Wary!
These invasive alien species

Water hyacinth
Water hyacinth is native to South America in the early 20th century as an ornamental plant introduced to the mainland as pig feed and promoted as pig feed because its large reproduction often covers the entire river and lake surface, resulting in a large number of aquatic organisms due to lack of oxygen and insufficient sunlight and death and damage to the ecological balance in the water
"A Yellow Flower in Canada"
"Canadian Yellow Flower" is an ornamental plant introduced from North America in Shanghai and other places in the mainland in the 1930s with strong reproductive and rapid space-occupying ability to suppress the growth of native plants and destroy the ecological balance of vegetation in the invasion area
Brazilian tortoise
The Brazilian tortoise, also known as the red-eared turtle, is recognized worldwide as an ecological killer
China and other countries
It has been classified as a dangerous invasive alien species
Red fire ants
Red fire ants are quarantine pests in mainland agriculture, forestry and imported plants and are also recognized as one of the 100 most dangerous invasive species in the world, such as red fire ants can directly eat the seeds, fruits, and young shoots of crops, resulting in crop yield reductions and affecting the growth and reproduction of some animals
Fushou snail
Fushou snail, also known as large bottle snail and apple snail, is native to the Amazon River Basin of South America in the early 1980s as a edible snail introduced to China as a food snail because of its strong adaptability, breeding quickly became a huge harmful invasive alien species

Coconut heart leaf nails
Coconut palm beetle is a highly dangerous alien pest native to Indonesia and Papua New Guinea and is now widely distributed in the Pacific Islands and Southeast Asia, with fast reproduction, destructive and difficult to control
In response to the problem of invasive alien species, the mainland's management system is constantly improving. The Measures for the Administration of Invasive Alien Species came into force on 1 August 2022, and the Measures clarify that the Ministry of Agriculture and Rural Affairs, together with relevant departments, shall establish a census system for invasive alien species, organize a national census every ten years, establish a monitoring system for invasive alien species, build a national monitoring network for invasive alien species, and establish an information release system for invasive alien species. The solution to this problem also depends on the efforts of society and individuals. Prevent invasion of alien species. Everyone is responsible!
