Background information and definitions
The impact of hunting/collecting animals from marshes or swamps could be reduced by switching to lower-impact methods or equipment. Accessing marshes or swamps by foot may cause less damage to vegetation than using vehicles. Canoes or hovercraft may cause less damage to vegetation than motorboats. In Brazilian mangroves, reverting to the traditional, manual braceamento technique to collect crabs may be less damaging than the fashionable, more profitable redinha technique – which involves cutting mangrove trees in order to set crab traps (do Nascimento et al. 2011; Walsh 2017).
To be included as evidence for this action, studies must have compared low- and high-impact hunting methods, not just reported the effects of methods claimed to be low-impact.
