Site details
Site description: Lake Koetoi-Onuma is located in the east of Wakkanai City, has a perimeter of 12 km around, and a maximum depth of 2.2 m. In 1958, the lake was connected with the sea by a flood prevention project that straightened the Koetoigawa river. There is abundant wildlife in the fresh water lake and the brackish water. Many birds breed here, and Tundra Swans and ducks stop over in spring and autumn migrating seasons.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
