Environment:Environmental Topics Vol.1 Hamamatsu Business Office Maintenance of biotope

Fujitsu General Group set up a biotope (Note 1) in the premises in March 2013 and is operating it to contribute to a "natural symbiosis society" in recognition that "our business activities are receiving grace from and influencing to biodiversity".
Our biotope serves as a gene bank (Note 2) of rare fauna and flora while preserving animals and plants at rural Satoyama (Village) of Hamamatsu City and conserving the diversity of regional ecosystem.

State in October 2017

Tanakia lanceolate and Pronodularia japanensis (Shizuoka Prefecture RL2017 endangered IA (CR))

Tanakia lanceolate

Pronodularia japanensis.

The Tanakia lanceolate grows in a river and moves to a canal in the breeding season to lay eggs in Pronodularia japanensis. The Pronodularia japanensis parasitizes in the fins of killifish and loach at the larval stage, and then, grows as a juvenile spat at the river bottom. In recent years, as the number of Tanakia lanceolate is decreasing due to the decrease in the number of Pronodularia japanensis because of the change to the concrete of waterway and due to the river breaking off by a dam.

In this biotope, within Shizuoka Prefecture, Tanakia lanceolata and Pronodularia japanensis which inhabit in the Miyakoda River system near the site of Hamamatsu Business Office are preserved in the river and pond outside the habitat.

Note 1 biotope:
It means the place where diverse creatures live. In urban areas where development has advanced in recent years, there is almost no natural environment left where wildlife can settle down, so that the establishment of a biotope that provides living space for living creatures by connecting disconnected inhabitation and growth areas is sought.
Note 2 gene bank:
It is a facility for preserving rare fauna and flora.
