The Suiphun-Khanka meadows and forest meadows ecoregion centers on Lake Khanka, straddling the border between Heilongjiang Province in China and Primorsky Krai in the Russian Far East, extending along the Ussuri and Suifen (Razdolnaya) river valleys. Largely unforested, flat, and marshy, it is a mosaic of wet meadows, grassy bogs, and reed beds, with Manchurian water-rice, reed grass, and sedges near the water and drier prairie-like grasslands beyond; gallery forests carry Mongolian oak and Dahurian birch alongside Manchurian and Siberian apricots, almond cherry, and Chinese hawthorn. The climate is humid continental with cool summers (Koppen Dwb), bringing long, cold winters and short, mild summers. A probable refuge during the late Pleistocene glaciation, the region supports more than 700 terrestrial plant species and is a vital migratory-bird stopover, hosting the red-crowned crane as its flagship species along with Oriental storks; protected areas include Russia's Khanka Nature Reserve and China's Xingkai Lake National Nature Reserve. Among its native flora are ornamental kin familiar to gardeners, including Komarov's lotus and English iris.
