Tree Health Field Support Officer
From April 2012, he has been responsible for providing field support for any current Plant Health issues.
Nick joined FR in 1974 as an assistant scientific officer in the entomology branch, working at Alice Holt.
He moved to Ludlow in 1986 to run the field-station there, mainly working on the biological control of Dendroctonus micans using the specific predator Rhizophagus grandis. During 1990 he was seconded to Forestry Canada to work on potential insect vectors of the pine wood nematode.
Plant health work with emphasis on surveys for non-native insect pests.

News of a recent unwelcome discovery and how ‘citizen science’ can play an important role in surveying and identification. An overview of the 2015 discoveries of Dryocosmus kuriphilus (Oriental chestnut gall wasp; OCGW) in European sweet chestnut (Castanea sativa) trees in Farningham Woods, Kent and St Albans, Hertfordshire, was published in Quarterly Journal of Forestry. It […]
