Great Purple Emperor Butterfly Forest Creation Project to link people, nature, and communities

Activity grant

Project Description

While some successes have been achieved in the restoration of protected forests through volunteers, who rescue great purple emperor butterflies in response to a sense of crisis towards the loss of woodland environments from the development of the Tsukuba Express Railway, a vision has yet to be established for the preservation of large-scale green areas even after development. In this project, we will study the past and present of this woodland environment including green areas, and start activities for sharing a future image of the woodlands with people in local communities. We will work to continually conserve woodlands with great purple emperor butterflies serving as a benchmark for the charm of living together with abundant nature.
