Forest development through cooperative work with stakeholders

Aiming to contribute to the development of local communities, employees of the Ricoh Group have been working together with various parties, including local governments and local residents, on “forest development through cooperative work with stakeholders” since 2017. We work on activities to promote the restoration of satoyama, a rural landscape, with rich biodiversity and the revitalization of local communities.

Ena forest project

Ricoh and local residents’ collaborative efforts to conserve Ena forest for future generations 100 or more years into the future

— Contribution to global environmental conservation, raising the next generation, and community development — 

●Location:Japan, Gifu Prefecture
●Period:2014 ~ to present
●Activity : Aiming to create a local forest that can coexist with a rich natural environment in collaboration with local residents
The Ricoh Group has been engaged in activities to conserve a forest in Ena, a city in the southeast part of Gifu Prefecture. The forest is located on the premises of a plant operated by Ricoh Elemex Corporation, a manufacturing subsidiary of the Ricoh Group. Ricoh Elemex purchased the vast tract of land in 1963 to build its manufacturing plant. In addition to the site used for the manufacturing facilities, the acquired property includes a huge undeveloped area encompassing more than 40 hectares.The Ricoh Group started its forest conservation activities on this site in 2010 to mark the Tenth Meeting of the Conference of the Parties to the Convention on Biological Diversity (COP 10) held in Nagoya, Japan. The activities reflect our gratitude to the local community for its support of our manufacturing facility over the past almost 50 years as well as our commitment to maintaining harmonious relationships with our neighbors.

Biodiversity targets and evaluation of Ena Forest

Aiming for a forest where diverse organisms can live by maintaining an ecosystem in which the target species, the luehdorfia butterfly and the scarlet dwarf, also known as the pygmyfly (Luehdorfia japonica, Nannophya pygmaea), can live.

<Actual results>
Since 2010, the habitat of the target species has been confirmed.

A vegetation survey conducted in cooperation with the C.W. Nicol Afan Woodland Trust in the fall of 2010 revealed that the forest near the Ena Plant is home to a wide variety of hygrophyte plant species, including some that are endangered, and that it has developed a unique ecosystem thanks to the lack of human interference over a very long period. Ricoh Elemex employees interested in conservation and some like-minded local residents started forest conservation activities in 2011. Later, in April 2014, aiming to utilize the precious forest resources together with the local community, we launched the Ena Forest, Nakasendo Satoyama Conference, which consisted of representatives from among local residents, local businesses, and nonprofit organizations as well as representatives of Ricoh Group companies. The organization has since been leading the efforts by local volunteers and Ricoh Group employees to conserve the forest and its rare species by forest management activities such as tree thinning. Participants in each volunteer activity event are rewarded with a gift certificate that can be used in shops operated by the Ena Tanpopo Social Welfare Organization, including a bakery, a produce store, and a local specialty store. As the forest is open to the local community, children also visit the forest to take part in educational programs where they learn about and connect with nature, while adults can enjoy relaxing walks through the woods.
Through these activities, the Ricoh Group will continue to make positive contributions not only to environmental conservation but also to the development of the next generation and the invigoration and development of local communities.

Surveys and Evaluations to Understand the Ecosystem

We regularly conduct large-scale vegetation surveys at Ena Forest to assess and improve the conservation status.

<Survey Report 1>

In a vegetation survey conducted in September 2010, 289 species of plants belonging to 85 families were identified, and six endangered species were recognized. The forest is mainly composed of fuelwood for charcoal production, such as the joicham oak (quercus serrata and sawtooth oak (quercus acutissima), although precious species such as bladderworts (utricularia caerosa), start magnolia (magnolia stellata), and alder tree inhabit the wetlands and their water sources. As for insects, scarlet dwarfs were found in the wetlands, and Japanese luehdorfia were found at the forest edge in early spring.

<Survey Report 2>

In the 2016 vegetation survey, 337 species of 96 families (more than in 2010) were confirmed, and 10 endangered species were also identified. Compared to 2010, the vegetation and its diversity has been maintained and is considered to be in the same condition or better. The naturalization rate has increased from 6.2% for 18 species to 7.7% for 26 species, and naturalized plants that were found only at the forest edge in 2010 can now be seen near the entrances and exits of forests and along their forest trails. Although this is not a major problem at present, we are carrying out conservation activities to prevent the growth of alien species caused by bringing in seeds from the outside. As a result of conducting an insect survey focusing on the target species, the Japanese luehdorfia and the scarlet dwarf, 28 species of dragonflies, 23 species of butterflies, 15 species of beetles, and 11 other species were confirmed. Since we did not conduct an insect survey at the beginning of the activity, we cannot compare these figures, but the target species of Japanese luehdorfia and scarlet dwarf tended to increase. The results of the vegetation survey and insect survey conducted in 2016 will be reported in a debriefing session for the people who participated in the live forest-building activity (conservation activity), and the results of the activity will be revealed to everyone who participated. It was a good opportunity to share the knowledge we gained and learn that it is a forest with abundant vegetation. These surveys are conducted in collaboration with local animal and plant conservation groups.
