These techniques involve creation of water areas, alteration of salinity levels, damming and diking, burning, harvest of marsh grasses, and direct planting and seeding. Marsh fires can be classified as cover, root, or peat burns. Cover burns are light and are usually carried out between 15 October and 1 March. Root burns are hotter and are designed to alter vegetative composition through control and replacement of various low-value marsh species. They must be undertaken when the marsh floor is dry to be effective, necessitating care to prevent damage to wildlife.
Peat fires burn holes in the marsh floor to provide additional water areas.
