Editing Changbai Mountains (section)

==Flora and fauna==
The vegetation of the mountain slopes is divided into several different zones.  At the top, above {{convert|2000|m|ft|0|sp=us}}, [[tundra]] predominates.  From {{convert|1700-2000|m|ft|0|sp=us}}, vegetation is dominated by mountain birch and [[larch]].  Below this zone, and down to {{convert|1100|m|ft|0|sp=us}}, the dominant trees are [[spruce]], [[fir]], and [[Korean pine|pine]].  From {{convert|600-1100|m|ft|0|sp=us}}, the landscape is dominated by mixed forest consisting of [[Amur linden]] (''Tilia amurensis''), pine, [[maple]], and [[elm]].  Further down, a [[temperate hardwood forest]] is found, dominated by second-growth [[Populus|poplar]] and [[birch]].<ref>Liu, Q.J., Takamura, T., Takeuchi, N., Shao, G. (2002).

There are five known species of plants in the lake on the peak, and some 168 have been counted along its shores. The forest on the Chinese side is ancient and almost unaltered by humans. [[Birch]] predominates near the [[tree line]], and [[pine]] lower down, mixed with other species. There has been extensive [[deforestation]] on the lower slopes on the North Korean side of the mountain.{{citation needed|date=August 2018}}

The area is a known habitat for [[Siberian tiger]]s, [[bear]]s, [[Wolf|wolves]], and [[wild boar]]s.<ref>Gomà Pinilla, D. (2004). Border Disputes between China and North Korea. China Perspectives 2004(52): 1−9.</ref> The [[Ussuri dhole]]s may have been extirpated from the area. Deer in the mountain forests, which cover the mountain up to about {{convert|2000|m|sp=us}}, are of the Paekdusan [[Siberian roe deer|roe deer]] kind. Many wild birds such as [[black grouse]], [[owl]]s, and [[woodpecker]] are known to inhabit the area. The mountain has been identified by [[BirdLife International]] as an [[Important Bird Area]] (IBA) because it supports a population of [[scaly-sided merganser]]s.<ref name="bli">{{cite web|year=2013|title=Mount Paekdu|url=http://datazone.birdlife.org/site/factsheet/16080|access-date=2013-05-12|work=Important Bird Areas factsheet|publisher=BirdLife International}}</ref>
