Coastal wetlands provide critical ecological services but are threatened by the human, climatic, and hydrological changes impacting these ecosystems. Several key ecosystem functions rely on aquatic macrophyte plant species. We integrate 10 years of seasonal monitoring data (2014-2024) climatic datasets to assess how environmental variability influences two dominant macrophytes-the invasive non-indigenous Elodea densa Planch. Casp. (Hydrocharitaceae) native Schoenoplectus californicus (C.A.Mey.) Soják-in Chile's first Ramsar site, Carlos Anwandter, a Nature Sanctuary. modeled suitable habitat areas using MaxEnt software with Landsat 8 spectral bands indices as predictive layers. found significant recent decreases in temperature, river flow, water level, nonsignificant shift precipitation. also observed marked spatial temporal fluctuations for both macrophytes. Stepwise regression analyses indicated that expanded increasing temperature over time declined level variability. showed contrasting effects, declining rising levels expanding higher These findings emphasize complexity coastal wetland ecosystems under stress climate change need further research conservation management along migratory flyways such Southeastern Pacific Flyway.
