Action: Retain/create habitat corridors across service corridors
Key messagesRead our guidance on Key messages before continuing
- We found no studies that evaluated the effects on peatland vegetation, in habitat patches or within corridors, of retaining/creating habitat corridors across service corridors.
‘We found no studies’ means that we have not yet found any studies that have directly evaluated this action during our systematic journal and report searches. Therefore we have been unable to assess whether or not the action is effective or has any harmful impacts. Please get in touch if you know of such a study for this action.
Habitat corridors are strips that link two larger habitat patches – in this case preventing peatland patches being separated by transportation or service corridors. By connecting the habitat patches, habitat corridors could improve survival prospects of peatland plant populations. Seeds, pollen or vegetation fragments can more easily move between the habitat patches (perhaps carried by animals), maintaining populations and diversity in each (Damschen et al. 2006).
Caution: Habitat corridors can have negative effects. For example, corridors can allow diseases and non-native species to spread between patches (Resasco et al. 2014).
Key peatland types where this action may be appropriate: bogs, fens/fen meadows, tropical peat swamps.
Related actions: maintaining/creating habitat corridors in areas of energy production or mining; general habitat creation and restoration.
