To restore the altered on appropriate forest development and environment to its original state, biotopes have been created within interchanges. These biotopes are created by conservation, as part of its eff orts to create a using forest topsoil generated during construction work and by replanting rootstocks of felled trees. recycling-oriented society. With the passage of the years, a variety of indigenous fauna and fl ora have settled in the region, facilitating the restoration of the natural environment to its original state.

River Project Nature Restoration What is the Meiji River COLUMN Improvement Project Creation of diverse waterfront In 1887, a project for improvement of the Kiso River environments with Kereppu spur dikes downstream area was launched under the guidance of Johannes de Rijke, a Dutch engineer, to An institute that conducts research to realize The Kereppu spur dikes, made of brushwood, soil and stones, were constructed appropriately separate the Kiso-Sansen（lit. the Kiso harmonious coexistence between people and during the Meiji River Improvement Project（1887‒1912）. The purposes of the Three Rivers, i.e., the Kiso River, Nagara River and the natural environments of rivers and lakes construction were to prevent riverbed scouring by moderating water flows so Ibi River）, which used to fl ow in a meshed pattern around estuaries, into three rivers, as they are in ＊ Purpose as to promote deposition of sediments, and thereby ensure the safety of levee The Aqua Restoration revetments, and maintain the width and depth of low-flow channels.（The Kiso their present form.

Using these streams and ponds, the ARRC conducts research into the interaction between organisms and river environments. The shapes of experimental streams can be changed, and the flow rates can be also controlled to simulate artifi cial fl oods. ＊ Open for the public to visit and tour the ARRC The ARRC has opened its experimental streams for the public to tour and visit. By making advance reservations, visitors can participate in a one-to-two-hour tour guided by dedicated staff members, who outline the research done by ARRC and give explanation of the experimental streams. ＊ Environmental education programs As a public research facility, the ARRC also provides environmental education programs to give participants a better understanding of the river environment.
