Three kinds of ants—fire, mad, and mongoose—a goldfish, an ocean tree, a red palm weevil, and the entire mongoose and heath family (except mongoose, a European mongoose) are some of these species. can be part of Spanish Catalog of Invasive Alien SpeciesIt is a fact that prohibits the possession, transportation and trade of it.
These species are considered invasive due to their very different ailments, and in some cases – such as those of ants – inclusions in the Catalogue appear before or shortly after they are detected, i.e. by prevention, by the coordinator of Life. The Invasaqua project of the Iberian Ichthyology Society, Frederic Casals’s photo.
Fire ants, crazy ants, or pharaohs arrive as stowaways via the wood trade or gardening, according to Casals, who is also a professor in the Department of Animal Sciences at the University of Lleida. guessing is “important” and they appear on lists.
1. Red palm aphid
about a giant insect A family of lice, 7 to 8 centimeters long, that has existed in Spain for decades and has destroyed palm trees in many places.
2. Mioporo
This tree As for the antipodes, they’ve been used in horticulture for years, so Casals stresses the importance of controlling species used in public works because sometimes there’s “not enough coordination,” says the expert.
3. Mongooses and meerkats
Another of the current problems with the trade associated with pet ownership is the number of animal samples, which some animal groups consider “petism” because they consider it excessive in this country. raccoon existing in Madrid.
mongooses and meerkats They can be kept as pets, and when grown and disturbed, they are often released without knowing what impact they will have on local biodiversity.
A close example of this species, the raccoon, “eats everything” (reptiles, amphibians and even insects) and “relatively aggressive” towards humans, mongooses and meerkats are likewise expected to cause a direct impact on native species when released.
4. Ants
Some species are considered potential invasive because it is not known exactly whether they will have an infestation. negative effectFor example, although the fire ant is stinging and poisonous, a direct effect on humans can be expected.
Some exotic species that have been in one place for years or decades, for example, begin to affect the environment somewhere. woundsdue to, inter alia, changes in climatic or land use.
5. Aquarium fish
This fish variety, which is often found in aquariums, was introduced to the Vallvidrera reservoir in Barcelona, which is part of the Sierra de Collserola Natural Park, which must be drained not only for this species, but also by various animals. other invaders like carp fish.
In this swamp, near the city of Barcelona, there are people who have left. fish, turtle or other animal It’s something that happens in many other aquatic ecosystems when they decide to stop owning them.
This Paramisgurnus dabryanuswidely known large scale teethit is not “more dangerous than any other”, but its inclusion in the official catalog has to do with the site it was promoted to.
The reservoir area is “very important” for protecting native amphibian populations, as defined by Nature Park managers who periodically empty the reservoir to eliminate these invasive exotic species that mostly prey on eggs, tadpoles and adults. amphibians.
The main problem is that this expert details, internet commerce, This allows you to buy any type of fish, even if it’s not “in theory” legal, taking advantage of the lack of control.
Although this particular species is already eliminatedCasals details what happened, as with many other fish in the tropics where there were sudden changes in water level: the specimens managed to bury themselves and hibernate in the mud.
