Risk Assessment and Prioritisation for Invasive Species
John Kelly
Overview
• Aims of RA process • Overview of methodology • Preliminary results• Pathway and vector management - which are
already covered by COP/Legislation/Education and awareness, which are not being managed at all?
• Implications for Ireland - species, pathways, new challenges
• What actions are needed? ISI plans, gaps and needs
• Next steps
What is Invasive Species Risk Assessment?
High RiskDefine Management
Priorities
ISAPs
Prevent further invasion, if appropriate
Recorded species
Risk Assessment
Medium Risk
Define Management Priorities
ISAPs/Guidance
Prevent further invasion, if appropriate
Low Risk
Re-evaluate in future, if required
High RiskDevelop exclusion
strategies
Monitor for incursion
Develop response capabilities
Medium Risk
Consider exclusion strategies
Monitor for incursion
Develop response capabilities
Potential species
Low Risk
Re-evaluate in future, if required

Uncertainty: Traffic Light System
Red – High degree of uncertainty in the assessment. Very little documented evidence to support assessment.
Amber – Reasonable degree of confidence but more reliance on expert opinion.
Green – High degree of confidence in in the assessment. Reliance on documented evidence.
Uncertain – Probable – Expert Opinion - Documented

Unintentional Pathway/Vectors for High and Medium Risk Freshwater Species
Pathways of Introduction Freshwater Vectors of Spread
Other emerging trends
• Pet species• Unregulated release is still an issue• Biosecurity• Guidance on keeping non-natives• Engagement with the Early Warning Network
A lot done, more to do
• Codes of Practice– Water Users– Aquaculture– Horticulture– Marina Operators
• Invasive Species Action Plans• Promote existing and forthcoming legislative
provisions– All stakeholders!!
Public Awareness
Be Pet Wise
Further considerations
• What species are coming into Ireland and Northern Ireland?– No central database– No central organisation providing guidance
• Constantly changingRecorded species Potential species
• Climate change• No clear ‘home’ for species found in houses
Next Steps
• Finalise and Review all Risk Assessments• Publish results• Prevent incursion of high risk species• Promote Biosecurity• Early Warning
– Recording
