Upland Hardwood Forests
General Oak-Hickory Forests
No image for this habitat.
General Description This habitat comprises all forests that contain species of oaks or hickories. This general category spans a wide range of environmental conditions, from mesic, high elevation forests containing North Red Oaks, to hot, dry maritime forests on the Barrier Islands that support Live Oaks. Both closed-canopy stands are included as well as relative open woodlands; stands growing on uplands are represented as well as those growing in bottomlands or even swamps. No distinction is made relative to soil nutrients or pH.

No single species of oak or hickory spans this entire range. Consequently, the trees that are the key feature of this habitat are themselves members of habitats to which they show much higher individual fidelity. The Determining Species of this habitat are instead primarily stenophagous herbivores that specialize on oak or hickories at the generic level. Additionally included are a few species of mammals that are dependent on acorns and/or hickory nuts for a large part of their diet. Although less specific than the relationship between the herbivores and their host species, nut feeding species also belong to a long-co-evolved relationship with their food plants, serving as major dispersers of the trees' seeds.

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; more rarely hydric. Soil texture: loamy, sandy, to alluvial. Soil pH: acidic to circumneutral. Soil Nutrient Content: rich to relatively poor.Microclimate: Warm and dry to cool and humid. Hydrological Features: springs, seeps, and streams are common; some examples occur along river shorelines 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; permanent in the swamps occupied by Overcup Oak Fire Frequency: frequent in the sandhills but rare in the bottomlands and mesic slopes. Drought Frequency: occasional on upper slopes, rare in bottomlands. Ice Storm Damage: low to moderate. Wind Storm Damage: moderate. Insolation: most Maples are tolerant of shade and Red Maple in particular is also tolerant of sun, being a common pioneering species in old field succession.

Biotic Structure Key Species one or mores species of Quercus or Carya must be present Vegetation Type: open woodlands or closed-canopy forests. Strata: sparse to well-developed. Shelter: woody debris and leaf litter are generally plentiful

Nr = Number of Ranked Species = 107
Ner = Number of Extant, Ranked Species = 105
Nv = Number of Historic and Extirpated Species = 0
Nar = Number of Species at Risk of Extirpation (State rank > S5) = 74
Nss = Number of Secure Species (State Rank = S5) = 31
Pss = Proportion of Secure Species (Nss/Ner) = 0.29524
ENE = Expected Number of Extirpations (Sum of PE) = 0.36828

Habitat Risk Index = (Nar+Nv) x Average PE = 74 x 0.00351 = 0.25974

Estimated Risk to the Determining Species Several leaf-mining moths in this habitat have not received much attention in biodiversity surveys and have uncertain State Ranks. Two are known only from historic records but are assigned a rank here of SHS1, indicating some doubt about the status of SH; this rank is not assigned a PE value in this analysis. One other species is ranked as S1S2, based on a single recent record for this species in the state, and four others are ranked as S1S3. All other species in this habitat are ranked lower than S2. The Average PE is equivalent to a State Rank of S3, indicating a moderate level of conservation concern.

Estimated Risk to the Co-evolved Species Groups
Estimated Security of the Habitat Thirty-one species in this habitat are considered secure in North Carolina. The Proportion of Secure Species is 30%, which is moderately high. These relatively high values reflect the fact that Oak-Hickory forests are still widespread across the state and are represented by large blocks of habitat or well-connected smaller tracts.

Index of Habitat Imperilment Although the ENE value is low and the PSS value moderately high, the large number of species in this habitat gives it a moderately high HRI value. Although generally not composed of species having a high degree of conservation concern, the sheer number of species included as Determining Species of this habitat gives it a moderately high priority for conservation.
