Background information and definitions
The impact of biological resource harvests could be reduced by better planning and/or using alternative techniques. For example, vehicles used for harvesting can compress, sink into and create ruts in wet peat soils. These impacts can be reduced by planning routes so the same ground is not repeatedly crossed, whilst ensuring vehicles are not overloaded and heavy (Schröder et al. 2015). Bails of vegetation could be rolled behind vehicles rather than carried on vehicles, spreading their weight over a larger area (Dubowski et al. 2013). In tropical forests, techniques to reduce logging impacts include directing the fall of felled trees, cutting lianas before felling (so they don’t drag down other trees linked to the felled tree) and planning to keep disturbance from roads as small as possible (FAO 2004).
To be included as evidence, studies must have compared low impact harvesting techniques with alternative, traditional techniques.
Key peatland types where this action may be appropriate: bogs, fens/fen meadows, tropical peat swamps.
