The ecoregion is in the Palearctic ecozone, with a Humid Continental climate. It covers {{convert|187357|km2|sqmi|abbr=on}}.[1] Location and descriptionThe ecoregion covers a "Z" shaped area in which the northern section is a 400 km band of forest north of Khabarovsk parallel to the Amur River (which is 20-30 km to the south), the vertical band of which parallels the Ussuri River (which is 20-30 km to the west) on the western slopes of the Sikhote-Alin Mountains, and the base of which is the eastern slope of the Sikhote-Alin in Primorsky Krai.[1][2] ClimateThe region has a Humid continental, cool summer climate (Koppen classification (Dwb)). This climate is characterized by high variation in temperature, both daily and seasonally; with dry winters and cool summers.[3] {{climate chart| Climate at 46.75 N, 135.25 E |-10.7|6.4|.5 |-4.8|14|.5 |10|28.2|.9 |28.4|46.6|1.6 |39.7|59.2|2.7 |49.5|67.5|3.5 |57.6|73.9|5.1 |58|74.3|5.3 |47.1|65.7|3.8 |32.2|51.2|2.1 |11.9|28.9|1.2 |-5.36|11|.7 |float = right |clear = right |units = imperial |source = GlobalSpecies.org[4] }} Flora and faunaThe Ussuri forests are the most biologically diverse in northern Asia.[2] The maritime influence moderates the climate, precipitation is high enough to support rich forests, and the region is a boundary area between mountains, river flat lands, and sea coast.[5][6] The forests of the region are dominated by Spruce (Picea ajanensis), Dahurian larch (Larix gmelinii), Korean pine (Pinus koraiensis), Mongolian oak (Quercus mongolica), and Japanese white birch (Betula platyphylla).[6] ProtectionsNotable protected areas of the Russian Federation in the ecoregion include:
These are all IUCN class Ia "strict ecological reserves" (Zapovedniks). See also
