Research: City trees 26. October 2020 Kevin-Buri Diseases of city trees, Step 2 Research, Team Zurich M18a, IDAF20 (0) Neophyte: We have planned to visit a booth at the marketplace in Oerlikon on October 24, 2020. The host "Natur liegt Nahe" would have a booth where they would educate about neophytes. We have prepared questions for the excursion. I went to the Oerlikon marketplace on October 24, 2020, and gathered information and sources. I also interviewed Julia Fürst, a master student in "Biodiversity and Conservation Biology" and "Nature Conservation Biology" who works in the federal research institute in Birmensdorf. She answered our questions. She also gave me more basic information about the problem. (Work in progress)
