General Description This habitat is defined by the presence of Nyssa species, which collectively, occupy a wide of habitat conditions: deeply flooded swamps in the case of Water Tupelo; blackwater floodlplains and depression ponds in the case of Swamp Tupelo; and dry uplands in the case of Blackgum.

Since each species of Nyssa occupies a different habitat type, none of them are determining species of this general habitat. Instead, the determining species are stenophagous herbivores that feed on all three species of Nyssa and consequently occur throughout the range of that genus.

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 hydric. Soil texture: sandy to loamy to alluvial to mucky. 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: permanently to never flooded. Flood Duration: nonexistent to permanent. Fire Frequency: common to rare. Drought Frequency: frequent to rare. Insolation: full sun to full shade

Biotic Structure Key Species species of Nyssa must be present Vegetation Type: closed-canopy forests, including swamp forests, to dry open woodlands. woody debris is plentiful but leaf-litter may be sparse to absent in floodplain examples

ENE = Expected Number of Extirpations (Sum of PE) = 0.00496
Average PE (ENE/Ner) = 0.00071
Habitat Risk Index = (Nar+Nv) x Average PE = 5 x 0.00071 = 0.00355
