Texte intégral

Unknown effectiveness (limited evidence)

Physically exclude vehicles from peatlands

1Vegetation structure: One replicated, paired, controlled, site comparison study in a floating fen in the USA reported that fencing off airboat trails allowed total and non-woody vegetation biomass to increase, up to levels recorded in undisturbed fen. Woody plant biomass did not recover.

2Overall plant richness/diversity: The same study reported that fencing off airboat trails allowed overall plant diversity to increase, recovering to levels recorded in undisturbed fen.

3Assessment: unknown effectiveness – limited evidence (effectiveness 70 %; certainty 35 %; harms 0 %). Based on evidence from: fens (one study).​actions/​1750

No evidence found (no assessment)

4We have captured no evidence for the following interventions:

  • Restrict vehicle use on peatlands
  • Restrict pedestrian access to peatlands
  • Physically exclude pedestrians from peatlands
  • Install boardwalks/paths to prevent trampling
  • Wear snowshoes to prevent trampling
  • Adopt ecotourism principles/create an ecotourism site.
