Healthy Meadow: Factors of a pristine meadow include: meadow hydrology, soils and vegetation and interdependent; diverse mosaic of habitat with wet meadow and riparian vegetation; surface flow from snowmelt; high water table; inundation during floods with sediment deposition and attenuated flood flows; subsurface flow of snowmelt; and percolation with groundwater recharge.
