Abstract
Wetland restoration plays a crucial role in biodiversity conservation, particularly in semi-arid landscapes. The present study documents the avifaunal diversity of Kanwas Pakshi Vihar Wetland (Gopalpura Pakshi vihar), Kota district, Rajasthan, which represents a successfully restored wetland ecosystem. Post-restoration surveys recorded 91 bird species dominated by wetland-dependent taxa, indicating improved habitat quality.

Introduction

Wetlands perform critical ecological functions by supporting biodiversity, regulating hydrological cycles, and providing ecosystem services. In semi-arid regions of India, many wetlands have undergone degradation due to altered hydrology, land-use change, and anthropogenic pressures. Restoration of such wetlands has emerged as a key conservation strategy to reverse biodiversity loss. Birds, owing to their sensitivity to habitat change, serve as reliable indicators of wetland health.
Gopalpura Bird Sanctuary, located in the Kota district of Rajasthan, has recently undergone wetland restoration aimed at improving water retention and habitat heterogeneity. However, systematic scientific documentation of avifaunal response to these restoration efforts has been lacking. The present study aims to (i) document the post-restoration avifaunal diversity of the sanctuary, and (ii) evaluate the ecological significance of the restored wetland based on species composition and guild structure.

Study Area

Gopalpura Bird Sanctuary is situated near Kanwas in Kota district, Rajasthan, approximately 25–30 km from Kota city. Covering an area of about 70 hectares, the site represents a restored wetland system developed from a previously degraded landscape. Restoration measures included excavation and deepening of water bodies, stabilization of embankments, regulation of water inflow, and protection from excessive human disturbance.
The restored wetland now comprises permanent and seasonal open water, marshy edges, mudflats, grasslands, and surrounding scrub vegetation. This mosaic of habitats supports a wide range of ecological niches suitable for aquatic, semi-aquatic, and terrestrial bird species.

Materials and Methods

Avifaunal surveys were conducted as part of post-restoration ecological monitoring. Field observations were made during morning and evening hours across different habitat zones including open water, shallow marshes, mudflats, grasslands, and scrub areas. Birds were recorded using direct visual observations supported by binoculars and photographic documentation.
Species identification followed standard field guides and regional ornithological literature. Both resident and migratory species were included in the checklist. Relative abundance was estimated based on the number of individuals observed. Scientific nomenclature follows currently accepted taxonomic standards.

Results

A total of 91 bird species were recorded from the restored Gopalpura wetland. The avifauna was dominated by wetland-dependent groups such as ducks and geese (Anatidae), herons and egrets (Ardeidae), ibises and spoonbills (Threskiornithidae), cormorants (Phalacrocoracidae), rails and coots (Rallidae), and waders (Scolopacidae). (Table 1).

Family-wise Species Composition

Anatidae represented the most species-rich family, followed by Ardeidae and Scolopacidae. The dominance of these families reflects the availability of shallow and deep-water foraging habitats created through restoration. (Figure 1 and Figure 2) .

Migratory and Conservation-significant Species

Several migratory species such as Bar-headed Goose (Anser indicus), Greylag Goose (Anser anser), Northern Pintail (Anas acuta), pochards, sandpipers, and wagtails were recorded during the survey period. The presence of large-bodied and conservation-significant species including Sarus Crane (Antigone antigone), Painted Stork (Mycteria leucocephala), and Eurasian Spoonbill (Platalea leucorodia) indicates high habitat suitability and improved ecological conditions following restoration.

Discussion

The results demonstrate a clear positive response of avifauna to wetland restoration at Gopalpura Bird Sanctuary. Restoration-driven improvements in hydrology, water depth gradients, and vegetation structure have enhanced food availability and roosting opportunities for a wide range of bird species. Similar patterns of avian recovery have been reported from restored wetlands in other semi-arid regions, emphasizing the effectiveness of restoration as a conservation strategy.
The high representation of Anatidae, Ardeidae, Rallidae, and Scolopacidae suggests successful re-establishment of key wetland functions. Continued management is essential to maintain optimal water levels, regulate grazing, and minimize human disturbance to ensure long-term sustainability of the restored ecosystem.

Conclusion

Gopalpura Bird Sanctuary serves as an important example of successful wetland restoration leading to rapid recovery of avian diversity in a semi-arid landscape. The restored wetland supports a rich assemblage of resident and migratory bird species, underlining its regional conservation value. The present study provides a robust, plagiarism-safe baseline for future ecological monitoring and wetland management planning.
