Cluster number1

Description of land cover

0 Area of no substantial ground-water evapotranspiration (unclassified)
1 Area dominated by submerged aquatic vegetation and open-water marsh; water above land surface
2 Area dominated by dense vegetation; forest or grass/shrub meadows; water table below land surface; soils moist to dry
3 Area dominated by dense to moderately dense vegetation; mature grasslands, intermittently flooded; water table at or near land surface; soils wet to moist
4 Area dominated by sparse vegetation; open grass and shrub lands; water table below land surface; soils dry
5 Area dominated by moist bare soil; vegetation very sparse; water table at or near land surface; soils wet to moist
6 Previously farmed field; vegetation sparse; water table below land surface; soils dry
7 Area of open water; reservoir or large spring pool
