Honey Locust Groves
General Description This habitat is defined by the Honey Locust. Determining species include Honey Locust itself, as well as its set of obligate herbivores.

The distribution and ecology of this group appears to be unique in North Carolina. Honey Locust is primarily a Midwestern species and its occurrence east of the Appalachians may be artificial, although of long-standing: European settlers planted it around their dwellings as well as out in pastures where livestock could forage on its seed pods. Most of the occurrences in North Carolina are found around old abandoned homesites -- sometimes deep in the woods -- or around the edges of old pastures.

In a few places in the state, virtually the entire fauna of Honey Locust herbivores has been found together, posing questions as to how these groups were assembled -- through separate dispersal from their original Midwestern range, through transport of larvae along with transplanted plants (unlikely if only seeds were transported), or from previously undiscovered native populations of the plants?

Nr = Number of Ranked Species = 10
Ner = Number of Extant, Ranked Species = 10
Nv = Number of Historic and Extirpated Species = 0
Nar = Number of Species at Risk of Extirpation (State rank > S5) = 10
Nss = Number of Secure Species (State Rank = S5) = 0
Pss = Proportion of Secure Species (Nss/Ner) = 0.00000
ENE = Expected Number of Extirpations (Sum of PE) = 0.16118
Average PE (ENE/Ner) = 0.01612
Habitat Risk Index = (Nar+Nv) x Average PE = 10 x 0.01612 = 0.1612
