The Ussuri broadleaf and mixed forests lie in the Russian Far East, spanning Primorsky Krai and Khabarovsk Krai across the hills and slopes of the Sikhote-Alin Mountains north of the Amur River and east of the Ussuri River toward the Sea of Japan coast. These temperate mixed forests are notably rich, built from co-dominant trees including Korean pine, Mongolian oak, Manchurian and Korean ash, Japanese elm, Amur lime and Manchurian linden, Manchurian walnut, birches, larches, spruces and firs, and the distinctive Amur cork tree. The climate is humid continental with cool summers and dry winters (Koppen Dwb), marked by sharp daily and seasonal temperature swings. Often called the most biologically diverse forests in northern Asia, the region shelters Amur (Siberian) tigers, Manchurian wapiti and long-tailed goral, and endangered birds such as red-crowned cranes, oriental storks, and scaly-sided mergansers, with over 100 endemic plant species recorded. Gardeners may recognize several natives here, including the ornamental Amur cork tree and Korean pine.

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
