Use low-impact methods to harvest vegetation: freshwater marshes
Overall effectiveness category No evidence found (no assessment)
Number of studies: 0
Background information and definitions
The impact of harvesting vegetation could be reduced by switching to supposedly lower-impact methods or equipment. For example, vehicles used for harvesting can compress, sink into and create ruts in wet soils. Lower-impact alternatives include: using specialised tracked vehicles or hovercraft which exert less pressure on the ground (Dubowski et al. 2013); ensuring vehicles are not overloaded and heavy (Schröder et al. 2015); and extracting harvested vegetation by hand or helicopter. When logging in swamps, directional felling may reduce the amount of collateral damage when trees fall.
To be included as evidence for this action, studies must have compared low- and high-impact harvesting methods, not just reported the effects of methods claimed to be low-impact.
