Invasive Species in China

 

China is the world's third largest country and one of the richest in terms of biodiversity. Its vast territory stretches 5,200 km from east to west. It spans 50 degrees of latitude, and covers five climatic zones: cold-temperate, temperate, warm-temperate, subtropical, and tropical. A wide range of habitats and environmental conditions makes China especially vulnerable to the establishment of invasive species of foreign origin. Potential invasive alien species from most areas of the world may find suitable habitat somewhere in China.

Criteria to define an invasive alien species:

has been introduced into an area where it is not native from its natural range by either intentional or unintentional human activity;

has established a self-reproducing population in a local natural or artificial ecosystems; and

has caused obvious changes in a natural ecosystem or landscape, or has caused damages to a local natural or artificial ecosystem.

We also consider alien species in China to include species introduced outside their native ranges within China as well as non-native species introduced from other countries.
