In total, 61 odonates, 51 buterfies, 17 species of amphibians and reptles, 90 birds, and four mammals are documented. Our observatons taken over a brief tme refect the importance of citzen science in documentng local biodiversity. We report involvement of citzen scientsts in recovering signifcant odonate records for the state. Keywords: Biodiversity, conservaton, freshwater ecosystem, northern Western Ghats, Odonata, wetland.

INTRODUCTION of the state and includes parts of northern Western Ghats, locally known as Sahyadri Hill ranges. Dhamapur The indeterminate exploitaton of the natural Lake (16.033°N & 73.593°E; 22m) is located in the resources by humans has caused considerable Malvan Tehsil of Sindhudurg District (Figure 1, Image alteratons in the ecosystem functoning and biodiversity 1). The climate of Malvan Tehsil remains hot and loss through urbanizaton, habitat destructon, habitat humid throughout the year having an annual average modifcaton, and degradaton of vital freshwater temperature 27.1°C and average annual precipitaton of resources (Gleick et al. 2001; McKinney 2002; Diaz et 2,865mm (Malvan summary 2020). al. 2006; Dudgeon et al. 2006). Despite the current The lake is a 400 years old human-made lake with body of knowledge of environmental degradaton, an area of 22 hectares. It provides water to Malvan several regions remain less explored in terms of data City (TERI 2013). The surrounding villages Dhamapur on biodiversity. The lack of knowledge on biodiversity and Walvali depend on its water for domestc use and hampers the decision making at policy level and hence irrigaton purposes. The forest around the lake is moist considered as one of the global priorites when forming deciduous and categorised as reserve forest. Streams conservaton frameworks (Meyer et al. 2015; Sorte & having varying canopy cover, fow along one side of the Somveille 2020). In recent years, citzen science has lake (Image 3), while the other side is surrounded by proved to be a benefcial tool in collectng biodiversity marshes and paddy felds (Image 2). data through people’s partcipaton (Theobald et al. 2015; Chandler et al. 2017; Mckinley et al. 2017). It Survey sites is used for research, to understand distributon and We surveyed various freshwater habitats like lakes, possible threats to multple taxa like insects, amphibians, ponds, wells, and streams around Dhamapur Village birds, and mammals (Kolby 2015; Forrester et al. 2017; as our focal taxon was odonates. We also surveyed Zapponi et al. 2017; Sorte & Somveille 2020). In India, the natural vegetaton, paddy-felds and forest patches the practce of citzen science has proved as a useful around these habitats. Details of the study sites are tool for biodiversity documentaton at fner spatal scale given in Table 1 (Images 2–6). (Badrinath 2015; Seshadri & Gururaja 2015; SoIB 2020). DragonfySouthAsia (DSA), a part of DiversityIndia Data collecton (htp://diversityindia.org/), is a citzen science network The 6th DragonfySouthAsia meet was conducted of Odonata (dragonfies and damselfies) watchers and during 10–13 October 2019 wherein a total of 25 people researchers from the Indian subcontnent (htps:// partcipated from India and Sri Lanka.

DSA has been of Syamantak, a local community working towards actvely involved in conservaton outreach and research, conservaton of wetlands in the Sindhudurg area (htp:// popularizing odonatology and freshwater conservaton syamantak.cfsites.org/), also took part. through meets and workshops every year since 2014 On all the four days, we opportunistcally surveyed (Andrew et al. 2015; Dawn & Roy 2017; Koparde et the sites for rapid assessment of selectve invertebrates al. 2018, 2020), and facilitatng collaboratve research and vertebrates. Rapid mult-taxa assessments are (Mujumdar et al. 2018). In the current survey, we used a used to yield quick yet reliable results. These are combinaton of rapid mult-taxa assessment and citzen cost-efectve, useful to make inventories of the local science to document biodiversity in Dhamapur Lake area biodiversity, and the informaton obtained in terms of taking odonates as target taxa. Here, we demonstrate species richness can be used potentally to represent that peoples’
