Introduce plants to marshes or swamps to control pollution
Overall effectiveness category No evidence found (no assessment)
Number of studies: 0
Background information and definitions
This action involves introducing vegetation into polluted marshes or swamps, with the intention that the introduced plants help to control pollution (Bert et al. 2009). Plants can help to clean up existing pollutants, or manage chronic inputs of pollutants. Plants may directly absorb or break down pollutants, or facilitate break down by microbes through providing oxygen and a large surface area (Brix 2003). To be summarized as evidence for this action, studies must report effects on desirable marsh or swamp vegetation other than that planted to control pollution.
