Study of the Avian Diversity in Jasder Dham, Barmer, Rajasthan
Abstract
Jasder Dham is a unique site in Barmer, Rajasthan. Despite being located in an arid region, the presence of a pond supports a significant diversity of aquatic birds. This research study aims to investigate the avian diversity within Jasder Dham, driven by the need to understand the ecological significance of this unique habitat and its role in supporting avian populations.
Avian diversity studies in the arid zones of Rajasthan have been relatively limited. This research seeks to fill this gap by providing valuable insights into the bird species of various families inhabiting Jasder Dham.
The findings of this study will contribute to our understanding of the avian community structure in arid ecosystems, particularly in the context of Barmer, Rajasthan. Furthermore, the results may have implications for conservation efforts, as the identification of key bird species and their ecological requirements can guide conservation strategies aimed at preserving biodiversity in this unique habitat. Overall, this research serves as a valuable addition to the knowledge base on avian diversity in arid regions, emphasizing the importance of holistic conservation approaches for sustaining ecological balance.

Introduction
Rajasthan, situated in northwestern India, is a state renowned for its rich birdlife despite facing water scarcity. Remarkably, this state, comprising only 10% of India'sgeographical area, is home to approximately 40% of the country'savifauna (1224 species). This high avian diversity can be attributed to the region'sdiverse habitats and its location within a major migratory bird flyway.
An estimated 510 bird species are believed to occur in Rajasthan (Grimmett and Inskipp 2003), with 496 species recorded to date (Devarshi, D. 2004), representing around 40% of the Indian avifauna.
Our understanding of Barmer'savian fauna has been enriched by several studies. Rahmani (1997) conducted a comprehensive survey, documenting 213 species, including 35 in Barmer, highlighting the presence of diverse avian populations, even in this arid region. Subsequent studies, such as those by Sivaperuman et al. (2005) and Kumar et al. (2006), further expanded our knowledge. Kumar et al. (2006), focusing on wetland birds, listed 53 species from Barmer in their 'Geo-spatial Atlas for the wetland birds of GITD.' More recently, as part of the Zoological Survey of India'sassessment of the impact of proposed lignite mining in the Kapurdi and Jalipa Blocks and the surrounding 10-kilometer radius of Barmer district, "General Faunistic Surveys" were conducted. These surveys, covering approximately 850 square kilometers, meticulously recorded avian species, resulting in a comprehensive bird checklist for the Barmer district. This checklist encompasses a total of 153 species, representing 103 genera and 46 families (Tak et al., 2009).
Conclusion
This study provides valuable insights into the avian community composition, ecological interactions, and conservation needs within the Jasder Dham region. Conservation strategies should prioritize the protection of critical habitats, maintaining ecological connectivity, and mitigating threats such as habitat loss, pollution, and climate change.
