Nr = Number of Ranked Species = 5
Ner = Number of Extant, Ranked Species = 5
Nv = Number of Historic and Extirpated Species = 0
Nar = Number of Species at Risk of Extirpation (State rank > S5) = 3
Nss = Number of Secure Species (State Rank = S5) = 2
Pss = Proportion of Secure Species (Nss/Ner) = 0.40000
ENE = Expected Number of Extirpations (Sum of PE) = 0.11371
Average PE (ENE/Ner) = 0.02274
Habitat Risk Index = (Nar+Nv) x Average PE = 3 x 0.02274 = 0.06822
