Figure 4

Figure 4. Graph showing normalized difference vegetation index (NDVI) trajectories of Phragmites australis marsh sites in or near the U.S. Fish and Wildlife Service Delta National Wildlife Refuge. Each point on the trajectory plot represents the NDVI mean and standard deviation at each site at times of image collections (see “Methods” section for details). Colors are used to distinguish site trajectories. See fig. 3A and table 2 for site locations.
