Background information and definitions
Isolated habitat patches can be linked with continuous habitat corridors, or with discrete habitat patches as stepping stones (Bennett 2003). Linkages could improve survival prospects and diversity of plant populations in habitat patches (Damschen et al. 2006), because seeds, pollen or vegetation fragments can be moved along them (e.g. by animals). Caution: Habitat linkages can also allow diseases, non-native species and fire to spread between patches (Resasco et al. 2014).
Studies of this action could involve linkages of any habitat type, as long as effects on marsh or swamp vegetation are evaluated.
