Background information and definitions
In degraded marshes or swamps, the surface soil/sediment – and any vegetation on it – could be buried under deeper layers, for instance by deep ploughing. Burial can create bare soil/sediment with spaces for vegetation to grow, prevent undesirable plants from growing from seeds already in the soil, remove excess nutrients that favour growth of undesirable weedy plants, and remove any contaminants or pollutants (Glen et al. 2017). Inverting, rather than removing, the upper soil layer maintains the ground level.
Caution: Heavy machinery is usually needed for this action. Heavy vehicles can churn and compress wetland soils (Campbell et al. 2002).
Related actions: Remove surface soil/sediment without replacement (freshwater marshes – brackish/salt marshes – freshwater swamps – brackish/saline swamps); Disturb soil/sediment surface (freshwater marshes – brackish/salt marshes – freshwater swamps – brackish/saline swamps); Bury surface soil/sediment before planting.
