  • The Indian River Lagoon, including Mosquito Lagoon, experienced a significant decline in seagrass, a foundational ecosystem component, primarily due to harmful algal blooms since 2011.
  • The loss of seagrass resulted in economic and ecological impacts, such as undermining fisheries and tourism, and causing the starvation of over 1,200 manatees between 2020-2025.
  • Hurricane Ian and Hurricane Nicole in fall 2022 exacerbated the decline, pushing seagrass cover to near zero in Mosquito Lagoon.
  • Using satellite imagery and machine learning, researchers documented a remarkable seagrass recovery beginning in March 2023, reaching over 20% coverage by July 2023.
  • The return of seagrass demonstrated an unexpected resilience of the system, though the complete recovery remains at a cautious level considering seasonal fluctuations and algal blooms.
  • This recovery suggests that hurricanes may have altered conditions beneficial for seagrass, but further research is required to confirm this mechanism.
  • The study highlights the value of satellite remote sensing and machine learning in monitoring ecosystem changes and responding to marine ecological issues.
