Prevention
What is Prevention?
– Minimizing the risk of moving alien species to
countries or ecosystems where they may become
invasive
Why is Prevention important?
• IAS are a serious problem
– urgent attention to the IAS problem is needed
– prevention is better that the cure
– prevention is most cost-effective (cheapest!)
IAS are a serious problem
• You have seen the impacts IAS have on the
– economy
– environment
– human health
Urgent attention to the IAS
problem is needed
• The risks of transferring IAS to new locations
increases as more people are travelling and
amount of freight is increasing.

Prevention is better that the cure
• Once an IAS has established in a new
location it can be very difficult, expensive and
environmentally damaging to remove.
Prevention is most cost-effective
(cheapest!)
• The costs of an efficient and effective
prevention system are far less than those of
dealing with established IAS populations.
Prevention is the first and best line of defence
Where can Prevention be applied?
• Pre-border (before it leaves a country)
• At the border (before it enters a country)
• Post-border (within a country)
Principles of IAS Prevention
(see workbook)
Approaches and Tools to IAS
Prevention
• Legal and Institutional Requirements
• Coordination
• Collating and Sharing Information
• Education and Awareness
Approaches and Tools to IAS
Prevention
• Risk Analysis
• Authorization Procedures
• Species List
• Quarantine and Border Control
• Treatment
Legal and Institutional
requirements
• These include:
– International conventions
– Treaties
– National laws
– Internal policies
– Protocols
Coordination
• Coordination at international, regional and
local levels is essential to develop solutions
to common problems.
Collating and Sharing Information
• Information needs to be collected
collated to identify potential IAS.
and
• Countries and regions should share
information that may impact their neighbors.
Education and Awareness
• Public education is critical in the fight against
IAS because human activity is the main
cause of the problem.

Risk Analysis
• Risk analysis is the process of identifying
unwanted species introductions, their
associated impacts and management
strategies.
Risk Analysis
• Applied to species or pathways
• Three main components:
– risk assessment
– risk management
– risk communication
Risk assessment steps
• 1. Identify the proposed species or pathways
Then assess:
• 2. Likelihood of IAS being introduced
• 3. Likelihood of it establishing
• 4. Consequences of establishment
Continued…
Risk assessment steps
• 5. Level of risk posed without management
• 6. Feasibility of managing spread
• 7. Feasibility of managing incursions
• 8. Any residual threat posed
Risk Management
• From the assessment decide whether risk
management is required and the treatments
required.
Risk Communication
• Clearly communicate to stakeholders
information on risk assessment and
management options.
• This leads to better understanding and
decisions
Authorization Procedures
• Permits and licences are important tools for
controlling the movement of alien species
between and within countries.
Species List
• To filter the intentional introduction of
invasive species, a list system should be
applied:
– Black list = bad
– White list = good
– Grey list = unknown
Quarantine and Border Control
• It is vital to improve procedures to intercept
IAS at the border and prevent their spread
within a country or ecosystem.
Pre border
•
•
•
•
•
Certification
Inspection
IAS proof packaging
Treatment
Pre-quarantine for live plants and animals
Border
•
•
•
•
Certification
Treatment
Visual inspection
Remote inspection
- x-ray
- sniffer dogs
- cameras
• Post-entry quarantine for live
plants and animals
Airport quarantine bin
Post border
• Public awareness
• Surveillance
- active trapping
- public surveillance
 Pre-planned response programmes
 Pre-planned management programmes
Treatment
• Many commodities need to be treated to
prevent IAS being introduced.
Summary
• Prevention is the first, best and cheapest line of
defence.
• Prevention approaches and tools can be
implemented either:
- Pre-border
- Border
- Post-border
• Different organisation and groups of people need
education to aid in preventing IAS.
• A comprehensive risk analysis on any species is
essential.
