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 &gt;0.4m, elevation low &lt;= 0.4m, UVVR low &lt;= 0.15, UVVR High &gt; 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>",
