The study area encompasses a total land area of 480 acres(including a 104 acres waterbody with an island in the middle), comprising a varied array of microhabitats consist of grassland, a mixed forest. Located on a periphery of the park, there exists a diminutive expanse of wetland referred to as Pakhibitan, characterized by the presence of cattails, colloquially known as 'hogla' among the indigenous populace. Located opposite the park lies a substantial body of freshwater, encompassing an approximate surface area of 104 acres. Vegetation associated with the beetle species are in the study area Nymphoides indica, Typha elephantina, Ludwigia adscendens, Eichornia crassipes, Cynodon dactylon. The annual temperature exhibits a range of 43°C to 9°C. The annual average precipitation is 1400mm. The soil type in this area is classified as alluvial due to its geographical location within the Indo-Gangetic plain. Various parameters were recorded during the survey, these are pH, TDS, EC, salinity and DO. pH recorded was from 7 to 11. TDS was 283± 10 ppm. With EC 566± 20 μs/cm, DO was 6.12± 1.28 mg/l. Salinity was 0% and remained same throughout the study period The dataset presented here comprises a record of aquatic beetles documented during a biodiversity survey conducted over the period spanning from april 2023 to march2024. All species have been identified at either the species or genus level. A comprehensive tally of 13 species was documented belonging to 3 separate families under order coleoptera. We are grateful to West Bengal Housing Infrastructure Development Corporation (WBHIDCO) for allowing us to use Ecopark as a study area.
