I’ve just been onto the excellent Forestry Commission web pages about C. fraxinea (info and Q&A). It has a link to the European and Mediterranean Plant Protection Organization (EPPO) website. This has a good, if disturbing, alert list.
I do find it relieving that there are clearly caring and competent people in these organizations. I have absolute faith that the FC and Fera will do their best in – and quite possibly THE best for – this situation. I am glad that EPPO exists, and more power to it.
They have to work in the face of brash consumerism. It’s a hard job.
