The 15 most worrying invasive species in Spain – Cotorra argentina

One of the main causes of biodiversity loss worldwide is invasive species. These animals come from different areas or continents, but enter the country intentionally, accidentally or artificially. After some time within the territory, they manage to adapt to the environment, displacing native species or ending them in the worst case.

In this way, many autochthonous species are in danger of extinction, since they cannot compete with the invaders as they have not grown together with them. In addition, according to the World Wide Fund for Nature, this problem represents an investment of 12,500 million euros a year for the European Union , in addition to environmental and health problems for citizens.

Among the most damaging species are some well-known ones, such as the Argentine parrot . This species was introduced to Spain through legal trade in 1980. Once inside, they began to escape from the cages and were even released due to the noise they caused in the houses . Currently they constitute a pest and are a danger to agriculture. Other species, such as zebra mussels , accidentally entered the Ebro basin, attached to the hulls of ships.

On the other hand, the Spanish Catalog of Invasive Exotic Species includes 197 species of plants, flowers, fungi and animals. Of these, 112 belong to birds, mammals, fish, reptiles or amphibians, among others. Thus, some species such as the Egyptian hedgehog, the raccoon, the Nile goose, the largemouth bass or the Japanese quail stand out.

Similarly, although different plans and strategies are being carried out to control and eradicate them, some of these species such as trout or red crab are being hunted or fished again , causing greater damage and favoring their reproduction. For this reason, it is essential to think about which animal we are acquiring , the care it requires as well as the possible consequences for the environment and ecosystems.
