In April 2021, the Okinawa Environmental Research Support Section (OERSS) was renamed the Environmental Science Section. The section itself was established in 2019 as an independent function of the OKEON Chiramori Project with the goal of maintaining and promoting OIST's Okinawa terrestrial field research and community network in a more sustainable and stable manner.

Our goal is to carry out environmental research and education to ultimately contribute to the sustainable development of Okinawa by leveraging the local relationships, environmental monitoring networks, and experienced support teams developed by the OKEON Churamori Project.

  • Entomology Training at the University of the Ryukyus (September 2020)

    The entomology training we lead for undergraduates at the University of the Ryukyus has become an annual event. This year, although the situation was doubtful due to the pandemic, we were able to shorten it and conduct the training anyway. We were thus able to educate the students by having them observe the monitoring equipment and handle actual insect specimens, which would have been difficult to convey online. Although our time together was short, we are glad we were able to conduct the training in-person.

  • Beginning control of the browsing ant (August 2020)

    The alien species Lepisiota frauenfeldi, commonly known as the “browsing ant”, was confirmed to be established in Naha City, and a call by OIST’s Okinawa Environmental Research Support Section led to a cross-organizational collaboration between the City, Sumika Environmental Corporation, and the University of the Ryukyus that has begun control measures. Since around 2017, when fire ants were discovered in mainland Japan, several organizations including research institutes and government agencies have been working together to monitor for alien ants in Okinawa Prefecture.

  • Participation in the Okinawa Municipal Museum Council (July 2020)

    The Okinawa Municipal Museum Council met on July 13, 2020, and this year Section Leader Yoshimura was appointed as a member of the council. The Okinawa Municipal Museum is a community-based institution with a full staff of specialized curators, and has been a great help to us since the start of the OKEON Churamori Project. As a member of the council, Yoshimura will do his best to return the favor.
