Abstract

Temporary wetlands (TW) are distinguished by a distinct collection of uncommon and specialised ora
and fauna species, modest size, periodical drying, and plentiful water during the ood 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 signi cant 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-ve 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 modi cation, 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 t other sections of TW and detect ecological status and human
effect on wetlands, which will improve TW conservation and management decisions.
