The United Nations Decade for Ecosystem Restoration begins in 2021. The question is how to promote ecosystem restoration and establish the optimal methodology.

Ecosystems that have been severely damaged by disasters, etc., and the ecosystems that are created in an effort to repair them, are new habitats that are different from previous ecologists, and are places where new natural selection is at work. Therefore, it is predicted that incorporating explicit consideration of match/mismatch and rapid evolution of adaptive traits, which have so far been insufficiently neglected, will have a bearing on the success or failure and optimization of ecosystem restoration.

We aim to verify this prediction through large-scale experiments using the world-class research forest of Hokkaido University and propose a method.
