Texte intégral

Unknown effectiveness (limited evidence)

Maintain/restore water flow across service corridors

1Characteristic plants: One before-and-after study in a fen in the USA found that after restoring water inflow across a road, along with general rewetting, cover of wet peatland sedges increased whilst cover of grasses preferring drier conditions decreased.

2Assessment: unknown effectiveness – limited evidence (effectiveness 60 %; certainty 20 %; harms 1 %). Based on evidence from: fens (one study).


No evidence found (no assessment)

4We have captured no evidence for the following interventions:

  • Backfill trenches dug for pipelines
  • Retain/create habitat corridors across service corridors.
