General Shrublands
General Rosaceous Thickets
General Description The defining factor of this habitat is the presence of shrubby or small tree species in the Rose family, including Cherries, Plums, Crab Apples, Hawthorns, and Serviceberries. Most of these species grow along forest edges and can be components of successional habitats; some are shade tolerant and grow in the understory of hardwood forests.

This particular habitat is fairly generalized, occupying a wide range of moisture regimes and soil types. It occurs widely across the state and is found in at least two of the state's physiographic provinces.

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 species belonging to the Rosaceae are a requirement Vegetation Type: shrublands 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 shrublands

Nr = Number of Ranked Species = 57
Ner = Number of Extant, Ranked Species = 55
Nv = Number of Historic and Extirpated Species = 2
Nar = Number of Species at Risk of Extirpation (State rank > S5) = 45
Nss = Number of Secure Species (State Rank = S5) = 10
Pss = Proportion of Secure Species (Nss/Ner) = 0.18182
ENE = Expected Number of Extirpations (Sum of PE) = 0.56600
Average PE (ENE/Ner) = 0.01029
Habitat Risk Index = (Nar+Nv) x Average PE = 47 x 0.01029 = 0.48363

Estimated Risk to the Determining Species Two species are considered historic and probably extirpated. Sphinx drupiferum is known from only three museum specimens, all collected in the early part of the last century. Prunus susquehanae, like S. drupiferum, is primarily a northern species known in North Carolina only from very old herbarium specimens. Two additional plants are ranked as S1 and two others as S2. The Average PE for this habitat is equivalent to a State Rank of S3 (nearly S2).

Estimated Risk to the Co-evolved Species Groups
Estimated Security of the Habitat Ten species in this habitat are considered secure in North Carolina. The Proportion of Secure Species, however, is fairly low at just 18%. This may reflect changes in agricultural practices to more "clean" farming, which utilizes more land at the expense of the successional habitats that were once widespread when fields were allowed to go fallow.

Index of Habitat Imperilment The combination of a fairly high value of ENE, a low value of PSS, and the presence of two SH species gives this habitat a fairly high HRI value. Although usually overlooked as a conservation priority, this successional habitat appears to be declining and needs to be monitored at the very least.
