Parent Layer: Marsh Conservation and Management - 1 meter of SLR by 2100 Scenario

Name: Marsh Viability by Census Block Group in 2100

Display Field: stfid

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This dataset shows the most and least viable salt marshes (irregularly flooded and regularly flooded) by census block group in 2100 under a 1 meter SLR scenario. Marsh viability was calculated by comparing the initial marsh footprint within each census block to that which is predicted to remain by 2100. This was accomplished by summing marsh losses, gains and persistence and dividing that by the initial marsh area within the census block group. The 5 classes shown (1= high viability and 5=Low viability) were classified based on a Natural Breaks classification which helps to show maximum differences in marsh viability per census block group. Census blocks which did not intitally contain salt marsh but gained marsh by 2100 were given a rank of 6 and those without marsh were given a rank of 0. This dataset is based on results from the application of SLAMM. <a href='xml/gulfmex_TX_CC_MarshViability_2100_1m_SLR.xml' target='_blank'><b>Metadata</b><a></br>
