Problematic Hydrophytic Vegetation� (Explain)
'Indicators of hydric soil and wetland hydrology must be
present, unless disturbed or problematic.
Definitions of Four Vegetation Strata:
Tree - Woody plants, excluding vines, 3 in. (7.6 cm) or
more in diameter at breast height (DBH), regardless of
height.
Sapling/Shrub - Woody plants, excluding vines, less
than 3 in. DBH and greater than or equal to 3.28 ft
(1 m) tall.
Herb - All herbaceous (non-woody) plants, regardless
of size, and woody plants less than 3.28 ft tall.
Woody Vine - All woody vines greater than 3.28 ft in
height.
