Spanish ecosystems threatened by invasive insects, fish and plants

More and more exotic species called exotics occur in Spain. They are animals and plants that did not originally occur in Spain, but ended up there through human intervention. Some foreign products are labeled as ‘aggressive’ because they are harmful to the environment. If the Spanish Ministry of Environmental Change is in charge, the possession, transportation and trade of certain invasive species will soon be banned.

‘Aggressive Exotics’ status

Meanwhile, the government has declared several species of ants, a fish, a plant and almost the entire family of mongooses and meerkats an ‘invasive alien’. If that status is recognized, the possession, transportation and trade of that species will be prohibited by law. The government hopes this will slow down the threatening plague of invasive species.

VN: The fire ant is progressing very aggressively

The Solenopsis invicta, Also known as the red fire ant, which is a small insect about 4 mm long, which already burns many itchy bumps. About 15 years ago the UN warned of the spread of this very aggressive ant that spreads at lightning speed. Also, they eat everything they encounter on their way; From cockroaches and beetles to dead snakes, plants and crops. They eat through the wiring of traffic lights and destroy entire crops. The economic damage is enormous. The ant, originally from Paraguay and Brazil, was first discovered in 2006 in Malaga. Here, an ant bite leads to a case of ‘anaphylaxis’, which causes serious side effects with severe allergic reactions. The fire ant could have ended up in Spanish territory via an imported tree.

It is best to save before coming

Aggressive ethnographers recommend a preventive approach. Adequate intervention before species spread is very effective and inexpensive. If this intervention is not done in a timely manner, it can have long-term consequences both economically and environmentally. For example, the red palm beetle has already caused great damage to Spanish palm trees. Insect is one of the top 10 most endangered species of invasive species in Spain.

The reservoir lake dried up by aggressive fish

A large reservoir in Valvitrera (Barcelona) was drained more than 2.5 months ago. Reason, ‘Clarity’ Paramiskurnus Tabrianus, An alien and aggressive species native to Southeast Asia. According to the Catalan government, this aggressive race has a ‘negative effect’ on other invertebrates in the environment and can seriously upset the balance. Species Parasites can be introduced into indigenous communities.

The reservoir eventually dried up for several months. The sludge had to be well dried, as the fish species could survive in the soil layer of the reservoir for up to two years while absorbing and filtering oxygen from the air. Unfortunately, once the project is completed, the fish are still found in the reservoir.

Most headaches about plant invasive species

While the Asian loch and the red fire ant are more imaginative, it is mainly the exotic, invasive plants such as ‘Pompas grass’ and ‘Big Loosestripe’ that cause headaches in Spain. This is how The Myoporum latteAlso known as the ngaio tree – an evergreen shrub from New Zealand – has now entered the Spanish coast. 10 years ago, the Spanish Ministry of Environment described the species as an ‘escaped garden plant’ that already appeared in abundance in the hills. Meanwhile, the expansionist drive of the occupation plant meant that Spain would have to pull all the stops to clear the coastal dunes of the species.
