As Research Fellow, Hugh continues to work on aspects of research into the health of trees, with particular emphasis on national and international phytosanitary and biosecurity issues. He also works on the integrated management of tree pests, especially using biological control agents. He provides expert consultancy on a range of issues, especially international biosecurity risk assessment and management.
Hugh currently provides the science lead on a Euphresco project dealing with risks to Europe from emerald ash borer and bronze birch borer. See https://www.forestresearch.gov.uk/research/prepsys/. He also works with INIAV in Portugal on risks to pine forests there from pinewood nematode, Bursaphelenchus xylophilus.
He previously coordinated two major projects, part funded by the EU:
- Interreg IVA Ireland-Wales programme: IMPACT - Integrated Management of forest Pests Addressing Climate Trends.
Assessment of current and future forest insect threats and development of biological control solutions. Partnered with National University of Ireland, Maynooth and Department of Biology, Swansea University.
- Framework 7: REPHRAME – Research Extending Plant Health Risk And Management Evaluation.
This project dealt with the threats posed to Europe by pine wood nematode, Bursaphelenchus xylophilus and involved 11 partners in 8 countries (Austria, China, France, Germany, Norway, Portugal (2), Spain (2) and UK (2). http://www.rephrame.eu/
Hugh also chaired the EU COST Action FP1002 (PERMIT – Pathway Evaluation and pest Risk Management In Transport) involving 25 COST and 7 non-COST countries. This project examined the many pathways on which pests and pathogens can move internationally and assessed how to manage these pathways to reduce risks.
