Conservation of Biodiversity Through Business

Harmonic Plants® for the Conservation of Biodiversity
Through the Greening Business

Sumitomo Forestry Landscaping Co., Ltd. is selecting greening plants based on the garden vegetation plans according to factors such as the impact on the ecosystem and genetic system to protect the biodiversity in Japan. These greening plants that are biodirvisty friendly have been named Harmonic Plants® and are used throughout the entire greening business.

There are plants that have grown in Japan since long ago (native plants), plants that have come to Japan from abroad (migration plants) and garden plants (agrotype) for trees. Among these migration plants, there are species that will overrun areas where native plants live due to their characteristics, which endanger the biodiversity of the region (invasive plants*)

Garden vegetation plans are separated into four areas that take into account the conservation level (protected areas, conservation areas, satoyama areas, urban areas) to select plant species based on these areas. For example, in urban areas when building gardens for residences, the colorfulness is represented by selecting a balance of greening plants from non-invasive migration plants around a main selection of native plants, including agrotype plants. In addition, the Group has in place a policy of not using invasive plants that clearly have an adverse impact on local ecosystems 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 has adopted garden vegetation that is friendly to biodiversity in Sumitomo Forestry custom-built detached houses and condominiums. 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®.

In fiscal 2016, all of the garden work in housing exteriors of the 832 condominiums that were completed utilized garden vegetation via Harmonic Plants®. It also used Harmonic Plants® in landscaping at all 17 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.

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 2016, 30,614 native speciessymbol for Independent assurance were planted at Sumitomo Forestry’s custom-built detached houses and subdivision homes.

Biodiversity Consulting Business

Social and Environmental Green Evaluation System Certification Support

Knowledge in expert fields around green assets such as urban greening and biological survey risk management are required to respond to the broad needs of green zones in demand in an environmental era. Sumitomo Forestry Landscaping together with Sumitomo Forestry, InterRisk Research Institute & Consulting, Inc., and Regional Environmental Planning, Inc. have worked to popularize social contribution green zones that use company-owned green environments via consultant services with the organization of a consultant team called the Eco-Asset™ Consortium.

The Forest of Toyota, which the Eco-Asset™ Consortium consulted on about the green conservation plan, was highly praised and received the 3rd Green Society Award in October 2015. The Green Society Award is held by the Organization for Landscape and Urban Green Infrastructure to evaluate greening from green land open to the general public to biodiversity conservation activities and it is the premiere award that praises social contribution through greening.

Meidensha Corporation Office Biodiversity Project

Sumitomo Forestry Landscaping with the cooperation of the companies participating in the Eco-Asset™ Consortium is supporting biodiversity efforts that utilize existing green areas at the Meidensha Corporation Numazu site. This Numazu site of the Meidensha is the core production site of the Meidensha Group, which began business in 1961 surrounded by the rich natural environment of Numazu from Mt. Fuji and Suruga Bay to the natural springs of Kakitagawa River. The land holds a wide range of potential in a diverse ecosystem with a natural impact on both the nature of hilly areas running to Mt. Fuji to the north and the seaside of Suruga Bay to the south.

The Eco-Asset™ Consortium propose programs to interact with nature that use existing green lands. In fiscal 2016, we held biodiversity activities twice with the participation of our employees.
