NASA Finds Cause of Florida Mangrove Forests Die-off

Mangroves are resilient trees tolerant of salt water and high wind and wave energy, which is why they can typically withstand hurricanes in tropical and subtropical environments. In 2017, NASA scientists noticed mangrove forest die-off in southern Florida after Hurricane Irma. Using NASA’s G-LiHT instrument and satellite data from Landsat, they learned that pooling, stagnant water was the cause.
