Appendix 2: Risk probability, consequence and impact analysis

Probability assessment (defining the probability of the issue occurring)
Terms used to describe the probability of an event occurring are:
    * Likely: Event is known to occur or would be expected to occur
    * Occasional: Event may occur
    * Possible: Event would be unlikely to occur (evidence to suggest it is possible)
    * Unlikely: Event would occur rarely (uncommon but known to occur elsewhere)
    * Rare: Event would occur very rarely (in exceptional circumstances)
    * Remote: Chance of event occurring is so small it can be ignored in practical terms (never heard of but not impossible)

Consequence assessment (defining the consequences of the issue occurring)
Terms used to describe the severity of the expected impacts (level of significance) are shown in Table 15. These terms are used in the risk evaluation matrix for potential impacts shown in Figure 2.
Table 15. Levels of impact and their ecological consequences
Level          Ecological consequence
Negligible     Insignificant impacts to populations. Unlikely to be measurable against background variability. Interactions may be occurring, but it is unlikely that there would be any change outside of natural variation.
Low            Possibly detectable but little impact on population size and none on dynamics.
Moderate       Level of interaction/impact at maximum acceptable level. Long-term recruitment/dynamics not adversely affected.
High           Level of impact above maximum acceptable level. Would affect recruitment levels of the species or their capacity to increase in numbers.
Very High      Likely to cause local extinctions if continued.
Catastrophic   Local extinctions are imminent/immediate.
