<meta content="We predict the decadal change in position of
three American Samoa mangroves from analysis of a
time series of remotely sensed imagery, a geographic
information system, tide gauge data, and projections
for change in sea-level relative to the mangrove surface.
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="We predict the decadal change in position of
three American Samoa mangroves from analysis of a
time series of remotely sensed imagery, a geographic
information system, tide gauge data, and projections
for change in sea-level relative to the mangrove surface.
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

three American Samoa mangroves from analysis of a&#13;
time series of remotely sensed imagery, a geographic&#13;
information system, tide gauge data, and projections&#13;
for change in sea-level relative to the mangrove surface.&#13;
Accurate predictions of changes to coastal ecosystem&#13;
boundaries, including in response to projected relative&#13;
sea-level rise, enable advanced planning to minimize&#13;
and offset anticipated losses and minimize social disruption&#13;
and cost of reducing threats to coastal development&#13;
and human safety. The observed mean landward&#13;
migration of three mangroves’ seaward margins&#13;
over four decades was 25, 64, and 72mma−1, 12 to&#13;
37 times the observed relative sea-level rise rate. Two&#13;
of the sites had clear trends in reductions in mangrove&#13;
area, where there was a highly significant correlation&#13;
between the change in position of the seaward mangrove&#13;
margin and change in relative sea-level. Here&#13;
it can be inferred that the force of sea-level rise relative&#13;
to the mangrove surface is causing landward migration.&#13;
Shoreline movement was variable at a third&#13;
site and not significantly correlated with changing sealevel,&#13;
where it is likely that forces other than change in&#13;
relative sea-level are predominant. Currently, 16.5%,23.4%, and 68.0% of the three mangroves’ landward&#13;
margins are obstructed by coastal development from&#13;
natural landward migration. The three mangroves could&#13;
experience as high as a 50.0% reduction in area by&#13;
the year 2100. A 12% reduction in mangrove area&#13;
by the year 2100 is possible in the Pacific islands&#13;
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&#13;
