Dear Forest Pathologists, As you know, the International Congress of Plant Pathology (ICPP2023, https://www.icpp2023.org/) will take place in the beautiful city of Lyon, France, from August 20 to 25, 2023. During the congress, there will be at least 6 concurrent sessions devoted to forest or tree pathology. On behalf of the Forest Pathology Subject Matter Committee of the International Society of Plant Pathology (ISPP) and of IUFRO Division 7, Tod Ramsfield kindly asked me to organize a Forest Pathology Field ahead of the conference, as is the case at every ICPP. Together with three colleagues from the French Department of Forest Health (DSF), we have put together an exciting program for this excursion. The field trip will take place on *Saturday, August 19*, all day from 8am to 8pm. We will go to the Chautagne Forest, near the Bourget Lake in the Alps, about 2 hours by bus from Lyon, to discover several forest diseases (see attached file). The number of participants to this field trip will be *strictly limited to 50 persons* (1 bus) on a first come first served basis. Therefore, I would advise those interested *not to wait too long to register*. Registration for the field trip is already open and can be done at the same time as registration for ICPP by choosing among the satellite events (https://www.icpp2023.org/registration) The fee for the field trip is the same as for all other satellite events (90€ per person, including transportation, coffee break, lunch at restaurant, and visit of the Hautecombe Abbey). In addition, I would like to have an idea of how many forest pathologists would be interested in participating in this field trip. For this, please answer this very short survey (3 questions): https://evento.renater.fr/survey/icpp2023-forest-pathology-field-trip-2bl6u… Please note that this survey is purely indicative and does not replace your registration on the ICPP2023 website. I look forward to meeting many of you in Lyon in August!
