Assisted migration of threatened plant species

Project Description

Objective

As climate warms, many mountain species are forced to move uphill where temperatures are cooler. But some cannot shift their distribution quickly enough to keep pace with their changing habitats. Without help, they risk disappearing. This project tests “assisted migration” – relocating threatened plants to areas where conditions are, or soon will be, suitable. Researchers monitor candidate species, refine propagation techniques, and carry out experimental plantings at restoration sites. Researchers, practitioners and authorities work together to agree on when assisted migration is appropriate. The result will be practical guidelines and a toolbox that make the approach usable across Switzerland.

Relevance

Assisted migration has been debated for decades and remains controversial. Yet as climate change accelerates, it may become unavoidable. By providing scientific evidence, practical guidelines, and an open-access toolbox, this project builds the foundation for policy and practice. Beyond safeguarding alpine plants, it contributes to global debates on conservation in a warming world and helps Switzerland meet its commitments to halt biodiversity loss.

Transdisciplinary Approach (max. 1’000 characters)

The project brings together scientists, conservation authorities, ecological consultancies, restoration experts, and industry partners. Together, they co-produce knowledge through surveys, experiments, and workshops to identify suitable species and sites. Field trials and propagation work provide practical experience, while continuous exchange between science, practice, and policy ensures relevance. The resulting open-access toolbox will compile guidelines, case studies, and best practices for use long after the project ends. By building a community of practice, the project aims to make assisted migration a recognised tool in biodiversity conservation and restoration.
