The conservation and management of temperate marshes, bogs and other wetlands. The principal wetland management techniques are classified as mechanical, chemical, biological, and cultural. Controlled burning is considered a cultural technique of proven value. Superficial burns over saturated soils remove current growth and accumulated litter. Total elimination of perennial vegetation is possible during deep burns when the marsh is dry.
Deep burns increase the depth of the marsh, setting back succession to submergent stages.
Cultivation is sometimes necessary if ash deposits are deep.
