1 National Wetlands Research Center Marsh Dieback Syndrome (MaDS) Signature Key

2 National Wetlands Research Center Marsh Dieback Syndrome (MaDS) Signature Key The objective of this signature key is to provide a consistent method for photointerpreters to delineate important features of healthy and affected marsh. This key will assist the user in understanding marsh classification using high-altitude color infrared photography as applied to the Marsh Dieback Syndrome. The process of developing a key iterates between field observations and laboratory analysis of the photography. Ground level field observations were carried-out primarily during the winter of 2001 with additional observations made at other times. Ongoing oblique, low- altitude monthly aerial observations have been conducted continuously since the summer of 2000. Whenever possible, the photos in this signature key refer to the same dates and locations in order to provide consistency across the scale of photography.
