Limitations
• Prioritization model for introduced species• Lack of information on invertebrates (invasiveness)• Shared data bases• Country lists of quarantine pests• Emphasis on economics rather than conservation

Perspective: The way forward• Key challenges• Invasive species• Stemming migration• Achieving community ‘buy in’• Securing and restoring key habitats
• Where the answers lie• On-going and increased commitment from stake
holders at all levels• Efficient implementation of Quarantine System• Appropriate PRA models
