Interactions: Turbidity and submerged aquatic vegetation density

Graph showing relationship between turbidity and subaquatic vegetation densityThis relationship shows that as turbidity increases at sites, the density of eelgrass goes down. Secchi depth measures the water clarity. Higher values indicate clearer water. These data are from Willapa Bay and Coos Bay estuaries.
