Relationship between Daifuku and Biodiversity

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

Conservation Activities at Shiga Works

In terms of site area, the Shiga Works is one of the largest land users in Shiga Prefecture. A survey of ecosystems within the Shiga Works confirmed 699 native species, and 52 rare and endangered species. In order to preserve this precious natural environment for subsequent generations, we have established a biodiversity preservation activity called the “Yui Project” to promote communication both within and outside the company, and we are pursuing various conservation initiatives.

Yui no Mori

As part of a biodiversity preservation activity called the 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 engaged in biodiversity conservation activities for a region-specific red pine forest, the rare clouded salamanders and other species. The project also serves 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."

Creating opportunities for interacting with nature

Creating opportunities for interacting with nature

We hold nature observation events and workshops involving experts, so that employees have opportunities to interact with plants and animals living around the Shiga Works. In fiscal 2018, these included making small ornaments from moss and Christmas wreaths using natural materials found on site, and holding of nature observation events that involved families of employees.

Planning exhibit (Lake Biwa Museum)

The eight neighboring companies* of the Shiga Works launched the “Lake Biwa Biodiversity Network” in 2016 to conserve the biodiversity of Shiga Prefecture, with a specific focus on the dragonfly. Through the “100 Dragonflies Initiative,” the goal is to search for, protect and educate the public about the 100 species of dragonflies found in Shiga Prefecture. Well commended, the initiative won the Shiga Biodiversity Grand Prize in 2017, and the Biodiversity Action Award in 2018 from the Japan Committee for the United Nations Decade on Biodiversity.
