Forest is the most significant habitat for birds by supporting around 75% of all bird species while only 45% of all bird species have adapted to humans modified habitats. The research was conducted in the Montane Forest Research Station, Jos, Plateau State, in other to determine the abundance, diversity and effect of habitat types on bird’s species diversity. Fifteen transects of 200m were laid in the three habitat types (riparian forest, farmland and residential area) using stratified random sampling method. The data collected were analysed using R console. Shannon Weiner diversity index was used to analyse species diversity while generalized linear model was used to determine the effect of the habitat variables on bird species diversity. The result showed a total number of 1466 individual birds belonging to 17 families and 60 bird species were sighted. The abundance of birds was highest in riparian forest (2252), farmland (1732) and Residential area (1094) with no significance difference (p=0.177). Species richness was higher in the riparian forest (57), farmland (49), and the residential area (44). It also revealed that bird diversity index was highly significant. Riparian forest had the highest diversity (4.77), and the species were more evenly distributed (0.6) as compared to the other habitat types. The higher the number of trees and canopy cover the higher the diversity of species as was observed in the riparian forest where forest species that weren’t seen in the other habitats were found. The farmland and residential areas also hold a considerable number of some generalist bird species due to some patches of vegetation found in the habitat. Therefore, conservation efforts should be directed towards keeping vegetation intact in human dominated areas, as it serves as repository for bird species which are ecologically important. Hence, planting trees (economic, fruit and ornamental) should be encouraged.

Species Richness And Abundance

Background: Birds are one component of biodiversity. Ethiopia is rich in biodiversity resources. The avian diversity record is far from complete. There is no scientifically documented information on bird species composition and abundance at Nensebo forest. The objective of the study was to assess species composition, relative abundance and distribution of birds at Nensebo forest in southern Ethiopia. Methods: We employed a stratified random sampling technique with our study area stratified into two dominant habitat types: moist Afromontane forest and modified habitat. Within strata, we established 20 transect lines of 1km length and 0.25km width to sample 27.75% of the study area. We used line transect count methods aided by binoculars to estimate avian species diversity and distribution. We employed quantitative biodiversity indices, such as Shannon wiener diversity indexes to compare species diversity among habitat types and two way ANOVA to analyze the effect of season and habitat on bird species richness and abundance. Results: A total of 105 bird species consisting of 1 endemic, 8 near endemic, 1 globally threatened and 9 Palearctic migrants were recorded in Nensebo forest. Species richness and abundance varied between habitat types in Nensebo forest with mean species richness greater in modified habitat (mean= 4.70 ±1.65) as compared to moist Afromontane forest habitat (mean= 3.95 ±4.12, F=94.66 P<0.001). Additionally, modified habitat (Shannon diversity index= 4.131) harbored higher diversity of birds as opposed to Afromontane forest habitat (Shannon diversity index=3.79). Conclusion: The Nensebo forest has high avian species diversity including several endemic and endangered species revealing the importance of this site for bird conservation. Although we found that habitat heterogeneity favored bird species diversity, moist Afromontane habitat is critical for forest obligate species. Hence, sustainable bird conservation strategies including land use planning should be initiated for this area.

ADILI, A., KARTAWINATA, K., SOEDJITO, H. & SAMBAS, E. N. 2018. Tree species diversity in a pristine montane forest previously untouched by human activities in Foja Mountains, Papua, Indonesia. Reinwardtia 17(2): 133‒154. ‒‒ A study on structure and composition of the pristine montane forest previously untouched by human activities was conducted at the Foja Mountains in November 2008. We established a one-hectare plot divided into 100 subplots of 10 m × 10 m each. We enumerated all trees with DBH ≥ 10 cm which diameters were measured, heights were estimated and habitats were noted. We recorded 59 species, 42 genera and 27 families, comprising 693 trees with the total basal area (BA) of 41.35 m2/ha. The forest had lower species richness compared to those of lowland forests in Kalimantan, and Sumatra and montane forests in West Java. The Shannon-Wiener’s diversity index was 3.22. Nothofagus rubra (Importance Value, IV=47.89%) and Parinari corymbosa (IV=40.3%) were the dominant species, constituting the basis for designating the forest as the Nothofagus rubra - Parinari corymbosa association. To date, the dominance of N. rubra is unique to the Foja Mountains, as elsewhere in Papua the montane forests were dominated by N. pullei or other species. The species-area curve indicated a minimal area of 5000 m2. On the family level Fagaceae (IV=53.23%), Chrysobalanaceae (IV=40.53%) and Myristicaceae (IV=26.43%) were dominant. Verti-cally the forest consisted of four strata (A–D). In each stratum Nothofagus rubra, Platea latifolia, Parinari corymbosa and Myristica hollrungii were dominant. The diameter class distribution of Nothofagus rubra, Parinari corymbosa and Platea latifolia led us to assume that these species were regenerating well.

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.

Riparian forest inventory is essential in understanding the floristic biodiversity and provides necessary information on the growth trend and status of plant diversity along forest ecosystem, especially the riparian forests. This study was undertaken to assess the species diversity, growth status, and bio-volume of Taia riparian forest for community-based conservation intervention. In this study, we enumerated 602 individual trees, which comprised 49 species that belong to 37 genera in 25 families. In total, 14 rectangular plots of dimension 20 × 50 m2 were demarcated. All trees species within the sampled plots having diameter at breast height [Dbh] ≥7 cm were identified and height measured using the Haga altimeter, girth and measuring tape to determine the growth status. The result shows that 83% of the trees enumerated have [Dbh] that range from 7 to 30 cm, whereas 17% had [Dbh] greater than 30 cm. Funtumia africana and Trichilia heudelotii were the dominant species in almost all aspects in the study area. Meliaceae, Apocynaceae, and Mimosaceae were the dominant families with the highest species. The Shannon diversity index was 3.094, whereas the Simpson and Evenness diversity was 0.9303 and 0.4502, respectively. Other diversity indices estimated were Margalef 7.544, Equitability 0.7949, and Fisher_alpha 12.77. The overall biovolume was 283.05 m,3 with a total basal cover of 12.54 m2. Height and [Dbh] were not significantly correlated with the biovolume. Biotic pressure such as fuelwood collection, unsustainable charcoal production, pole harvesting, bushfires, and other traditional and cultural functions contributes greatly to the exploitation of the riparian forest. Therefore, urgent strategic conservation and protection measures should be adopted to prevent further degradation of forest ecosystems along river banks in the district and other ecologies in Sierra Leone.

IUPHHK-RE PT Ekosistem Khatulistiwa Lestari is the habitat of various wildlife species, comprises of a restoration forest area surrounded by production forest and oil palm plantations. The threats of damages from illegal logging and land clearing activities tend to threaten the wildlife existence. Therefore, this study aims to determine the distribution and diversity of bird species in PT Ekosistem Khatulistiwa Lestari. The study was conducted from  January - February 2019, and  data collection was conducted using the IPA (Index Ponctualle deAbondance) method. Furthermore, data analysis used diversity index, evenness index, and species similarity with dendrogram analysis using SPSS 21. The results showed that the highest bird species were found in mangroves (32 species), old swamp scrubs (26 species), young swamp scrubs (24 species), plantations (13 species), and settlement (15 species) habitats. Meanwhile, the diversity index of bird species in the five habitat types is classified as medium diversity. Species evenness with the highest value is settlement (E = 0.93). The dendrogram image of the settlement area showed bird species, which can be found in the other four habitats.   Keywords: diversity, bird distribution, West Borneo, dendrogram

Collection of data on avifaunal diversity is a crucial component for monitoring the effects of habitat changes on biodiversity. A rapid cross sectional survey to document common bird species present in Kabale municipality was conducted over a period of 3 months. Birds were categorized into families and the Shannon–Weaver (H') diversity index and the abundance of all the species was calculated. A total of 1770 bird individuals consisting of 67 species, 34 families were recorded, with an overall species diversity of 3.41. The Grey Crowned Crane (Balearica regulorum) an endangered species and the Woolly–necked Stork (Ciconia episcopus) a vulnerable species were among the species recorded. The relatively high diversity is probably attributed to the presence of trees on farmland areas within the municipality. This combination seems to provide various food sources or nesting and perching grounds for the birds. Information generated by this study will serve as a benchmark for monitoring of changes in species diversity and composition over time. In addition, the list of birds will be useful to residents of the area and the many ecotourists who visit Kabale town.

Abstract The Mandalika Special Economic Zone (SEZ) was designated as a tourist area in 2015. The development of the Mandalika area directly impacts the sustainability, diversity of species, especially birds that make mangroves their habitat. The study aims to investigate the value of bird species diversity in mangrove habitats as bioindicators. Furthermore, the research has been carried out for three months, from March to May 2021. Research data collection uses the roaming method, and data analysis uses bird community structure analysis (Diversity Index). In this study, 33 species of birds were found. Furthermore, it was found that six species of birds are protected wildlife. In addition, 16 are migratory birds, and 27 are Least Concern (LC) bird species; four species have Near Threatened (NT) status. Meanwhile, the Index of bird community structure is H’ 2.7, uniformity E 0.8, and dominance C 0.9. The value of the bird community structure in the Mandalika SEZ shows the condition of mangrove habitat in the moderate damage category. Therefore, there needs to be an effort to preserve mangroves involving the community, government, and Indonesia Tourism Development Corporation (ITDC) area managers.
