Its NDVI is less than grass land. Seasonal marshes 132 NDVI changes between 0.1 Seasonal marshes(inland) 1321 0 and 0.5, and there is a Seasonal marshes(coastal) 1322 0 periodical change of NDVI value for the whole year. Sometimes NDVI is smaller than 0 when it is flood season.

Grass 23 NDVI changes between 0.3 Grass 23 20 and 0.6, it shows less fluctuation. Human-made cover or bare land 24 NDVI is less than 0.2 and has human-made cover or bare land 24 40 little changes for the whole year. Drylands 25 NDVI values increase and Drylands 25 80 decrease sharply for the whole year.
