Forest loss is the area within 100 m of tidal marsh that</div><div>experienced loss between 2000-2018 (as a proportion of the patch), from Hansen et al. (2018).</div><div>Area of marsh (ha) that is behind a tidal restriction is from University of Massachusetts</div><div>Landscape Ecology Lab’s Designing Sustainable Landscapes:</div><div>https://jamba.provost.ads.umass.edu/web/lcc/dsl/metrics/DSL_documentation_tidal_restrictio</div><div>ns.pdf. Sea-level rise rate (mm/year) is from the NOAA tide gauge that is closest to the marsh</div><div>patch. </div></div>
