| Abstract | Macrophytes in wetlands provide various ecosystem services and play an important role in functioning of the ecosystem. However, limited information is available for plant-specific ecosystem services within these wetlands. Within this framework, this study aimed at assessing the regulating ecosystem services (i.e., trace metal bioindicator potential, nutrient retention, carbon and nitrogen stocks) and population demography of Phragmites karka for the first time from Asia⿿s largest lagoon ecosystem. Significant differences were observed in surface water abiotic parameters and nutrients (except nitrate) and sediment variables across P. karka habitats. The concentration of Sr and Zn were higher in the sediment of P. karka habitats than plant tissues. The Enrichment Factor (EF) indicated, EF>1.5 only for Co, Mn and Zn in sediment indicating moderate anthropogenic enrichment. P. karka floating roots and roots are efficient bioindicators of Mn and Ni and Co and Na respectively. The Bio-sediment accumulation factor (BSAF) highlighted the increased accumulation (BSAF>1) of Co, Mn, Na and Ni by P. karka roots from sediment. Sediment C stocks across the 10510 ha of P. karka was 526462.22 ± 190434 Mg C with CO2 mitigation potential 1932116.36-ton CO2 and economic value of US$ 1.93 million. The sediment N stocks across 10510 ha of P. karka was 50583.60 ±16858 Mg N. Population demography showcased, the present recruitment (R0: 0.56 yr-1) of P. karka population being higher than long-term average recruitment (R: 0.50 ± 0.17 yr-1) indicating positive population growth. This growth resulted in the presence of a higher younger population (42%) compared to the older population (6%:> 4 years old) in the current sampling period. P. karka habitats of the Chilika lagoon contribute towards five sustainable development goals (SDGs) such as SDG 1,2,6, 13 and 14 highlighting the importance of P. karka regulating ecosystem services compared with similar ecosystems (e.g., seagrass) of the lagoon. |
