Distribution Map

Efforts are currently underway to map the extent of the Phragmites die-offs in the delta and coastal Louisiana. Analysis of satellite imagery by the US Army Corps of Engineers suggests die-offs may have begun earlier than 2016, and comparison of NDVI between years gives some indication of the severity of the die-offs in the delta.

A census has also been taken of Phragmites populations across the state to assess the extent of the invasion by the scale. As of fall 2017, the scale appears to be wide spread among the southeastern parishes, but completely absent from western coastal Louisiana.
