In March 2009, we built Hanei no Hiroba (Square of Affluence), an area of about 11,000 m2 of greenery in Eco Solutions Company in the Kadoma site, and a corner of the greenery was made into a biotope of 300 m2. To make the best of its location positioned between the Yodogawa River and Tsurumi Ryokuchi Park in Osaka Prefecture, we have been monitoring its living organisms following expert advice and instructions of Osaka Prefecture University from the stage of planning for the biotope. The biotope has been maintained by volunteering employees from its start. Each early spring, spot-billed ducks nest and hatch their eggs in the biotope, and the ducklings help raise the environmental awareness among employees.
In June 2012, with the proposal and instructions from the Aquatic Life Conservation Research Center of the Research Institute of Environment, Agriculture and Fisheries, Osaka Prefecture, we introduced hemigrammocypris rasborella (a fresh water fish belonging to the carp family) and monochoria korsakowii (a marsh plant) in the biotope. The number of hemigrammocypris rasborella that had been 40 at the start grew to roughly 1,500 in September 2013 and 7,400 in September 2014. Monochoria korsakowii are also growing steadily in number. In November 2013, with the conclusion of the Osaka Partnership Agreement among Osaka Prefecture, Osaka Prefecture University, Research Institute of Environment, Agriculture and Fisheries, and Panasonic, 100 Japanese Medaka fish (oryzias latipes; Ministry of the Environment & Osaka Prefectural Government endangered species) from Kita-Kawachi were newly introduced to the biotopes. The Japanese Medaka fish have also been confirmed to be growing steadily in number.
In October 2015, we invited local elementary school children to a workshop to study ecology and creatures in the biotope. We offered an opportunity for children to think about nature and the environment through learning about our biotope habitants and their lifecycles, as well as facts on endangered species.
In October 2016, the series of ecological activities by Eco Solutions Company was presented with the Osaka Environment Award 2015, hosted by the Osaka prefectural government. This award is given to an individual, non-profit organization, or company that has made significant contribution of a model activity in building an enriched environment. The company's joint environmental project with Osaka Prefecture University and the Research Institute of Environment, Agriculture and Fisheries, Osaka Prefecture, also received the Collaboration Prize under the Osaka Environment Award 2015.
The biotope is expected to contribute to the local biodiversity and greater awareness among employees.
