The susceptibility of a species population to damage, or death, from an external factor. Intolerance is assessed relative to change in a specific factor.
|High||The species population is likely to be killed/destroyed by the factor under consideration.|
|Intermediate||Some individuals of the species may be killed/destroyed by the factor under consideration and the viability of a species population may be reduced.|
|Low||The species population will not be killed/destroyed by the factor under consideration. However, the viability of a species population will be reduced.|
|Tolerant||The factor does not have a detectable effect on survival or viability of a species.|
|Tolerant*||Population of a species may increase in abundance or biomass as a result of the factor.|
|Not relevant||This rating applies to species where the factor is not relevant because they are protected from the factor (for instance, through a burrowing habit), or can move away from the factor.|
