Upland Hardwood Forests
General Mesic Hardwood Forests
General Description This habitat consists of hardwood forests with relatively cool micro-climates and high soil moisture. They occur across the state on north- and east-facing slopes that do not receive full insolation during the warmest part of the day. They also occur in ravines along streams and in the higher, infrequently flooded terraces along larger streams and rivers. In the Mountains, these conditions are generally present in all hardwood forests located above 4,000'.

This habitat is the most generalized of the mesic hardwood habitats, occurring across the state and associated with both loammy and sandy soils, and with moderately low to moderately high pH and soil nutrients.

Abiotic Factors Geographic Regions: Lower Coastal Plain to High Mountains. USDA Hardiness Zones: 6-8. Landform: slopes and bluffs over most of the state but also on ridges in the Mountains. Slope Aspect: north and east facing in the Piedmont and Coastal Plain but all aspects in the Mountains. Soil Moisture: Mesic. Soil texture: loamy, permitting burrowing by fossorial species; rocks are often present on the surface of slopes and in the mountains extensive areas of talus can be present. Soil pH: acidic to circumneutral. Soil Nutrient Content: nutrient poor to rich. Microclimate: Cool and humid. Hydrological Features: springs and seeps are common, particularly at the interface between slopes and bottomlands. Fire Frequency: very rare. Drought Frequency: uncommon to rare. 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 forests composed of broadleaf, deciduous trees over most of the state but with Eastern Hemlocks prominent in the Mountains . Strata: Subcanopy, shrub, and herb-layers well-defined but often sparse. Woody debris and leaf litter: logs and fallen branches are common; leaf litter can be plentiful, as under deciduous forests in general, but its build-up may be limited due to erosion and general downhill slippage on the steep slopes characteristic of this habitat
