Ecological Status of Temporary Wetlands in Central Tamilnadu District, India.

Abstract Temporary wetlands (TW) are distinguished by a distinct collection of uncommon and specialised flora and fauna species, modest size, periodical drying, and plentiful water during the flood season. The Indian subcontinent is home to a diverse range of freshwater, saline, and marine wetlands. The bulk of the inward wetlands are manmade or transitory, and they have traditionally been used by regional human groups. Most limnological research in India have focused on large, permanent bodies of water, pond ecosystems, and associated temporary wetlands.Furthermore, numerous Temporary Wetlands (TW) in Tamil Nadu State (TNS) offer significant potential for ecosystem service applications but are not yet well documented. Due to a lack of study, the existing survey explores the Ecological status (ES), distribution of Temporary Wetlands (TW), and individual wetland human disturbance score (HDS) in the Central Tamil Nadu district (CTND) in India. Seventy-five selected wetlands were surveyed using a variety of approaches in three districts: Karur, Namakkal, and Trichy. During the summer, all wetlands were hydrologically separated and parched.The TW size ranged from 1 to 10 acres, with 80 percent located in rural regions, 12 percent in semi-urban areas, and 8 percent in metropolitan areas. Wetland degradation was highest in Trichy district wetlands (TDW) at 76 percent Mid Impact (MI), followed by Namakkal district wetlands (NDW) at 36 percent MI, and Karur district wetlands (KDW) at 20 percent MI. Wetland degradation is often caused by landscape disturbance, buffer zone modification, hydrological alteration, pollution, and ecosystem alteration. The current study provides baseline facts on the biological state and distribution of Temporary Wetlands in CTND, which could help in the creation of provincial wetland management strategy. This method will fit other sections of TW and detect ecological status and human effect on wetlands, which will improve TW conservation and management decisions.
