The Amur meadow steppe stretches across two sections of the middle Amur River valley, straddling the Russian Far East (Amur Oblast and Khabarovsk Krai) and northeastern China (Heilongjiang province). Because the land is a flat floodplain on alluvial soil with a high water table and frequent flooding, it has remained largely free of forest, instead supporting extensive wetlands of bogs and grasslands; wet meadows are dominated by reed grasses (Calamagrostis) alongside many members of the parsley family (Apiaceae) and Spiraea shrubs, with Mongolian oak and Daurian birch also present. The climate is humid continental of the cool-summer subtype (Koppen Dwb), with long, cold winters and short, cool summers. The region is a stronghold for threatened wildlife, including the red-crowned crane, Oriental stork, and Blakiston's eagle-owl, while the kaluga sturgeon serves as the ecoregion's flagship species. Much of it has been converted to cropland and only a small fraction is protected, within reserves such as Khingan and Bolshekhekhtsirsky.

About the flooded grasslands & savannas biome

Grasslands and savannas subject to seasonal or year-round flooding, including large wetland complexes. Exceptionally productive, they concentrate waterbirds and aquatic life.

Catalog plants suited to this ecoregion

Computed from each plant's stated USDA zone range against this ecoregion's CHELSA-derived current zone range, with the CHELSA mid-century warming delta applied for the projection. Plants whose stated range falls outside both the current and projected zone end up dropped; the rest land in one of the three buckets below.

Collections for this ecoregion

Curated multi-plant collections whose members all fit this ecoregion's zone range — no won't-grow members smuggled in. Overall fit class shown per collection is the weakest link across its members.
