The area of forests affected by pests, animals or diseases in
the first half of this year reached more than 8.4 million hectares,
a 9 percent increase compared with the same period last year,
according to statistics from the State Forestry Administration.
The administration said the overall situation remained stable in
the first half of the year and there was a decline in the number of
pests or diseases affecting large-scale forests.
However, the situation has become more acute in some regions, it
said.
Among the affected areas, over 7 million hectares saw the damage
brought by pests, nearly a 7 percent rise compared with the same
period last year, while 423,000 hectares were hit by diseases, down
26.6 percent.
In addition, more than 980,000 hectares of forests were affected
by rats or rabbits, up 66.5 percent, the statistics said.
Problems brought by invasive alien species have become more and
more noticeable as several alien grass species have spread
rampantly in areas like southwest China's Yunnan
Province and south China's Guangdong
Province, affecting 10 million hectares of forest.
The administration predicted that the area of forests affected
by pests or diseases in northeast and north China will increase
slightly, while the impact of rats or rabbits in forests in
northwest China will become more serious.
The administration has ordered all levels of forestry
departments to take effective measures to prevent and fight against
pests or diseases in forests.
One of these efforts took place in a 660-hectare forest located
in the Great Hinggan Mountains, which is one of the nation's
important forestry base. The forest was damaged seriously by pests
due to dry weather.
After three months, more than 3,000 kilograms of pests were
killed in the forest by the end of August and the situation has
been brought under control, according to the People's
Liberation Army Daily newspaper.
