The Environmental Weed Risk Assessment Protocol
The protocol is divided into three sections:
- Invasiveness
- Impacts
- Distribution.
Each section has a series of questions that generate a score depending on the response given. The scores for invasiveness and impacts are adjusted to range from 0 to 10 (potential distribution is already a score ranging between 0 and 10).
A final weed risk score is then calculated by multiplying the adjusted scores for each section, which can then be used to compare weed risk with other species.
