Ecoregion PA505, Da
Hinggan-Dzhagdy Mountains conifer forests, are found in Amur, Heilongjiang,
Inner Mongolia,and Zabaykalsky. A unique flora (Daurian) of larch, oak, hazel,
alder, birch, poplar, and elm is found in this mountain area. The forests were
mostly uncut until the 20th century and constitute the largest
single timber stand in the world. The mountains are the southern limit of
wolverines, lynx, and elk. The Greater
Hinggan Mountains divide the Manchurian plain from the Mongolian plateau. The
area is the site of one of the largest wildfires in recent history, known as
the Black Dragon fire. It took place in 1987. It was started by a temporary
employee operating a brush cutter, which caught fire and spread to grasslands
and nearby woods on May 6, 1987. Other fires started burning about the same
time in Russia and China. The fire eventually burned millions of acres in China
and Russia (Pyne, 1989; Salisbury, 1989).
