Sweetgum Groves and Forests
General Description The presence of Sweetgum is the defining factor of this habitat. Along with Red Maple, Persimmon, and pines, Sweetgum is an important tree species in old-field succession as it occurs across most of the state, showing up at the end of the open field stage. As with the other species mentioned, Sweetgums can persist as the forest grows up around them.

Determining Species include Sweetgum itself, as well as its monophagous herbivores.


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: sandy to loamy to alluvial. Soil pH: circumneutral to acidic. Soil Nutrient Content: rich to poor. Microclimate: Warm to cool; humid to dry. Hydrological Features: surface waters are common to scarce. Flood Frequency: transiently to never flooded. Flood Duration: nonexistent to transient. Fire Frequency: common to rare. Drought Frequency: frequent to rare. Insolation: full sun to full shade

Biotic Structure Key Species: Sweetgum must be present. Vegetation Type: open fields to closed-canopy forests; all stages of natural succession are included. Woody debris and leaf litter are plentiful in forested examples but sparse in successional habitats

Ner = Number of Extant, Ranked Species = 8
Nv = Number of Historic and Extirpated Species = 0
Nar = Number of Species at Risk of Extirpation (State rank > S5) = 6
Nss = Number of Secure Species (State Rank = S5) = 2
Pss = Proportion of Secure Species (Nss/Ner) = 0.25000
ENE = Expected Number of Extirpations (Sum of PE) = 0.00802
Average PE (ENE/Ner) = 0.00100
Habitat Risk Index = (Nar+Nv) x Average PE = 6 x 0.001 = 0.006
