The Northeast China Plain deciduous forests cover the flat interior of the Northeast China Plain across the Manchuria region of China, extending into adjacent northwestern North Korea and following the Liao and Songhua rivers toward the Heilongjiang (Amur) River on the Russian frontier. The original vegetation is broadleaf deciduous forest, with oak, maple (Acer), elm (Ulmus), tilia (linden), and ash (Fraxinus) in the south, giving way to Mongolian oak and Daurian birch (Betula) and conifers toward the north. The climate is humid continental with hot summers (Koppen Dwa), marked by large seasonal temperature swings, cold winters, and warm, rainy summers. The fertile plains were converted to agriculture long ago, but China's largest reed marshes at the mouth of the Liao River on the Bay of Bohai still support important migratory bird populations, including the endangered red-crowned crane and the ecoregion's flagship, Saunders's gull. Gardeners in comparable cold-winter climates may recognize hardy ornamental and shade-tree genera native here, such as maple, linden, ash, elm, and birch.

About the temperate broadleaf & mixed forests biome

Four-season forests of deciduous hardwoods — oak, maple, beech — often mixed with conifers, shaped by warm summers and cold winters. Trees leaf out in spring and color in autumn; the generally fertile soils have made these forests heavily settled and farmed.

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.
