Pine Wood Nematode

This web page displays information related to the pine wood nematode relevant to the forest sector.



Following a request for this web page from the Pine Wood Nematode Group, the page was initiated by the former EFIATLANTIC, the EFI Atlantic Regional Office, in the framework of the FORRISK project.

The Pine Wood Nematode Group gathers people interested in a continuous exchange of information on this topic in order to be able to inform and support administrative bodies, scientists and stakeholders about Pine wood nematode risks and contribute to its mitigation.

The formation of this group was an outcome of Nematode Day, an event held in Spain in 2011, during which decision makers and forest sector organisations were provided with up-to-date information about the Pine wood nematode problem in the Iberian Peninsula.


Legal Framework

Many EU decisions refer to the Pine wood nematode; some of them were summarised during the Nematode Day in 2011 and in a summary produced by UNAC.

  • Directive 2000/29/EC on protective measures against the introduction into the Community of organisms harmful to plants or plant products and against their spread within the Community. This directive defines all the treatments required on wood products coming from Portugal in annexa and phytosanitary documents required for at risk materials.
  • Decision 2006/133/EC requiring Member States to temporarily take additional measures against the dissemination of Bursaphelenchus xylophilus (Steiner et Buhrer) Nickle et al . (the pine wood nematode) regarding areas in Portugal, other than those in which it is known not to occur. This decision was abrogated in 2012 (including 2009 modifications).
  • Decision 2012/535/EU on emergency measures to prevent the spread within the Union of Bursaphelenchus xylophilus (Steiner et Buhrer) Nickle et al. (the pine wood nematode).
  • Decision 2015/226/EU on emergency measures to prevent the spread within the Union of Bursaphelenchus xylophilus (Steiner et Buhrer) Nickle et al . (the pine wood nematode). In particular it amends the definition of susceptible wood. This is the new decision in force.

The reference norm for wood product treatment is the one defined by the FAO in its document International Standards for Phytosanitary Measures (2005):

  • ISPM n°15  Guidelines for regulating wood packaging material in international trade (page 173).


Ongoing European Actions


Legal actions

  • Audits

DG Sanco (Directorate General for Health and Consumer Affairs) regularly conducts audits to ensure that EU regulation is applied properly, especially in the buffer zone between Portugal and Spain:

The three latest EU audit reports are available for download:

Portugal: 2014, 2013, 2012
Spain: 2014, 2012, 2011

For older reports consult the European Commission audit report web page.

Research actions

  • IUFRO Working Party 7.02.10 - Pine Wilt Disease: an information exchange to advance understanding of PWD as an insect-borne infectious challenge to pine trees and pine ecosystems and to advance control strategies and tactics. 
  • PHRAME project (Plant Health Risk and Monitoring Evaluation): QLK5-CT-2002-00672: Development of improved pest risk analysis techniques for quarantine pests, using pinewood nematode, Bursaphelenchus xylophilus, in Portugal as a model system
  • REPHRAME project: Research Extending Plant Health Risk and Monitoring Evaluation. At the heart of the REPHRAME project is the development of a simple web-based interface Pine Wood Nematode Tool Kit (PTK) to provide analysed data from the project as well as a raft of new practical advice, new and improved methodologies available for tackling the pest.
