<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Virginia Institute of Marine Science published the first Tidal marsh Inventories using data collected in the early 1970's. </SPAN><SPAN>Using high resolution color infra-red imagery from 2009, 2011 and 2013 new Tidal Marsh Inventories have been developed beginning in 2010. Marsh boundaries were generated using heads-up digitizing techniques at a scale of 1:1,000. From 2010 through 2014 marsh polygons were classified by morphologic type: fringe, extensive, embayed, or marsh island. Beginning in 2015, morphologic classification was discontinued. Marshes were ground-truthed in the field where a community type index was assigned to each marsh based on plant community make-up.</SPAN></P><P><SPAN /></P><P><SPAN /></P></DIV></DIV></DIV> |
