HydricWet, plants periodically or often inundated by water.
HydricWet, plants periodically or often inundated by water. Water removed so slowly that water table is at or above soil surface all year; gleyed mineral or organic soils.Sub-hydricWater removed slowly enough to keep water table at or near surface for most of year; gleyed mineral or organic soils; permanent seepage < 30 cm below surface.HygricWater removed slowly enough to keep soil wet for most of growing season; permanent seepage and mottling; gleyed (greenish-blue-grey) colors common.Sub-hygricWater removed slowly enough to keep soil wet for a significant part of growing season; some temporary seepage and possibly mottling below 20 cm.MesicMoist, adequate soil moisture retention year-round. Water removed somewhat slowly in relation to supply; soil may remain moist for a significant, but sometimes short period of the year. Available soil moisture reflects climatic.Sub-mesicWater removed readily in relation to supply; water available for moderately short periods following precipitation.Sub-xericMoist to dry, seasonally moist, periodically dry. Water removed rapidly in relation to supply; soil is moist for short periods following precipitation.XericDry and drought resistant, little moisture retention, excessively drained — May have multiple assignments. Water removed very rapidly in relation to supply; soil is moist for brief periods following precipitation.Very xericWater removed extremely rapidly in relation to supply; soil is moist for a negligible time after precipitation.
