Background information and definitions
Littoral marshes and swamps (i.e. on sea or lake shores) are vulnerable to erosion and physical damage from boat and jet ski wakes – especially when this activity is regular, concentrated and close to the shore (Bilkovic et al. 2017). Barriers between focal marshes or swamps and the main water body may help to diffuse energy. Barriers might be dykes, walls, breakwaters, reefs, or even created marshes or swamps!
Related actions: Use artificial barriers to block pollution; Build barriers to protect littoral habitats from rising water levels and severe weather (freshwater marshes – brackish/salt marshes – freshwater swamps – brackish/saline swamps); Use fences or barriers to protect planted areas (freshwater non-woody – brackish/saline non-woody – freshwater trees/shrubs – brackish/saline trees/shrubs).
