The COST Action UB3Guard successfully hosted its Training School: "The Social Dimensions of Urban Tree Biosecurity," held from October 7–10, 2025, at Forest Research, Forest Research Station, Roslin, Scotland.

This focused four-day training school provided an invaluable opportunity for participants to advance their expertise in the crucial social aspects of tree health. Attendees included PhD students, early-career researchers, and professionals involved in urban tree management and biosecurity.

Key Outcomes of the Training School

The rigorous programme was designed to both inform and equip participants with practical skills, successfully covering the following core areas:

• Current Social Research: Participants gained in-depth knowledge of the latest social research findings relevant to urban tree health.
