Invasion meltdowns in a biodiversity hotspot?
The Ukrainian Carpathian Mountains are home to Europe’s last great wilderness areas and to the greatest remaining old-growth and virgin forests. Pristine habitats at higher elevations, including old-growth forests, are however experiencing increased levels of invasion by alien plant species established for over a century in the adjacent lowlands. Under climate change, flooding is projected to become more frequent in the Carpathians, while increasing pressures from forestry and tourism are altering habitats, including in protected areas. Funded by a BES Large Grant, we have jumpstarted a long-term monitoring project to understand what drives successful multiple invasion, in particular how demographic traits (dispersal, reproduction, growth), and interactions among invaders and native species may affect establishment of invaders under global change.
Research questions
- What is the role of flooding in promoting the establishment of stable local populations of multiple invaders?
- Are interactions among invaders exacerbating the effect of human pressures and natural disturbances on multiple-invasion?
- What is the relative importance of species demographic traits on successful invasion?
- How important are interactions of biotic and abiotic effects in future invasion dynamics?

IMPORTANT UPDATE
Due to the invasion of Ukraine by Russian forces, causing great human suffering, our project will no ahead as scheduled, and the bulk of the work will be postponed to 2023. Although the Carpathian Mountains are not direct targets of attacks, most people there, including my collaborators from Danube Carpathian Programme, are largely focusing on humanitarian work.
