  <dc:description>&lt;p&gt;Multiyear remote sensing mapping of the normalized difference vegetation index (NDVI) was carried out as an indicator of live biomass composition of the &lt;i&gt;Phragmites australis&lt;/i&gt; (hereafter &lt;i&gt;Phragmites&lt;/i&gt;) marsh in the lower Mississippi River Delta (hereafter delta) from 2014 to 2017. Maps of NDVI change showed that the &lt;i&gt;Phragmites&lt;/i&gt; condition was fairly stable between May 2014 and July 2015. From July 2015 to April 2016 NDVI change indicated &lt;i&gt;Phragmites&lt;/i&gt; suffered a widespread decline in the live biomass proportion. &amp;nbsp;Between April and September 2016, most marsh remained unchanged from the earlier period or showed improvement; although there were pockets of continued decline scattered throughout the lower delta. From September 2016 to May 2017 a pronounced and widely exhibited decline in the condition of &lt;i&gt;Phragmites&lt;/i&gt; marsh again occurred throughout the lower delta. This final NDVI change mapping supported field observations of &lt;i&gt;Phragmites&lt;/i&gt; decline during the same period.&lt;/p&gt;</dc:description>
