In order to ensure ex-situ conservation, it is necessary to pay
attention to the range of travel of plants and animals. For example,
it is not desirable to protect Hokkaido’s endangered
species at a factory in Kyushu, which has a different climate and
living environment. How far, then, can endangered species be
transferred?
One guideline is to keep them within a river basin. “Basin”
refers to the area of land where rivers catch the rain that falls
and can be considered to be a single unit of an ecosystem.
Therefore, Toshiba Group has a principle of moving plants
and animals within the same basin when its business and
production sites do so for the purpose of ex-situ conservation.
In Japan, 109 first-class rivers and their valleys occupy about
70% of the country’s land, and Toshiba Group has confirmed
which valley each of its domestic businesses and production
sites are located in. Also at its business and production sites
outside Japan, the Group promotes ex-situ conservation as
necessary while referring to maps of basins and vegetation
distribution charts for each region, marshland characteristics,
and other data as well as paying attention to ecosystem
units.
