Abstract. Ramlah S, Santosa Y, Santoso N, Rushayati SB. 2021. The variation of bird diversity in various oil palm land cover in North Mamuju, West Sulawesi, Indonesia. Biodiversitas 22: 3068-3074. The development of oil palm plantations provides various positive impacts. On the other hand, this development is suspected to bring negative impacts on biodiversity, especially reducing bird species diversity. Based on the other research, well-managed oil palm plantations that maintain high conservation value areas have high species diversity. This study aimed to identify bird species diversity in different types of oil palm plantation land covers in North Mamuju. Data observation of bird species was performed using the transect method. There were 4 transects on each land cover. The results of this study showed that the young oil palm area had a high index of diversity and species richness. The high species diversity in the young palm area was caused by habitat variations. There was a water flow that provides more feed sources. The distance between the young oil palm area and secondary forest area affected the number of species, species richness and diversity of bird species. The category of insectivore guild which included aerial insectivores and insectivores was the dominant guild in all types of land cover, both in the number of species and the number of individual abundances.

The expansion of oil palm plantation has been claimed as a major driver of biodiversity loss in the tropics, including birds. To date, only a few studies have been conducted to document the variation of bird diversity in different land cover within oil palm plantation. Therefore, it is necessary to conduct the research to investigate the variation of bird diversity. The objective of this study to identify the diversity of bird in different land cover within oil palm plantation. The observation of bird diversity was done in young stand of oil palm, old stand of oil palm, smallholder oil palm and in secondary forest as high stock carbon as natural reference before converting in to oil palm. The survey was done in August 2017 in Central Kalimantan, Indonesia. Data of bird species were recorded by direct observation using transect method. To calculate the diversity value of birds at different land cover, we used Margalef Index (Dmg) and Comunity similarity (IS). The result showed that the number of species and species diversity was highest at high carbon stock area which the number of species was 25 species and Margalef Index was 5.99. The young stand of oil palm have the highest evenness index (0.93), while the highest similarity index was observed in old stand of oil palm and in smallholder oil palm. Our study concludes that the existence of high carbon stock areas within oil palm plantation had a positive influence in increasing bird diversity. From a conservation perspective, retaining of natural habitat such as high carbon stock within oil palm plantation is one strategy to conserve biodiversity.

The avian diversity of Oak mixed forest in Pauri Garhwal district of Uttarakhand was studied during October 2019 to March 2020. Two strands of oak mixed forest located at different sites at 29º 22’-29º 75’ North and 78º, 10’ -78º,80’ East (1750 masl) were selected. Regular field survey was carried out during the morning and evening hours at each site. A total of 63 species of birds belonging to 07 orders and 31 families were recorded. The average bird diversity index H ¯was 3.202. The species richness was observed around 7.27 and species evenness was 0.72. The highest number of species was recorded at Ransi Oak mixed forest (63) and lowest number of bird species were recorded in Teka Oak mixed forest (60).

The expansion of the oil palm plantation establishment has been arousing someaccusation regarding the loss of biodiversity especially on bird diversity. Hence, this study was conducted to compare the bird diversity between oil palm plantation and its origin land cover. The study was conducted on May 2018 in 2 oil palm plantation in the West Sulawesi and its origin land cover around the plantation area. The observation was done twice a day, in the morning and afternoon, with 3 repetitions. The data was then analyzed using richness index, Evenness index and also index similarity to identify the similarities of bird species similarity between land covers. The result show that the highest number of bird species was found in theoil palm plantation of the company 1 which also happen for the evenness and richness indices. While, the similarity index showed the value about 0.42-0.46. Overall, the land cover changes also causing a change in the bird species composition.

The study of bird species diversity and richness in Dagona-Waterfowl Sanctuary was carried out during the midst of both early wet and late dry seasons, to provide comprehensive data on wild birds. Dagona Sanctuary is located within the BadeNguru Wetland sector. It is one of the important bird areas marked for the conservation of avifauna species in sub-Sahara region, Nigeria. Line Transect method was used to carry out birds’ survey at three different lake sites, namely: Gatsu (site:1), Mariam (site: 2) and Oxbow (site: 3). The instruments used were GarminTM 12 Global Positioning System (GPS), a pair of binoculars for bird’s identification, a field guide test- book and a 1,000 meters tape-rule. The data were tested with the Kolmogorov- Smirnov method o determine distribution level and birds’ diversity was assessed using Shannon-Weiner Diversity Index, while parametric tests were applied for all data. The results showed that bird species diversity was normally distributed in all the sites, site 2 had the highest diversity (2.74) compared to site 1: (1.84) and site 3: (1.62). Likewise, bird species richness in the area was normally distributed and significantly different (P<0.05) among the three sites. Site 1 had the highest number of bird species richness (16.36) (Species diversity is different species of birds at the site, while species richness is referring to specific species population), compared to site 2: (14.32) and site 3: (11.51). It was observed that there is a significant relationship between vegetation density and bird species diversity, because as tree density increases, diversity of bird species decreases. Therefore, there is a significant relationship between vegetation density and bird species diversity. A total of 135 bird species in 40 families was recorded during the survey. Seventy-four percent were found in site1, sixty-three percent in site 2 and seventy-one percent in site 3. The majority of wetland birds observed during this study were resident (Ardeidae family), migratory (Accipitridae family) and palearctic species (Yellow Wagtail, Warblers, Northern Shoveler and Sandpipers). It can be concluded that wild birds are good indicators of environmental condition, revealing the state of the wetland. Some sites were more disturbed, as observed in site 1 and site 3. It was, however, recommended that regular monitoring of the sites should be carried out so as to control changes in the state of the wetland ecosystem.

SummaryBird species diversity is investigated in different habitat types on Ngazidja (Grand Comoro), Comoro Islands. Total bird diversity does not differ significantly among different forest types, but the proportion of endemic species, endemic subspecies and non-endemic species does. Both intact mature forests and pioneer forests on the slopes of Mount Karthala are important for the preservation of bird endemism. The forests on La Grille are poor in endemic species, but their bird species diversity is high thanks to non-endemics. Planting of Eucalyptus is useless for endemic birds. Humblotia flavirostris, Turdus bewsheri and Nesillas brevicaudata avoid logged forests, but Alectroenas sganzini is numerous in them. Foudia eminentissima is common in forests with bananas planted in the undergrowth.La diversité en espèces d'oiseaux est étudiée dans différents habitats à Ngazidja (Grande Comore), lies Comores. La diversité totale ne varie pas d'une manière significative parmi les différents types de forêt, mais la fraction due aux especès endémiques, aux sous-espèces endémiques et aux espèces non-endémiques varie. Aussi bien les forêts intactes et matures et les forêts jeunes sur lave sont importantes pour la préservation d'oiseaux endémiques sur les flancs du Mont Karthala. Les forêts à La Grille sont pauvres en oiseaux endémiques, mais leur diversité est grande, grace aux espèces non-endémiques. Les plantations d'Eucalyptus n'ont pas de valeur pour les oiseaux endémiques. Humblotia flavirostris, Turdus bewsheri et Nesillas brevicaudata évitent les forêts exploitées pour le bois, mais Alectroenas sganzini y est nombreux. Foudia eminentissima est commun dans les forêts plantées de bananiers sous les arbres.
