Checklist of the lake aquatic macrophytes in Dhamdha block, Durg district, Chhattisgarh state of India

Abstract

During this study 26 lakes are investigate for aquatic macrophyte diversity and to understand the lake ecosystem dynamics and aquatic macrophytes species composition of Dhamdha in 2021-22. It is widely known that Chhattisgarh has abundant freshwater resources. There are 1.64 lakh hectares of water accessible for fish cultivation in Chhattisgarh. In Chhattisgarh, Dhamdha is renowned for its abundant natural water resources. However, the natural resources were disappearing daily. Twenty-five different species of aquatic macrophytes were found in the lake that was the subject of the investigation. These species were distributed throughout 38 genera, encompassing the taxonomic categories angiosperms, bryophyta, and charophyta. Among the year-round species are Eichornia crassipes, Vallisneria spiralis, Hydrilla verticillata, Ipomoea aquatic and Ipomaea carnea. During the monsoon, several species of floating aquatic macrophytes were found, including Ipomoea aquatic, Vallisneria spiralis, Hydrilla verticillata, and Eichornia crassipes. As the depth of the water increased, these species florished and took over the auqa-regime. Prominent phytosocial connections have been seen between a number of aquatic macrophytes, including Hydrilla verticillata, Vallisneria spiralis, and Chara sp. Vallisneria spiralis, Najas minor, Potamogeton pectinatus and Valisneria were shown to have similar associations.
