In line with its declaration to preserve biodiversity in the Environmental Vision 2020, Daifuku has conducted surveys of the ecosystem within Shiga Works since 2012. The surveys have shown that many native species live within the Works, including some threatened species. We will establish more specific conservation plans and strive to create a Works that coexists harmoniously with nature.

Relationship between Daifuku and Biodiversity

Daifuku has mapped the relationship between product processes, land use, and other business activities and biodiversity. Based on this map, Daifuku notes the impact on ecosystems by the land use at Shiga Works, which is endowed with nature, and is conducting business activities that take biodiversity into account.

Conservation Activities at Shiga Works

According to a survey of ecosystems within Shiga Works conducted in fiscal 2012, we confirmed 642 native species on the grounds, including 49 threatened species. We will establish more specific conservation plans and strive to create a Works that coexists harmoniously with nature.

Yui no Mori

As part of a biodiversity preservation activity called Yui Project*, which started at Shiga Works in 2014, we set up the Yui no Mori (Mori = forest; comprised of a conservation pond, learning square, etc.). We engage in biodiversity conservation activities for a region-specific red pine forest, the rare clouded salamanders and other species in Yui no Mori. Furthermore, the forest is used as a learning environment inside and outside the company.

  • *Yui Project: Yui means to "bring together," and the project refers to various activities to bring together "water with greenery, people with nature, and people to people."

Symposium on biodiversity

In May 2014, we held a symposium to kick off biodiversity conservation activities at the Shiga Works, with 80 employees in attendance. At the forum, attendees heard a report on biodiversity surveys done within the Shiga Works through the four seasons. A panel discussion was also conducted with outside experts to discuss our approach to the activities in the future. In addition, we held a second symposium in July 2015 under the theme "Creating an energetic atmosphere for creatures and people with the Yui Project."

Nature Observation Event

We hold nature observation events, involving experts, so that employees have opportunities to interact with animals and plants living in Shiga Works.

Environmental Preservation Initiatives

Environmental Preservation Initiatives

To preserve the biodiversity of Yui no Mori, our employees created a floating island in a pond. We improved the waterfront environment for the benefit of birds, dragonflies, and other creatures. In addition, we adhered to our plans to promote the preservation of native plants, including any identified rare species.
