It is much easier now than ever before for non-native species to penetrate and invade the home of other species. Thanks to important improvements in how humans travel across the world, animals, and plants can hitch a ride on boats, migrate via imported woods, and even come in our suitcases when we bring them home after exotic vacations in tropical countries. This seems to be harmless, but it actually has many negative effects on the environment and local ecosystem. So, beyond the issue of how to get rid of Japanese knotweed, which are the other most disastrous invasive species that cause serious trouble to homes in the UK? Let’s check it out.
Asian carps are brought from China and Eastern Russia to Europe and North America as a food and a part of the sports fishing or pet trade. They are large, reproduce quickly and have a big appetite, thus taking habitat and food away from native fishes. Indeed, this species has been known to eat the eggs of other species, while stirring up organisms and sediments from the river and lake beds and changing the whole environment. For these reasons, Asian carps are definitely one of the most disastrous invasive species in the world.
Originated in Azov seas and Caspian area, Zebra mussels are brought in ballast water to North America, Europe, and Russia. They are one of the most aggressive and disastrous invasive species as their population grows so quickly. A large number of zebra mussels in the water might have a severe impact on native plankton, which helps to reduce fish or food. Thus, these plankton-eating fishes have to look for a new food source or move to another place to survive. Unluckily, this is not an option for other species.
Farmers from countries with warm climates such as Australia bring cane toads from Central and South America to control pests in the crop. However, they generate toxic ooze as a defense mechanism that is harmful to many native species. With keeping their population in check, cane toads might explode quickly and eliminate most of the native animals and plants.
Rabbits might reproduce very quickly. A female might have from 15 to 30 babies each year. This large population pushes native plants to the certain areas. Also, rabbits often compete for shelter and food with native animals, which causes a quick decline in these native species. More importantly, European or common rabbits are one of the most popular causes of soil erosion in the environment as they tend to burrow and overgraze the ground, which leads many native species that heavily depend on the environment to trouble.
Kudzu has been traded between its original places (Pacific Islands, Eastern Asia) and Europe, North America as a plant for eating and gardens. They are an aggressive vine that is able to grow up to 25 cm per day and smother other plants. This stops these species from having adequate to sunlight. More importantly, Kudzu might kill mature plants and prevent native species from growing. As a result, the whole ecosystem structure is changed.
So, as well as looking into how to get rid of Japanese knotweed if you ever find it present, you should also stay aware of these five other invasive species should they ever appear.
