Forestry Commission are urging woodland managers, landowners, the forest industry and tree nurseries to remain vigilant after the tree pathogen Phytophthora pluvialis was found in a woodland in Cornwall.   This is the first reported finding of P. pluvialis in Europe. It was found to be affecting mature western hemlock and Douglas-fir trees, but it can also affect tanoak and several pine species.  Any suspected findings should be reported to TreeAlert.  Visit the GOV.UK website for further guidance and information.
