Conservation of Biodiversity Through the Greening Business

Sumitomo Forestry Landscaping Co., Ltd. makes comprehensive proposals for the landscaping and greening of many different environments, from houses, parks and residential property development through to regeneration of the natural environment. Areas designated for planting are categorized into four areas according to their conservation level—protected areas, conservation areas, satoyama areas (countryside close to rural communities) and town areas and local seeds, seedlings and saplings, native plants, and cultivars are planted after considering their effect on ecosystems. In a conservation area such as a nature park, for example, only local seeds, seedlings or saplings are used. In the landscaping of residential gardens in town areas, consideration is also given to color in the space by planting not only native species, but also cultivars and certain introduced species (introduced since the Meiji era) which have no effect on the local ecosystem. The Group actively promotes use of these plants for landscaping and greening as Harmonic Plants® that are chosen based on biodiversity considerations. The Group also has in place a policy of not using species that clearly have an adverse impact on local ecosystems*1 and a division responsible for coordinating technology at Sumitomo Forestry Landscaping Co., Ltd. checks that such species are not used.

Efforts for the Entrenched Widespread Use of Harmonic Plants®

Sumitomo Forestry Landscaping Co., Ltd. has adopted a biodiverse approach to tree-planting for Sumitomo Forestry custom-built detached houses and subdivision homes. For instance, it used Harmonic Plants® in the exterior landscaping for all 710 subdivision homes completed during fiscal 2015. It also used Harmonic Plants® in landscaping at all 22 Sumitomo Forestry model homes that opened during fiscal 2014, in an effort not only for Harmonic Plants® to be incorporated into planting proposals for customers, but also to raise awareness among employees.
Furthermore, in October 2014, in conjunction with Sumitomo Forestry, the Company launched a new concept of complete garden proposals called “Sumitomo Forestry Gardens.” The proposals, which integrate home and garden design, include plans for planting that take biodiversity into account based on Harmonic Plants®.
Native species are one class of Harmonic Plants®. Targets for the number of native species planted have been established in the Mid-Term Environmental Management Plan, and in fiscal 2015, 36,050symbol for third party assurance native species were planted at Sumitomo Forestry’s custom-built detached houses and subdivision homes.

Park Renovation Project at Kyukamura Irago, Aichi Prefecture

Sumitomo Forestry Landscaping Co., Ltd. has been taking part in a seashore plants-themes renovation project with consideration for biodiversity at the holiday village, Irago Park, in Tahara City of Aichi Prefecture in collaboration with Eco-AssetTM Consortium member corporations since September 2013.
The neighboring beach plays an important role in the ecosystem network, including serving as a spawning ground for green sea turtles and as a migratory point for hawks such as the gray-faced buzzard and the honey buzzard.
The project involves developing the Irago Salala Park, Japan’s first garden for observing coastal flora. In October 2014, approximately 2.5 hectares of the total 5 hectares were opened for the sightseeing area which will be the main facility. In fiscal 2015, the constructions of Masonry Bridge leading to the observation deck and a Rare Species Protected Zone on the island in the middle of the pond have completed.
In promoting this project, various methods have been adopted for regenerating the vegetation, for instance attempting to restore the coastal vegetation that had originally been there by turning the soil over and reviving the buried seeds that had been dormant underground. The park is scheduled for completion in fiscal 2017.
