Unknown effectiveness (limited evidence)

● Re-route paths to reduce habitat disturbance

1One before-and-after trial in Australia found that closing paths did not alter shrub cover, but did increase the number of plant species in an alpine shrubland. Assessment: unknown effectiveness (effectiveness 30%; certainty 10%; harms 0%).


No evidence found (no assessment)

3We have captured no evidence for the following interventions:

  • Use signs and access restrictions to reduce disturbance
  • Plant spiny shrubs to act as barriers to people.
