摘要：China has a US$325 million program to eradicate invasive saltmarsh cord grass, Spartina alterniflora, which threatens coastal biodiversity. This article explores the post-eradication approaches to controlling re-invasion and their compatibility with an ethos of Nature based Solutions (NbS). Tracking marsh recovery at the Dongtan Nature Reserve (DNR) with remote sensing we ask: do two employed approaches - water level regulation (WLR) and vegetation management (VM) - operate synergistically or in trade-off to improve bird habitat and restore native species? Recovery was monitored using 225 Sentinel-1A SAR images (2018–2023) and 92 Sentinel-2A datasets (2017–2023). Water distribution stabilized in WLR areas since 2020 and kNDVI observations showed VM sections had a 20% faster vegetation growth rate than uncut zones. WLR and VM effectively boosted native vegetation restoration and bird habitat enhancement. Spatial correlation analyses revealed synergistic interactions between WLR and VM in 90% of the reserve, with only a minor area exhibiting trade-offs. Even in intermittently inundated zones, covering 49.1% of the reserve, where seasonal hydrological variability poses challenges for vegetation growth, the overlapping WLR and VM still jointly achieved the desired outcomes for vegetation recovery and bird habitat creation, without trade-offs. The study shows WLR and VM can be synergistically used to regenerate native vegetation and bird habitat, in alignment with the principles of Adaptive Management under NbS. Adaptive management yields multiple benefits and the DNR case is a positive model for the restoration of S. alterniflora clearance projects elsewhere. ? 2025, The Authors. All rights reserved.
