Biodiversity conservation in local regionsConservation Activities in the native habit of aldrovanda vesiculosa (Hanyu City, Saitama prefecture)

Hanyu City, Saitama Prefecture, is the home of Hanyu Sekisui and Hozoji-numa, where Aldrovanda vesiculosa, the sole extant species in the flowering plant genus Aldrovanda of the family Droseraceae grown in the wild. Aldrovanda vesiculosa is carnivorous, feeding on small insects. The Aldrovanda vesiculosa in the Hozoji-numa area of Hanyu City was declared a protected species in 1966, with the city and the Aldrovanda vesiculosa preservation society working together to maintain the area around the natural habitat and educate the local residents. After almost being washed away due to typhoon-induced flooding, Aldrovanda vesiculosa in the area recovered to about 150,000 plants as of September 2016.

Hanyu Sekisui continues to work to preserve local biodiversity and has launched cooperative efforts with local conservationists to preserve the natural habitat of Aldrovanda vesiculosa. Employees and family members on 18 March 2017 worked together to capture invasive alien insects so as to prevent damage to local Aldrovanda vesiculosa. The company also plans to cut back surrounding growth in July.

In cooperation with the local communities, Hanyu Sekisui looks forward to further efforts aimed at preserving the natural habitat of Aldrovanda vesiculosa.
