North-Eastern Asia

The Region of the study defined in this project is named as the "North Eastern Asia". It lies in three countries: China, Russia and Japan. It includes five Russia provinces (oblasts): Primorsky Province, Khabarovsky Province, Amur Province, Sakhalin Province and Evreiskaya Autonomous Province. The region area in China covers more than 0.9 million km2 in part of four provinces: Heilongjiang, Jilin, Inner Mogolia and Liaoning. The first two are the only Chinese provinces which lie (almost) completely within our study region. The Japanese Hokkaido prefecture lies also within the boundaries of the region of study.

The forests in Siberia make up 20% of the planet's forests and 60% of the boreal forests of the Northern Hemisphere. The large tract found in the north of the study area is just a small portion of the boreal forests of Siberia as a whole.

North-Eastern AsiaThe terrain of the region is largely mountainous. The cold temperatures that create permafrost and seasonal droughts favour coniferous forests of larch, spruce, fir, and pine. This is the world's largest remaining wilderness and a place that provides a secure home for many species of plants and animals.
East Siberian Taiga and Trans-Baikal Coniferous Forest eco-regions, each in its own way, present extreme climatic conditions, while two additional forest eco-regions in the boreal zone (Da Xing'an/Great Hingan-Dzhagdy Mountains and Okhotsk-Manchurian Taiga) differ from the East Siberian taiga mainly because they experience greater influence of the "Manchurian/Daurian" biota to the south and are located in a somewhat warmer climate zone.

The degree of human impact on the environment in this region is uneven, but already quite substantial in all countries. Plains support extensive agriculture, especially in China, while other dominant land-use types are mining exploitations and forestry. Development of international trade spurs construction of transportation infrastructure, oil and gas pipelines. Several major tributaries are already blocked by hydropower dams, while lower reaches are severely affected by water pollution from industry and agriculture. Good land-management practices are needed to cope with accelerating climate change, widespread wildfires and land degradation.
