importance in temperate Europe. However, information on the differences between their historical disturbance regimes, structures, and biodiversity is still incomplete. To address this knowledge gap, we established 118 circular research plots across 18 primary forest stands. We analysed the disturbance history of the last 250 years by dendrochronological methods and calculated disturbance frequency, severity, and timing. We also measured forest structure (DBH, tree density, volume of deadwood, and other parameters). Breeding bird populations were examined by point count method during the spring seasons 2017–2018 (SDPF) and 2019–2020 (BDPF). Using direct ordination analysis, we compared the disturbance history, structure and bird assemblage in both forest types. While no differences were found regarding disturbance regimes between forest types, forest structure and bird assemblages were significantly different. SDPF had a significantly higher density of cavities and higher canopy openness, while higher tree species richness and more intense regeneration was found in BDPF. Bird assemblage showed higher species richness in BDPF, but lower total abundance. Most bird species which occurred in both forest types were more numerous in spruce-dominated forests, but more species occurred exclusively in BDPF. Further, some SDPF- preferring species were found in naturally disturbed patches in BDPF. We conclude that although natural disturbances are important drivers of primary forest structures, differences in the bird assemblages in the explored primary forest types were largely independent of disturbance regimes.

STUDI KEPADATAN POPULASI BURUNG ENDEMIK TIMOR DI SEPANJANG JALUR PATROLI DESA FATUMNASI, CAGAR ALAM MUTIS, KABUPATEN TIMOR TENGAH SELATAN, PROVINSI NUSA TENGGARA TIMUR

Birds are wild animals that play an important role in building the food chain, helping pollination, controlling insect pest populations, and seed dispersal agents that are useful for natural forest regeneration. An animal is said to be endemic if the species is a native species that can only be found in one place and not found in other places or areas as well as Endemic Birds that will be studied in the Mutis Nature Reserve Area. This study was conducted to determine the population density of Timor endemic birds along the Patrol Route to Padang I, Fatumnasi Village, Mutis Nature Reserve, South Central Timor Regency, East Nusa Tenggara Province. This research was conducted from April to May 2022. Data collection on the Population Density of Timor's Endemic Birds used the Point Count method. Bird population density data analysis used the Krebs formula and the Eisenberg formula. The results of this study recorded that 6 species of birds with the highest population density were Myzomela Timor (0.72 ind/ha), Timor Honeysucker (0.61 ind/ha), Timor Pergam (0.55 ind/ha), Opior Timor (0.50 ind/ha) and the lowest population density or the least in the Timor Kancilan (0.24 ind/ha) and Timor Anis (0.38 ind/ha). Over time, population density will decrease or increase according to the resilience of adaptation to changes in environmental conditions and competition with other organisms.

Biology Learning Content Analysis on Aves Diversity: A Case Study at Kaduberureum Biodiversity Park’s PT Chandra Asri Petrochemical Tbk, Indonesia

Biology learning must be delivered contextually, for example, by presenting content based on field facts related to biodiversity. One of the biodiversity conservation areas in Banten Province is Kadubeureum Biodiversity Park, as a form of PT Chandra Asri's contribution to environmental conservation. The biodiversity park acts as a protected area for flora and fauna species found in the area, including Aves. The existence of Aves affects the quality of an environment because Aves are an important component of the ecosystem. This study aims to analyze biology content based on Aves diversity in the Kadubeureum Biodiversity Park to be implemented as contextual learning material, especially in the biodiversity concept. The research was conducted in July-November 2022. The method used was a survey and case study, completed with the point count method for Aves data collection in Biodiversity Park’s PT Chandra Asri at Kadubeureum Village, Serang, Banten, Indonesia. Based on the research identified 28 species of Aves including to 17 families. The results showed that there were several species of Aves endemic to Java, such as the "Javan Bondol" (Lonchura leucogastroides), the "Mountain Pijantung" (Arachnothera affinis), the "Paok Pancawarna" (Hydrornis guajanus), and the "Java Cinenen" (Orthotomus sepium). Furthermore, the facts obtained based on the Aves diversity observation can be used as contextual biology learning content, in the concept of biodiversity, such as for classification, biodiversity level, as well as threats and conservation effort learning.

Bird composition as an environmental quality indicator in Wallacea’s urban area

North Sulawesi Province, part of Wallace Bioregion, has a complex ecosystem. Advanced urban development brings various impacts, such as environmental change. Birds’ existence around human provides some advantages, such as assisting the process of plant pollination, controlling insect populations, and indicators of environmental quality. This study aimed to determine the bird species composition in four locations and the environmental quality was analysed using the Bird Community Index (BCI). This study gathered data on bird species in Manado Bay, Gunung Tumpa, Kawanua Arboretum, and the Kaki Dian areas. We conducted field observation through point count method as primary data and the secondary data were obtained from previous publications. Data were analyzed using Bird Community and Sorenson indexes. This study revealed that the birds’ quantities and composition moderately varied in four locations. This study found 37 bird species in Manado Bay, 33 in Tumpa Mountain, 36 in Kawanua Arboretum, and 49 in the Klabat mountain areas. The Bird Community Index (BCI) accumulation ranged from 56.0 – 68.4 and it was categorized as medium environmental quality. Sorensen’s community similarity index displayed a value of 30.3-51.0% which classified as low to medium community similarity.

Diversity, composition and conservation status of avian fauna in the forest and the wetland sites of Hastinapur wildlife sanctuary, India

Almost, in all flora and fauna, the species richness is affected by environmental changes; hence it is important to survey regularly to understand the current composition and diversity of different wildlife species in an ecosystem. The present study surveyed to assess the species distribution, conservation status, abundance and diversity of birds using the point count method, at two different habitats, a wetland (BhikundJheel; BJ) and a forest (Arjun Van; AV) in Hastinapur wildlife sanctuary, India. We surveyed early in the morning (before and after sunrise) and evening (before sunset) for 20 min at every point from January 2019 to April 2019. A total of 96 bird species were recorded, which belong to the 40 families and 15 orders. Out of 96 species, we recorded 67 resident bird species and 29 migratory bird species. The number of bird species specific to the type of habitat was higher in BhikundJheel than those in Arjun Van. The species richness and abundance were higher in the wetland (81; 5605)than in the forest habitat(45; 1716); however, evenness (J’) and diversity [Shannon-Weiner (H’) and Simpson diversity (D)]indices were higher in the forest habitat (J’: 0.827, H’: 3.420, D: 0.960) than in the wetland habitat (J’: 0.669, H’: 2.940, D: 0.827). Overall, we found that in the wetland habitats had more species richness than in the forests.

Bird Diversity in Paddy Field Habitats During The Paddy Ripening Phase (Oryza sativa L.) Jurong Peujeura Village, Aceh Besar Regency, Indonesia

Birds are organisms that can be found in a variety of habitats. One of the bird habitats is paddy fields. Birds found in paddy fields generally carry out activities such as foraging, breeding, and competing. This study aims to determine the diversity of birds in paddy field habitats during the paddy ripening phase (Oryza sativa L.). The study was conducted from April to June 2022. The location of the study was Jurong Peujera Village, Ingin Jaya District, Aceh Besar Regency. This study used the Point Count method with a radius of 50 m and a distance between points of 150 m. Observations were made at 9 observation points with 4 repetitions, in which the duration of observations was 10 minutes at each observation point. The observation was conducted in the morning and evening at 06.30-10.00 AM and 03.30-05.00 PM. The results obtained were 2586 bird individuals consisting of 14 species from 11 families. The species with the highest number of individuals are Lonchura punctulata with 1535 individuals and Bubulcus ibis with 637 individuals. The highest percentage of families by species is Ardeidae (22%), and Estrildidae (15%). The Shannon-Wiener bird species diversity index in the paddy field area during paddy ripening phase was obtained H'=1.24 which indicates the level of diversity of the bird species is moderate. Meanwhile, based on the dominance index, Simpson shows a value of C=0.42 which indicates a low bird dominance level. The low level of bird dominance is due to the moderate diversity of species in the paddy field area.

Keanekaragaman Burung di Kawasan Babakan Siliwangi City Forest Path, Kota Bandung

Indonesia is a habitat for around 17% of the world’s bird species. Birds have an essential role, such as helping in pollination and seed dispersal, controlling insects, and as indicators of environmental change, hence their existence needs to be maintained to maintain the balance of the ecosystem. Babakan Siliwangi City Forest Path Bandung is an urban and green open area used as a public area allowing it to be a habitat for various birds. Therefore, this study aimed to determine the diversity and birds at that location. The method used in this study is the point count method with ten observation points and five repetitions with one observation line. The results showed five species of birds with 45 individuals from four families, namely Passeridae, Apodidae, Pycnonotidae, and Dicruridae. The index value of bird species diversity in this area is moderate (1.20). The Cucak Kutilang (Pycnonotus aurigaster) had the highest abundance of bird species (58%), while the lowest was the Srigunting (Dicrurus macrocercus) (2%). In addition, the evenness of bird species is high (0.74) with no dominance (0.39) and low species richness (1.05). Thus, the Babakan Siliwangi City Forest Path Bandung area has ecosystem conditions to support a bird’s habitat.

A study of avian diversity in Durgapur Government College Campus, West Bengal, India

The present study was performed to investigate bird diversity at Durgapur Government College Campus, West Bengal, India from January 2013 to January 2020. The standard point count method and opportunistic sightings were used to make the checklist of the bird species. A total of 106 different bird species belonging to 47 families were recorded. Sylviidae was recorded as the most diverse family. Out of the 106 bird species, 23 were winter migrants, 4 were summer migrants, 1 was passage migrant, 1 was vagrant and the rest 77 were residents. Winter months supported the highest species richness while maximum bird density was recorded in the month of March. The global population trend chart of the observed bird species showed that most of the species belonged to the stable category (52 %, 55 species). Alexandrine Parakeet (Psittacula eupatria) belonged to the Near Threatened category of the IUCN Red List category among the recorded birds. The present study area is now facing various anthropogenic disturbances which are leading to the decline of the bird populations and need special attention. More extensive studies will surely enrich our knowledge of the avifauna of this area.

Comparison of bird assemblage structures and diversity patterns between seasons among two Ethiopian wetlands

Wetlands are significant habitats for bird populations, and knowledge of the diversity and other ecological aspects of bird species contribute to the management of the ecosystem. The present study was based on comparative studies of the diversity and relative abundance of bird species in the two wetlands of southwest Ethiopia. The point count method was utilized in this study. For the data analysis, the Shannon–Weaver diversity index, independent sample t-test, and similarity index were employed. A total of 36 bird species under 11 orders and 24 families were identified. The species diversity and relative abundance were higher in both wetlands during the wet season. The Loga wetland had the higher diversity (H’ = 3.089), whereas the lowest species diversity (H’ = 2.643) was recorded in the wetland of Hurri. During the dry season, the Loga wetland (H’ = 2.738) and the Hurri habitat (H’ = 2.283) had higher and lower diversity, respectively. Seasonal variations in bird species diversity are not statistically significant (p > 0.05). Although the two wetlands support several water birds, they have received no conservation attention from concerned bodies. Further follow-up studies over a long period will help determine species-specific conservation measures for wetland-dependent birds.

Abundance and diversity of waterbirds around the Begnas Lake of Pokhara Valley, Nepal

We studied the seasonal abundance and diversity of waterbirds around the Begnas lake of Pokhara Valley. The status of waterbirds in Begnas wetland is not documented so; we monitored the waterbirds using the point count method in 12 different plots around the lake and compared the seasonal abundance and diversity during the 2019 Summer and 2020 winter with 24 hours of observation in each plot. A total of 585 individuals of 25 waterbird species from 10 families were recorded during the study period. Among the recorded species two species were globally threatened and the remaining were the least concerned categories. The greater abundance of waterbirds was recorded during winter (t = -5.98, p < 0.001). The abundance of all feeding guilds was found higher during winter. Cattle egret was recorded with the greatest abundance (N = 85) and Relative abundance (RA = 14.52), it was followed by great cormorant (N = 57, RA = 9.74) and common pochard was the least abundant (N = 2, RA = 0.34). There was no seasonal variation in the Shannon Wiener index (H’) and species evenness however, the species richness was higher during winter (W = 16.5, p < 0.01). Distance to the forest, road, and settlement did not affect the abundance and diversity of waterbirds however, the abundance of insectivore birds was increased with the decrease of distance to croplands (t = -3.13, p < 0.05). The Begnas wetland was found with a lower abundance and diversity of waterbirds in comparison to the Phewa and other wetlands of the Terai region of Nepal. The lake water pollution, infrastructural development, anthropogenic activities, recreational activities, and infestation of invasive plants like water hyacinth were the main threats to the waterbirds around Begnas lake. An awareness program about the conservation of waterbirds and regular monitoring of waterbirds in Begnas was recommended.

Agroforestry orchards support greater butterfly diversity than monoculture plantations in the tropics

Large-scale deforestation in the tropics, triggered by logging and subsequent agricultural monoculture has a significant adverse impact on biodiversity due to habitat degradation. Here, we measured the diversity of butterfly species in three agricultural landscapes, agroforestry orchards, oil palm, and rubber tree plantations. Butterfly species were counted at 127 sampling points over the course of a year using the point count method. We found that agroforestry orchards supported a greater number of butterfly species (74 species) compared to rubber tree (61 species) and oil palm plantations (54 species) which were dominated by generalist (73%) followed by forest specialists (27%). We found no significant difference of butterfly species composition between agroforestry orchards and rubber tree plantation, with both habitats associated with more butterfly species compared to oil palm plantations. This indicates butterflies were able to persist better in certain agricultural landscapes. GLMMs suggested that tree height, undergrowth coverage and height, and elevation determined butterfly diversity. Butterfly species richness was also influenced by season and landscape-level variables such as proximity to forest, mean NDVI, and habitat. Understanding the factors that contributed to butterfly species richness in an agroecosystem, stakeholders should consider management practices to improve biodiversity conservation such as ground vegetation management and retaining adjacent forest areas to enhance butterfly species richness. Furthermore, our findings suggest that agroforestry system should be considered to enhance biodiversity in agricultural landscapes.

The study seeks to determine and compare avifauna distribution in Ardo-kola and Yorro local Government area of Taraba State. The habitats were divided into Open Habitat, Montane Forest and Plantation Habitat. Point count method was used to collect data on avifauna distribution. 11,772 avifauna species from 37 families and 65 species were recorded. High avifauna distribution was observed both in wet and dry seasons in Plantation habitat. Plantation habitat can serve as a refuge for avifauna species, hence, there is needs for conservation attention by the local authorities and Locals

KEANEKARAGAMAN JENIS BURUNG DI WILAYAH TAMAN KOTA SPATODEA DAN TABEBUYA, JAKARTA SELATAN

Urban parks in South Jakarta are the main component of green open spaces which act as habitat for birds in the cities. Aim of this study was to determine the diversity of bird species around the South Jakarta City Park. The research was conducted in October-November 2021 in the city parks of Spatodea and Tabebuya, South Jakarta. Bird data collection used the point count method, while plant data collection used an inventory system. Results showed that the Tabebuya Park location had 9 species of birds from 8 different families, while in Spatodea Park there were 8 bird species found. The Tabebuya City Park was found to have medium species diversity index value, medium evenness index value and low dominance value index. Spatodea city park had a low value index of species diversity, low evenness value index, and low dominance value index. The highest number of bird species obtained was 7 species in total. The results showed that the urban park area in South Jakarta had low to moderate range of bird species diversity. This could happen because birds in urban landscapes tended to be more sensitive to the presence of certain stratification of vegetation, especially tree stratification.

Relationship Between Bird Communities and Environmental Changes in Tandung Village, Tinambung District, Polewali Mandar Regency, West Sulawesi Province

Indonesia's coastal region is known for its richness and diverse natural resources. However, the region is experiencing a transformation from mangrove ecosystems to the traditional pond cultures. This was happening in West Sulawesi that could damage the ecosystem in the long term, especially for the bird community. This study aims to inventory bird species in the bird community on the coast of Tandung Village, Tinambung District, Polewali Mandar Regency, West Sulawesi Province. In addition, we also study the bird community structure, find out the correlation among the bird communities, and the environmental condition during the inventory. In this study, we used a fixed-radius point count method to record birds. Field guide titled Burung-burung Pulau Paparan Sunda dan Wallacea di Kepulauan Indonesia was used to identify the species of observed birds. The results showed that of the 27 species recorded, there are 5 species with a high relative abundance, such as Egretta garzetta, Himantopus leucocephalus, Actitis hypoleucos, Ardeola speciosa, and Calidris ruficollis. Only H. leucocephalus is identified as a protected bird by the Indonesian government, while Calidris ruficollis is protected internationally as its conservational status (Near Threatened). The diversity index is moderate level, but it is decreasing day by day of observation, followed by the dominance index, evenness, and species richness. A high correlation between the two bird communities with two adjacent days of observation indicates similarity composition of community structure with different temporal scales and similar spatial scales. The map of environmental conditions shows changing weather in the period of observation sequentially from bright sky to cloudy and heavy rain and back to the normal bright sky at the last period of observation. The response of the bird community to the condition was by flying away when the weather is cloudy and rainy so that may decrease the diversity.
