Stocking et al. 2025 looked at how mud and sand are building up or washing away in parts of Eeyou Istchee (northeastern James Bay), where eelgrass is trying to grow back after a big decline in the 1990s. Nearby rivers, especially La Grande River, bring in a lot of these sediments. Since eelgrass helps keep the water clear, its loss likely caused more sediment to move around, making the water cloudier and harder for eelgrass to return. The study shows it’s important to keep a close eye on how sediment changes in these areas.
