A baseline study on diversity of birds in Sani Bheri River Valley, Nepal

Rivers and lakes are important habitats for both resident and migratory wetland-dependent birds. This paper presents the study of birds’ seasonal diversity in Sani Bheri River Valley, outside the protected areas of Nepal. The study was carried out from 8-17 March 2019 (Spring) and 12-21 October (Autumn) 2019 covering a 52 km river stretch from Naighat (upstream area where Pelma River and Uttarganga River mix and flow as Sani Bheri river) to Remnaghat (downstream towards the confluence with Thuli Bheri) using the Mackinnon Listing method. The present study recorded 851 occurrences belonging to 11 Orders, 33 Families, and 71 bird species. Order Passeriformes (52 species) and family Muscicapidae (13 species) were dominant. Plumbeous Water-redstart (Phoenicurus fuliginosus) had the highest relative abundance (7.64%). Shannon-Weiner diversity index (H’= 3.61) and Evenness index (e= 0.85) indicate the diverse assemblage of avian fauna in the study area. This study showed that Sani Bheri River Valley provides the habitat for one globally threatened, four nationally threatened, and eight species listed in Appendix-II of CITES. The results provide the baseline information on avian species, which can provide a good database and can be incorporated in conservation implications.

Birds are important components of biodiversity and acts as an indicator of habitat quality, productivity and stability. This study aimed to document species richness and assess the temporal distribution pattern of globally threatened bird species in the Basanta Protected Forest (BPF), one of the largest corridor forests which connects Dudhwa National Park (India) with protected areas of western lowland Nepal. During study period of ten years from 2010 to 2019, a total of 381 bird species from 78 families of 19 orders were recorded. Order Passeriformes had the highest species richness (n=180) followed by order Accipitriformes and Charadriiformes. Among the families, the family Muscicapidae had the highest species richness (n=31), followed by Accipitridae and Anatidae. Majority of bird recorded were forest bird followed by wetland and farmland bird species. Fifteen globally threatened species like red-headed vulture (Sarcogyps calvus), white-rumped vulture (Gyps bengalensis), slender-billed vulture (Gyps tenuirostris), steppe eagle (Aquila nipalensis) and Egyptian vulture (Neophron percnopterus) were recorded in the BPF. Extensive avian survey in the BPF is important for further exploration of avian community along with its driving factors, which might play a crucial role in developing baseline information and implementing conservation implications.

Nagarjun forest of Shivapuri Nagarjun National Park plays a significant role in the conservation of avifaunal diversity, but there are very few studies on birds of such local biodiversity hotspots in Nepal. The objective of the present study was to obtain information on seasonal diversity, species richness and relative abundance of birds in Nagarjun forest. The study was carried out from August 2019to June 2020 covering two seasons (autumn and spring). A total of 97 species of birds belonging to 10 orders and 42 families were recorded from three trails. Total22 Mackinnon’s lists were produced resulting 97 bird species recorded from entire field survey. Passeriformes was recorded as the most dominating order represented by 69 species. Mackinnon’s listing and direct observation methods were used to survey birds and Shannon-Weiner diversity index was used for data analysis. Relative abundance showed that most of the species were rare (54%) followed by uncommon (20%), very common (15%) and common (11%). Shannon-Weiner diversity index showed higher value for spring (H = 3.895) than autumn (H =3.807) and evenness was also higher in spring (E= 0.899) than autumn (E = 0.887).The result indicated higher species richness in spring with 76 species than autumn with 73 species. Based on the Shannon–Weiner index, the overall species diversity was highest in the trail III.

Bird Species Diversity

The diversity of bird species can reflect the high biodiversity of an area. it means that birds can be used as a bio-indicator of environmental quality. Determining the quality and level ofenvironmental damage can be seen from the diversity of bird species in the region. Environmental quality will be better if the diversity of bird species in the region is diverse.Birds have an important role in protecting the ecosystem in the Liwa Botanical Garden. The presence of birds in the Liwa Botanical Garden has not been well identified. Therefore thisresearch needs to be done. This research was conducted on 12 October 2019 to 20 October 2019 in the Liwa Botanical Garden, West Lampung. Data collection of bird species isconducted in the morning at 06.30.00-08.30 West Indonesia Time and afternoon at 16.30-18.00 West Indonesia Time, with a combination of the count point and the transect method then all encounters with birds are recorded and identified directly at the study site. After the birds are identified, data is processed to find out Shannon's level index and diversity index. The species diversity index uses the Shannon and Weiner formula. The level of diversity is determined based on the species diversity index. The results showed that there were 15 bird species with a total of 466 individuals with a moderate diversity index and an evenness index indicating a distressed community.

Malaise Traps

A study on abundance and diversity of Hymenoptera was conducted in Gunung Datuk, Rembau. Samplings were conducted from November 2014 to February 2015 using six Malaise traps. Three traps were placed at Site 1 at 700m height for high elevation and the remaining traps were placed at Site 2 at 200m height for low elevation. A total number of 221 Hymenopteran were collected which consist of nine families namely Ichneumonidae, Formicidae, Braconidae, Bethylidae, Evaniidae, Tiphiidae, Vespidae, Pompilidae and Apidae. In this study, 93 individuals were obtained from Site 1, comprising nine families and 43 morphospecies while 127 individuals were obtained from Site 2 with nine families and 45 morphospecies. Formicidae was the most dominant family collected from both sites with a total of 104 individuals while the least family recorded was Apidae with only one individual. Shannon’s Weiner Diversity Index (H’) showed Site 1 had the higher diversity value with H’ = 3.17 compared to Site 2 with value H’ = 3.12. For Evenness Index, Site 1 had higher value compared to Site 2 with E’ = 0.84 and E’ = 0.82 respectively. Moreover, for Margalef Richness Index, Site 1 recorded R’ = 9.24 while site two recorded R’ = 9.08 which concluded that Site 1 had higher species richness compared to Site 2. Paired t-test showed that both sites had no significant difference with p>0.05. Overall study showed that the diversity and abundance of Hymenoptera in Gunung Datuk were low since the value of H’ is less than 3.50.

Rarefaction Analysis

AbstractIn the Indian subcontinent there is hardly any study that compares the bird community structure of urban/suburban areas with those of forest habitat. The present survey identified diverse assemblages of birds in the Pauri district at different elevations. A total of 125 bird species belonging to 40 families including two least count species (Lophura leucomelanos and Pucrasia marcolopha) were recorded during this survey in the forest and urbanized habitats of Pauri District (Garhwal Hiamalaya) of Uttarakhand state, India. The high elevation (Pauri 1600–2100 m a.s.l.), mid elevation (Srikot-Khanda 900–1300 m a.s.l.) and low elevation (Srinagar 500–900 m a.s.l.) contributed 88.8%, 63.2% and 58.4% of the total species respectively. Rarefaction analysis and Shannon diversity index showed that the high elevation forest habitat had highest bird species richness (BSR) and bird species diversity (BSD) followed by the mid and then the low elevation forests. BSR and BSD fluctuated across seasons at all elevations but not across habitat types. Present study provides a base line data about avian community composition in urbanized and natural habitats along altitudinal gradient in the study area. This information may be useful to the conservation biologists for the better management and conservation of the avifauna in the Western Himalaya, a part of one of the hot biodiversity spots of the world.

Wiener Diversity Index

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.
