Join the largest event in Poland dedicated to tree diagnosis and biology. Speakers from Poland and abroad, workshops and discussions – and a common bonfire at the end! This is already the sixth edition of the congress bringing together specialists in arboriculture and dendrology.
This year, the congress will consist of a conference day and a day dedicated to workshops and panel discussions. The programme will be updated on a regular basis.
All lectures will be translated into Polish and English.













As part of KDD 2026, we are proposing a new type of activity for Congress participants. Those wishing to share ideas, statements or problems can submit a topic and invite other Congress participants to the discussion in parallel short sessions.
You are welcome to submit topics and show them to an interested small group and discuss. The form is free – a presentation in the Hall, an electronic or printed poster, a drawing or simply a live speech, if you prefer a mini workshop with an exchange of ideas, there is room for that too. Recommended speaking time is 10 minutes + up to 20 minutes of discussion. Participants (including speakers outside of their talk) are welcome to move around the auditorium and participate in topics of their choice. We anticipate space for up to 12 speeches in the form of presentations (2-3 in parallel) and up to 20 (4-5 in parallel) in other forms (e.g. poster, speech, discussion).
For those who register with TSC, we offer a discount on the TAC participation fee.
This year, the Congress will be held at the Museum of the Second World War in Gdańsk. In addition to its important scientific and historical value, this venue is also a modern conference complex.
