The overall uncertainty score is calculated by adding all the section uncertainty scores and then dividing this by the number of sections (six).
Alternatively, to calculate manually, record the percentage uncertainty scores from the Weed risk uncertainty score and Feasibility of coordinated control uncertainty score below and then divide by six.
Section | Adjusted uncertainty score (Percentage uncertainty) |
---|---|
Invasiveness | |
Impacts | |
Potential distribution | |
Control costs | |
Persistence | |
Current Distribution | |
=(sum of adjusted uncertainty scores above)/6 (round to nearest whole number) |
The following levels of overall uncertainty need to be considered before submitting assessments. Assessments submitted with levels of overall uncertainty exceeding 15% will generally be returned to the assessor/s for further research.
Overall uncertainty level | Response needed |
---|---|
<15% | Submit assessment (ensure all information sources have been attached) |
15-30% | Revisit existing literature and source new literature before submitting assessment (contact NSW DPI staff for other possible information sources) |
>30% | Do not submit assessment (contact NSW DPI regional staff for help in locating information) |
Potential conflicts of interest exist when plants are considered as weeds in one situation but of economic use in another situation. Such conflicts of interest need careful consideration including consultation between all stakeholders.
This section looks at any other positive impacts a weedy plant may have. Note that some positive impacts on environmental health have already been considered in Question 6 in the Impacts section. These should be noted here as text with any references included. If needed, NSW DPI will make a separate assessment of the positive benefits of a species. That separate assessment will include appropriate consultation.
Conflicts of interest may arise when plants used for human or livestock food, pollen and nectar sources, for timber, herbal medicine, gardening and landscaping, as aquatic/aquaria species, for shelter and amenity, for soil conservation and revegetation, or for turf, escape cultivation and become weedy. Examples of potential conflicts of interest include:
There are likely to be a large number of other examples that have not been mentioned under each of these categories, and perhaps other categories that have not been mentioned above.
It is important that any positive benefits are fully considered in the WRM system and not dismissed out of hand.
Are there any other positive impacts the species may have? | |

List any stakeholders consulted in regards to this question below and the outcomes of these discussions.

This section allows the assessor/s the opportunity to offer further comments they feel could help support the assessment. Assessors are invited to provide comments in the assessment form and to attach further comments and documents if necessary. It is not compulsory to offer comments nor is it compulsory to offer sources of information in this section.
Assessors are asked to answer all questions before offering comments. This section therefore provides the opportunity for assessors to add information on areas that they feel have not been covered by the questions. This information may be of an economic, environmental or social nature and may include positive or negative aspects. For example comments may be offered on:
Positive impacts of the species should be noted in the Positive impacts section.
If needed, NSW DPI will make a separate assessment of the comments offered in this section. This assessment may include appropriate consultation.
The NSW WRM system has drawn on information contained in a number of sources, in particular the National Post-Border Weed Risk Management Protocols (Virtue et al. 2006). Acknowledgement is made of all contributors to that document.
The wording used in this document has been drawn extensively from the South Australian Weed Risk Management Guide (Virtue 2004) developed by the Department of Water, Land and Biodiversity Conservation. Particular acknowledgement is made of Dr John Virtue.
Useful additions to the wording have also been drawn from the Northern Territory Weed Risk Management system which is a joint Charles Darwin University and Northern Territory Government initiative. Particular acknowledgement of Dr Samantha Setterfield and Ms Natalie Rossiter of Charles Darwin University and Dr Keith Ferdinands of the Northern Territory Department of Natural Department of Natural Resources, Environment, The Arts and Sport is made.
Acknowledgment is made of the assistance, suggestions and comments received from NSW DPI and NSW local government staff.
