Dragonfly migration to green space in industrial zone

Dragonfly migration to green space in industrial zone

The Mazda R&D Center Yokohama (MRY), Mazda's base for research and development in Yokohama, has supported the Keihin Afforestation Project promoted by Yokohama City. Since 2004, the center has also supported "How Far Does a Dragonfly Fly?" Forum, a collaborative project implemented by companies, universities, local governments, and citizens to investigate and track the flight of dragonflies. Through such projects, they are working to revitalize nature and expand green environments.
In 2009, MRY transplanted indigenous water plants to create a biotope based in a pond on its premises. Now there are many unusual creatures living in the water, and rare dragonflies including polycanthagyna melanictera visit the biotope. This project has received high praise from experts, who have said that the development of green spaces in the Keihin Industrial Zone has allowed these rare dragonflies to return.
Investigations of the flight of dragonflies are carried out every summer when the dragonfly population is stable, in 10 locations in coastal industrial areas.

In FY2020, MRY cooperated in conducting a survey for three days from August 3, during which field researchers observed and caught dragonflies to trace their species, flight patterns and travel between survey points. (The dragonflies were released after the survey.)
