Background information and definitions
This action involves cutting off above-ground parts of mature shrubs and trees: plants that are too large to mow. Note that vegetation may resprout from roots or stumps that are left in place. Cutting may be done manually or with machinery, depending on the species to be cut and the site conditions. Cuttings may be removed from the site, or left in place to rot down.
Locally, it may be desirable to remove all trees/shrubs from open marshes to prevent them from developing into swamps. However, note that encroachment of woody vegetation into marshes may be necessary for habitat migration and conservation of swamps at a regional or global scale (Saintilan et al. 2014). Within swamps, it may be desirable to remove individual trees/shrubs to maintain the vegetation structure or composition.
For this action, “vegetation” refers to overall or non-target vegetation. Studies that only report responses of target problematic plants have not been summarized.
