Background information and definitions
Removing other plants before or after planting desirable marsh or swamp plants could reduce competition for space, light and nutrients. Survival and growth of planted vegetation may be improved. Note that abundant competitors, and/or the absence of the vegetation to be introduced, could be symptoms of inappropriate physical conditions that may also need to be managed. Also note that existing vegetation may help to protect planted vegetation from extreme temperatures and sunlight, and protect the wetland surface from erosion.
To be clear, this action includes various specific actions that remove undesirable plants (e.g. physical removal, mowing, herbicide application) or kill undesirable seeds (e.g. burning, covering the soil with black plastic) in areas planted with desirable marsh or swamp plants. Management might be one-off or continuous. Evidence summarized for this action focuses on responses of the planted vegetation; studies that report responses of other vegetation are included in separate interventions elsewhere on this site.
Related actions: Introduce nurse plants before/after planting target marsh or swamp vegetation.
