Oze and the Ramsar Convention
In November 2005, Oze was registered as a Ramsar Convention site, in recognition of its importance as a wetland habitat for migratory birds. The convention, named after the Iranian city where it was signed in 1971, is an international treaty for the conservation and sustainable use of wetlands, and covers rivers, lakes, paddies, reservoirs, sea coves, tidal flats, and mangrove forests. As of December 2019, there are 52 Ramsar sites in Japan and over 2,000 in the 170 countries that signed the agreement.
