Upland Hardwood Forests
Rich Wet-Dry Hardwood Forests
General Description This is the habitat associated with nutrient-rich, high pH soils that has the widest tolerance for moisture conditions, ranging from dry mafic and calcareous uplands to rich, wet alluvial forests. This habitat is widespread, with occurrences in all three of the state's physiographic provinces. Other habitats associated with rich soils occupy a narrower range of moisture conditions, although they can extensively intersect with this general habitat fairly extensively.

Abiotic Factors Geographic Regions: Lower Coastal Plain to High Mountains. USDA Hardiness Zones: 6-8. Landform: ridges, slopes, bottomlands, and wet flats. Slope Aspect: occurs on all slopes aspects as well as on ridges and flats. Soil Moisture: Dry to wet. Soil texture: loamy to alluvial. Soil pH: circumneutral. Soil Nutrient Content: rich in mafic or calcareous minerals.Microclimate: Warm and dry to cool and humid. Hydrological Features: springs and seeps are common, particularly at the interface between slopes and bottomlands. Flood Frequency: ridges and upper slopes usually never flood but lower slopes and bottomlands may flood several times per year. Flood Duration: hours to days in the bottomlands and lower slopes. Fire Frequency: occasional on ridges and upper slopes, rare in bottomlands Drought Frequency: occasional on upper slopes, rare in bottomlands. Ice Storm Damage: low to moderate. Wind Storm Damage: moderate. Insolation: canopies are well insolated, lower strata are deeply shaded.

Biotic Structure Vegetation Type: closed-canopy forest composed of broadleaf, deciduous trees. Strata: Subcanopy, shrub, and herb-layers are well developed. Shelter: Woody debris and leaf litter are plentiful except in flood channels or other areas frequently scoured by floods.
