Climate change and loss of saltmarshes: consequences for birds

摘要: Saltmarshes are areas of vegetation subject to tidal inundation and important birds for several reasons. high primary productivity their greatest significance coastal is probably as the base estuarine food webs, because saltmarshes export considerable amounts organic carbon adjacent habitats, particularly invertebrates mudflats. In addition, direct importance by providing sites feeding, nesting roosting. Climate change can affect in a number ways, including through sea-level rise. When rises marsh moves upward inland but sea walls that prevent this said lead squeeze loss area. However, evidence from southeast England, elsewhere, indicates rise does not necessarily area marshes accrete vertically maintain elevation with respect where supply sediment sufficient. Organogenic those may be more limiting (e.g. some west coast areas) susceptible squeeze, other marshes, if extreme predictions accelerated rates realized.
