A global perspective on alien tree species facing climate change
Alien tree species – threat or opportunity?
Discussions centred on the role of alien (introduced) tree and shrub species in habitats where humans have introduced them, intentionally or accidentally. This topic has been controversial for years. On one hand, these species are often blamed for displacing native flora; on the other hand, their rapid growth, resilience, and potential benefits in climate change are emphasised. It is important to note that not all alien species are invasive, and some can benefit our ecosystems.

Participants in the program had the opportunity to learn about:
- The biological basis and global consequences of alien species.
- The growth potential of introduced tree species.
- The regenerative capacity of alien species during the study of younger generations.
- The impact of introduced animals on native ecosystems.
- Approaches and methods for managing these issues in protected and regulated areas.



The described BIP was implemented at the Faculty of Forestry of the Warsaw University of Life Sciences (SGGW), the supervisors were Dr. Wojciech Kędziora and Dr. Karol Bronisz, while the teaching staff were: Dr. Katarzyna Marciszewska, Dr. Artur Obidziński, Dr. Szymon Bijak, Dr. Dagny Krauze-Gryz and Dr. Karolina Jasińska. Students had the opportunity to listen to lectures by foreign professors: Manuela Abelho from Coimbra in Portugal and Kelly Marion from Liège in Belgium.
