Table 4.

Integrating measures of exposure (Table 2), sensitivity (Table 3) and range shift potential to assess overall level of risk. Formula indicates whether all measures were combined together or only two needed to be true (Exp—Exposure, Sen—Sensitivity, Range—Range shift potential)

Risk Level	Formula	Exposure	Sensitivity	Range shift
Low	Exp + (Sen OR Range)	1	Low (−)	High (+)
Low	Exp + Sen + Range	2	Low (−)	High (+)
Medium	Exp + (Sen OR Range)	2	Mid (0)–high (+)	Low (−)
Medium	Exp + Sen + Range	3	Low (−)–mid (0)	High (+)
Medium–high	Exp + (Sen OR Range)	3–4	High (+/++)	Low (−)
High	Exp + Sen + Range	3–4	High (+/++)	Low (−)
