Biodiversity Measures

Based on the “Gohon no ki” (Five Trees) Planning, which is promoted by Sekisui House as the sponsor of SHR, we conduct maintenance and management of planting and other greenery measures, basically by selecting tree species in consideration of ecosystems.

Gohon no ki” (Five Trees) Planning Promoted by Sekisui House

“Gohon no ki” (Five Trees) Planning is a Sekisui House original proposal for the creation of gardens and communities. In this planning, “Five Trees” indicates that Japanese indigenous trees will be promoted as “Select five native species, three trees for birds and two trees for butterflies.” We aim to co-exist with the surrounding nature and create a garden for which admiration will grow as time passes by planting indigenous trees that have close ties to the lives of living things and are in harmony with Japan’s climate.
