Upland Hardwood Forests
Locust Groves and Thickets
General Description This habitat consists of groves of Black Locust, including rich, mesic coves in the Mountains -- probably representing their original habitats in North Carolina -- as well as disturbed areas in the Piedmont, where they appear to have spread since Europeans moved into the area. While Black Locust grows in some of the disturbed habitats occupied by Honey Locust, their ranges and habitats do not coincide in the Mountains; each is treated within a separate habitat type.

Nr = Number of Ranked Species = 16
Ner = Number of Extant, Ranked Species = 16
Nv = Number of Historic and Extirpated Species = 0
Nar = Number of Species at Risk of Extirpation (State rank > S5) = 14
Nss = Number of Secure Species (State Rank = S5) = 2
Pss = Proportion of Secure Species (Nss/Ner) = 0.12500
ENE = Expected Number of Extirpations (Sum of PE) = 0.01476
Average PE (ENE/Ner) = 0.00092
Habitat Risk Index = (Nar+Nv) x Average PE = 14 x 0.00092 = 0.01288
