Suiphun–Khanka meadows and forest meadows
Ecoregion (WWF)
The Suiphun–Khanka meadows and forest meadows ecoregion (WWF ID: PA0907) (also: Ussuri-Wusuli meadow and forest meadow) is a relatively small ecoregion centered on Lake Khanka, a fresh water lake in the Russian Far East, with a portion in China. The terrain is unforested, flat, and marshy. The area is an important stopover spot for migratory birds, including many vulnerable species. It has an area of 33,929 square kilometres (13,100 mi2), and is in the Flooded grasslands and savannas biome.
Location and description
The headwaters of the Ussuri River cross the northern edge of the ecoregion, Lake Khanka dominates the middle, and the Suifen River (Razdolnaya River in Russian) feeds the lake from the south. The lake straddles the border between Heilongjiang Province in China to the west, and Primorsky Krai in Russia to the east. The only outflow from Lake Khanka is the Songacha River, a tributary of the Ussuri, and eventually the Amur River. The entire area is known as the Khanka Depression, as it is a lowland surrounded by mountains and higher ground. The ecoregion is surrounded by the Manchurian mixed forests on the north, west, and south, and the Ussuri broadleaf and mixed forests on the east.
Climate
The region has a Humid continental climate - cool summer subtype (Koppen classification Dwb).

Why this record matters
The phrase “ecoregion (WWF)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Oct 27, 2025. The linked authority identifier is Q58268812. Authority coordinates are 45.250, 132.750. None of the 1 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
