Background information and definitions
Areas could be left undeveloped as spaces for migration of marshes and swamps as climate changes and sea levels rise. This philosophy should be integrated into urban planning, especially along coastlines (Green et al. 2009). For example, in Yankeetown on the coast of Florida, USA, development is prohibited within 50 feet of a wetland to allow space for migration with sea level rise (Anon 2016). Areas for migration should be of reasonable size and ideally connected to existing marshes or swamps. Barriers to habitat migration, such as roads and embankments, may need to be actively removed. Long-term land ownership issues should be considered; it may be necessary to purchase areas designated for habitat migration (DELWP 2016).
We realize that providing evidence for the effects of this intervention will be difficult, but include the action for completeness: it is something that could be done to conserve marsh or swamp vegetation.
