Nr = Number of Ranked Species = 5
Ner = Number of Extant, Ranked Species = 4
Nv = Number of Historic and Extirpated Species = 1
Nar = Number of Species at Risk of Extirpation (State rank > S5) = 4
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) = 1.00397
Average PE (ENE/Ner) = 0.25099
Habitat Risk Index = (Nar+Nv) x Average PE = 5 x 0.25099 = 1.25495
