Physically remove problematic plants: freshwater swamps

Background information and definitions
This action considers complete physical removal of problematic plants, i.e. pulling up or digging up entire plants, or scraping living vegetation from the swamp surface. Removal may be targeted to individual organisms, or applied to the whole plant community. The most appropriate removal method will depend on the species to be removed, and the site conditions (e.g. Tobias et al. 2016).
If plants are completely removed, including roots where applicable, immediate regrowth will be prevented (although long-term recolonization from the seed bank or from neighbouring sites is possible). For some species, disposing of the problem plants off-site may help to prevent regrowth, but disposal should be done carefully to avoid causing an invasion elsewhere (Stevens et al. 1997).
For this action, “vegetation” refers to overall or non-target vegetation. Studies that only report responses of target problematic plants have not been summarized.
