BIP ‘Alien species in forest ecology’ – a global perspective on alien tree species facing climate change

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.
