<DIV STYLE="text-align:Left;"><P><SPAN>Marsh health sub-layer within the Marsh Resilience Portfolio, maximum 15 points. </SPAN><A href="https://geonarrative.usgs.gov/ccl/fabric/" target="_blank" STYLE="text-decoration:underline;"><SPAN>USGS’ Marsh Lifespan Dataset</SPAN></A><SPAN> was first used to determine a ‘marsh management suggestion’ for a marsh unit. This dataset combines vegetated elevation with the Unvegetated to Vegetated Ratio (UVVR) to classify marshes as restore, protect, monitor and evaluate. For each CMU, an ELEVATION_UVVR field was calculated according to the thresholds on the chart below (elevation high >0.4m, elevation low <= 0.4m, UVVR low <= 0.15, UVVR High > 0.15). Each CMU was then scored according to its management suggestion as follows: Protect (high_low) = 15 points, monitor (low_high) = 10 points, restore (high_high) = 5 points, evaluate (low_high) = 0 points. This scoring field is labeled health_score in the MPI attribute table. You can also view the restoration suggestion of each CMU by viewing the management_strategy field within the MPI attribute table.</SPAN></P><P><SPAN>Last updated: 03/30/2026</SPAN></P></DIV> |
