Pathway evaluation and pest risk management in transport (PERMIT)

Home Research Pathway evaluation and pest risk management in transport (PERMIT)


Movements of Invasive Alien Species (IAS) globally by trade and human movement present severe and increasing risks of transfer of plant pests (principally invertebrates and plant pathogens) globally. Climate change adds further opportunities for pest establishment and impact, both by providing increased survival and growth opportunities for pests and, through environmental stresses, making trees more vulnerable to those pests.

In relation to ecosystem services and their longevity, forests are particularly vulnerable to IAS. In particular, multiple PATHWAYS for transfer of pests internationally are poorly characterised, leading to increasing transfer and establishment of new damaging organisms. The COST Action FP1002 PERMIT addresses this shortfall in knowledge and practice and will focus on reducing threats from exotic pests through promoting ENHANCED PATHWAY MANAGEMENT.

The general approach will be through analysis and shared experiences of the principal pathways for movement of forest pests. This will lead to an appraisal of potential generic procedures that could be applied to pathway management, ultimately leading to a “manage once, remove many” Systems Approach to maximise pest reduction and to influence future phytosanitary policy. It will deliver hard copy, electronic and workshop outputs and exchange of experiences through at least 4 Short Term Scientific Missions per year.


The project was divided into the following working groups:

  • Working Group 1: Pathway characterisation linked to pest movements and trade patterns
  • Working Group 2: Development of generic risk mitigation measures to reduce pest movements along pathways
  • Working Group 3: Analysis of the level of education and awareness of risks associated with different pathways
  • Working Group 4: Identification of research and data gathering needs.

Working groups in detail

Funders and partners

This programme was funded by the European Union – EU COST Action FP1002.

PERMIT currently had 24 COST countries and 8 non-COST institutions (from 6 countries) contributing to the Action.

Forest Research involvement


The project started in November 2010 and continued until November 2014.
