Accurate predictions of changes to coastal ecosystem boundaries, including in response to projected relative sea-level rise, enable advanced planning to minimize and offset anticipated losses and minimize social disruption and cost of reducing threats to coastal development and human safety. The observed mean landward migration of three mangroves’ seaward margins over four decades was 25, 64, and 72mma−1, 12 to 37 times the observed relative sea-level rise rate. Two of the sites had clear trends in reductions in mangrove area, where there was a highly significant correlation between the change in position of the seaward mangrove margin and change in relative sea-level. Here it can be inferred that the force of sea-level rise relative to the mangrove surface is causing landward migration. Shoreline movement was variable at a third site and not significantly correlated with changing sealevel, where it is likely that forces other than change in relative sea-level are predominant. Currently, 16.5%,23.4%, and 68.0% of the three mangroves’ landward margins are obstructed by coastal development from natural landward migration. The three mangroves could experience as high as a 50.0% reduction in area by the year 2100. A 12% reduction in mangrove area by the year 2100 is possible in the Pacific islands region." name="eprints.abstract" /> <meta content="2007-01" name="eprints.date" /> <meta content="published" name="eprints.date_type" /> <meta content="Environmental Monitoring Assessment" name="eprints.publication" /> <meta content="124" name="eprints.volume" /> <meta content="1- 3" name="eprints.number" /> <meta content="105-130" name="eprints.pagerange" /> <meta content="10.1007/s10661-006-9212-y" name="eprints.id_number" /> <meta content="TRUE" name="eprints.refereed" /> <meta content="0167-6369" name="eprints.issn" /> <meta content="http://dx.doi.org/10.1007/s10661-006-9212-y" name="eprints.official_url" /> <meta content="Allen, J.A.

Accurate predictions of changes to coastal ecosystem boundaries, including in response to projected relative sea-level rise, enable advanced planning to minimize and offset anticipated losses and minimize social disruption and cost of reducing threats to coastal development and human safety. The observed mean landward migration of three mangroves’ seaward margins over four decades was 25, 64, and 72mma−1, 12 to 37 times the observed relative sea-level rise rate. Two of the sites had clear trends in reductions in mangrove area, where there was a highly significant correlation between the change in position of the seaward mangrove margin and change in relative sea-level. Here it can be inferred that the force of sea-level rise relative to the mangrove surface is causing landward migration. Shoreline movement was variable at a third site and not significantly correlated with changing sealevel, where it is likely that forces other than change in relative sea-level are predominant. Currently, 16.5%,23.4%, and 68.0% of the three mangroves’ landward margins are obstructed by coastal development from natural landward migration. The three mangroves could experience as high as a 50.0% reduction in area by the year 2100. A 12% reduction in mangrove area by the year 2100 is possible in the Pacific islands region.</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Additional Information:</th><td valign="top" class="ep_row">The original publication is available at www.springerlink.com </td></tr><tr><th valign="top" class="ep_row">Keywords:</th><td valign="top" class="ep_row">American Samoa .
