“…So, the size of the wetlands might have influenced the bird diversity. This finding is well supported by Sarkar et al (2013) who found similar results. This study also brings to the notice that though the medium and large sized wetlands in this area support sensitive species, the existence of the wetlands is itself in peril due to invasion of species like Eichhornia crassipes and anthropogenic activities such as fishing, land encroachment for fishing and agriculture, cattle grazing, fertilizer run-off, harvesting of Trapa natans, and urban development.…”

Nine unprotected wetlands of Ayodhya district, Uttar Pradesh, India were studied to assess the bird species composition and richness from March 2019 to February 2020 using point count method. A total of 105 species of birds belonging to 79 genera, distributed among 35 families and 12 orders were recorded. Passeriformes had the highest diversity with 25 species and 12 families. Anatidae was the most dominant family with 15 species, constituting 14.29% of the wetland bird community in the study area. These wetlands provided habitat for 62 residential species, 42 winter migrants and one vagrant. The carnivore guild was the most dominant with 46 species. The wetland sites under study were continuously used by humans mainly for land encroachment, fishing activities and livestock grazing apart from other minor uses. Out of the nine selected wetlands, three wetlands (˂2 ha) had very few bird species (≤3), therefore were excluded from further calculations. But the rest of the six selected wetlands (˃5 ha) provided habitat for 12 bird species of conservation importance (one Endangered species, five Vulnerable species, and six Near Threatened species) according to the IUCN Red list. These wetlands also supported 39 species of birds having a declining population trend globally. These findings highlight the role of medium and large-sized unprotected wetlands in providing critical habitat to the birds throughout the year in Ayodhya district. Future research must concentrate on understanding the key factors influencing the presence and absence of birds in such unprotected wetlands so that these wetlands can be managed effectively to secure the potential habitat of birds.

“…Therefore, the decrease in waterbird diversity after the construction of wetland parks in Dianchi might also be related to human disturbance. In addition, park roads (visitor corridors) fragmented the habitats of some waterbirds and reduced diversity (Sarkar et al 2014). Wetland parks (including area size and vegetation configuration) should therefore be designed to cater adequately for humans and wildlife.…”

“…To equalise sampling efforts in wetlands of different sizes, one transect was established for each 25ha of the shallow-water (i.e., up to 4m deep) area. Each sample was dried separately at 80 Macroinvertebrate samples were collected from small boats using standard 0.5mm mesh D-frame dip nets following DiFranco (2006) and Sarkar et al (2014). Each sweep was made through the water column for a distance of 1m.…”

“…Fish abundance was estimated using catch-effort method (Johnson 1965) deploying cast nets (mesh size 6mm; radius 1.5m; sampling area 2.4±0.2 m 2 ), as used by Sarkar et al (2014). During each census 30 random deployments (10 deployments each along the edge, midline length and midline breadth of the wetland) were made from country boats and the mean number of fish caught per deployment was used to measure fish density.…”

Population trends and community composition of migratory waterbirds in three emerging wetlands of global significance in southwestern Bengal, India

We studied the diversity, abundance and population trends in three flourishing wetlands of southern Bengal over 16 years. These wetlands constituted a major shift from the present scenario of overall wetland deterioration, including monotonous declines in important winter visitors prevailing in surrounding wetlands, especially in Tilpara Reservoir and Purulia Saheb Bandh Lake. All the three wetlands support rich waterbird diversity and almost all of them tend to exhibit consistently stable or increasing trends in their populations during the course of the study. The waterbird communities did not differ greatly during the study period and were tending to arrive at their equilibria. These wetlands consistently support strong waterbird food-bases, which may support rich diversity. Since, they have already been supporting increasing or stable populations of a majority of the important waterbird species they are expected to emerge as important waterbird abodes in northeastern India very soon, provided we keep them undisturbed and allow them to follow their own course.
