Initiatives that Deal with Biodiversity
Independent Practitioner's Assurance
Komatsu will maintain our commitment to protecting biodiversity in our business activities, recognizing the impact of those activities on the ecosystem.
Initiatives that Deal with Biodiversity
With the establishment of Komatsu's "Declaration of Biodiversity" and "Biodiversity Guideline" in January 2011, Komatsu business units worldwide began activities designed to preserve biodiversity.
Komatsu promotes initiatives to preserve biodiversity on two levels.
First, the Company continues to promote ongoing efforts to reduce the environmental impact of Komatsu's business activities. Komatsu also considers biodiversity when deciding how land is to be used, such as when building factories.
Second, Komatsu is becoming directly involved in the preservation of biodiversity, and at the same time expanding our "one-site, one-theme activities" to raise employee's awareness of the need to preserve local ecosystems.

Initiatives of Each Business Facility (Example of One Location One Theme Activity)
Komatsu Castex Ltd. (KCX)
Ex-situ conservation of rare specifies underway in an in-plant biotope-observing plant with guidance from local experts
With the cooperation of local experts, taking action to conserve rare species outside of their habitat range in biotope lake located on the plant premises Komatsu Castex Ltd. (located in Himi City, Toyama: hereinafter KCX), the only company in Japan producing parts for construction equipment and mining equipment by casting, has gained the support and guidance of the curators and biotope managers of the Toyama University Faculty of Science and Himi City's cooperative research center "Himirabo Aquarium" to create a biotope using the lake located in the "Furusato no Mori" (Hometown Woods) within the plant site of KCX main office. Since 2014, KCX has been working on conserving the rare species of "Minami Akahiritabira" (Acheilognathus tabira jordani) outside of their habitat range.
Minami Akahiretabira is a species of fresh water fish indigenous to Japan classified as cypririod acheilognathina acheilognathus and lives also in Shimane prefecture and Tottori prefecture of the Sanin Area as well as in Fukui prefecture and Ishikawa prefecture. Toyama prefecture is at the north limit of its habitat in Japan. In 2015 it was classified as an endangered species by the Toyama Prefecture Endangered Species Protection Measure as being threatened with extinction.
The Minami Akahiretabira is approximately 6cm long, and during spawning season (April - July), the male shows a distinct nuptial coloration while the female has the characteristic of growing a oviposting tube to bear eggs inside freshwater clams. Since freshwater clam is indispensable in ‘outside habitat range' conservation, when a total of 100 Minami Akahirekatabira were released in December 2014 and April 2015, about the same number of freshwater clams (mussels) were released into the same lake. Furthermore, since mussels become parasitic on the fins of freshwater fish when breeding, Tamoroko (Gnathopogon elongates) and Motsugo (Pseudorasbora parva) were also released for the breeding purpose of the mussels.
In addition, since the runoff water from the biotope ends up flowing into the Busshouji River water system that is downstream, only species that were captured from the Busshouji River water system were released in order not to affect the original ecosystem.
In August 2016, a year and a half since the release, a survey was done to see how much the population of the Minami Akahiretabira had increased. Results from the first and second surveys made it clear that there was an increase of over 1,000 fish (approximately 10 times the number released). Also, the survey results showed that the ratio of fish captured at the time of the census was over 80% Minami Akahiretabira, which means that Minami Akahiretabira is the dominant species within the lake of "Furusato no Mori".
We hope to continue working on this conservation project with the guidance of the local curators and biotope managers.
