The northward expansion of Spartina alterniflora (S. alterniflora) poses a profound ecological threat to coastal ecosystems and biodiversity along China’s coastline. This invasive species exhibits strong adaptability colder climates, facilitating its potential spread into northern regions underscoring the urgent need for nuanced understanding spatial distribution invasion risks inform evidence-based ecosystem management strategies. study employed multi-temporal Sentinel-1/2 imagery (2016–2022) map predict S. in Bohai Bay. An object-based random forest classification achieved an overall accuracy above 92% (κ = 0.978). Over six-year period, decreased from 46.60 km2 2016 12.56 2022, reflecting annual reduction approximately 5.67 km2. decline primarily resulted targeted eradication efforts, including physical removal, chemical treatments, biological competition Despite this local reduction, MaxEnt modeling suggests that climate trends habitat suitability continue support expansion, particularly high-risk areas such as Binhai New District, Shandong Yellow River Delta, Laizhou Bay tributary estuary. Key environmental drivers include maximum temperature warmest month, mean wettest quarter, isothermality, sea surface temperature, soil type. High-risk zones, covering about 95.65 These findings illuminate dynamics offer scientific guidance restoration strategies, ensuring protection fostering sustainable development.
