Background information and definitions
Habitat corridors are strips that link two larger habitat patches – in this case preventing peatland patches being separated by development. By connecting the habitat patches, 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 also have negative effects, like allowing diseases, non-native species and fire 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: rewetting, because peatlands may be drained to allow development or are dried out by drainage of sites nearby; habitat creation and restoration interventions.
