Table 3. Five-point rating scale to define the potential threat magnitude.

Threat magnitude	Definition
Very high	The threat is likely to destroy or eliminate the species, or reduce its population by 71–100%
High	The threat is likely to seriously degrade/reduce the species or reduce its population by 31–70%
Medium	The threat is likely to moderately degrade/reduce the species or reduce its population by 11–30%
Low	The threat is likely to only slightly degrade/reduce the species or reduce its population by 1–10%
No threat	The threat is likely to not degrade/reduce the species or reduce its population by less than 1%
