Figure 5: Vulnerability of coastal Louisiana wetlands to present-day rates of RSLR.
From: Vulnerability of Louisiana’s coastal wetlands to present-day rates of relative sea-level rise
(a) Mississippi Delta; (b) Chenier Plain. Sites that fall within the accretion surplus field have VA rates that exceed the rate of RSLR. Sites within the grey buffer zone have an accretion deficit that is <2 mm per year and are assumed herein not to be vulnerable (although this is uncertain). Sites that fall below this buffer zone have an accretion deficit >2 mm per year and are considered vulnerable given current rates of RSLR. Outliers in the Mississippi Delta (n=5, with 4 experiencing an accretion surplus) are not shown for ease of comparison between the two regions.
