Invasive species in Spain are a major driver of biodiversity loss in the country. Both intrusive creatures and plants are regularly introduced by people and pose a threat to local animal populations.
Meaning of invasive species in Spain
The recognized center of the International Union for the Conservation of Nature /IUCN, establishes that an "intruder species" is an external species that remains in a characteristic or semi-common environment or territory, becoming a specialist of progress and a danger to the organic variety.
In this way, intrusive species are those capable of effectively duplicating and shaping independent populations in an environment that is not their own. The moment this occurs, they are declared to have "naturalized", which can have dire ramifications for local species.
Some known non-native species cannot survive and reproduce on their own, so they eventually disappear from the environment and do not endanger local biodiversity. In this situation, they are not seen as intrusive species; they are simply present. They are among the species that enhance the environment, just like exotic species in Argentina.
Origin of invasive species
As the individual exists, it has made incredible movements and has taken with it species that have helped it endure. Route and transoceanic investigations greatly expanded the number of intrusive species.
In any case, the globalization of trade that has occurred during the last century has exponentially expanded both the introduction of species and the extinction of species.
Results of the entry of invasive species in Spain
The results of the presentation of intrusive species are not fast, however, they are seen when enough time has passed since their presentation, a part of these results are:
- Species elimination: species that are intrusive may end the presence of the creatures or plants they eat, as they do not adjust to the predation or enthusiasm of the new consuming agent. Furthermore, they go after assets (food, space) with local species, ultimately uprooting them and causing them to disappear.
- Environment setting: As a result of their action, they can change the evolved way of life, regular procedures, and the functioning of the natural environment and biological systems.
- Disease transmission: fascinating species transmit pathogens and parasites from their places of origin. Local species have never lived with these infections, which is why they frequently suffer a high mortality rate.
- Hybridization: some species presented can be replicated with different assortments or native races. As a result, the diverse local can disappear, decreasing biodiversity, which should be taken care of.
- Financial results: Numerous intruding species become crop bugs, crushing crops. Others are adapted to living in human foundations, for example pipes, causing extraordinary monetary misfortunes.
What are these invasive species in Spain?
In this article, we have to concentrate on invasive species in Spain, which from then on incorporate more than 100 species. All invasive creatures regularly adapt to different types of environments and foods, persecute local species, and compete for resources with creatures like themselves.
In addition, they can hybridize and transmit diseases. Do you need to know more? In this article you will see a part of the invasive species in Spain: Examples and results.
Invasive animals in Spain
Intrusive creatures in Spain are those that are built in characteristic or semi-normal spaces and that represent a danger to local biodiversity. Your place of birth shifts:
- Sporadic: when moving merchandise or individuals, as a rule through boats.
- Extraordinary Pets: Many people release quirky creatures that they keep as pets, either because they tire of them or because they believe they are accomplishing something worth being thankful for.
- In any case, they do not realize that they endanger the fauna of the Iberian Peninsula. Because of this, the dealing and acquisition of any of the creatures recalled for the Catalog of Invasive Alien Species is not permitted.
- Ranches: some fascinating animals are raised on ranches across the nation for their monetary use. The exemplary model is to establish the hidden ranches.
- Chase and fishing: numerous species, particularly fish and huge ungulates, turned up for hunting or fishing purposes. The Balearic and Canary Islands have countless intrusive creatures, many of which are native to the Iberian Peninsula. There, they cause terrible damage due to the great biodiversity of the islands and their endemism. Be that as it may, this article will focus on the intrusive creatures of the Iberian Peninsula.
Examples of invasive species in Spain
As you read you will realize which are those invasive species in Spain that are well known.
Wolf snail -Euglandina rosea
It entered some Pacific islands and India as a predator of another intrusive species: the prominent African Goliath snail/Achatina fulica. This had been featured as a food and pet resource in numerous nations, until it became a rural nuisance. True to form, the wolf snail devoured the Goliath snail, but the presence of numerous native types of gastropods ended.
Vietnamese pig – Sus scrofa domestic
Vietnamese pig is the assortment of local pigs usually raised in Southeast Asia. Due to their charming character and adorable appearance when they are almost nothing, these pigs became elegant as pets and reached all over the world.
In any case, when they grow up they become extremely large creatures and eat a lot, so they were abandoned as a group. From then on, numerous Vietnamese pot-bellied pigs have not been domesticated and roam freely through the mountains, like migratory animals.
It may sound nice, however, these ungulates are considerably more greedy than the wild members of their Iberian family, the wild pigs/Sus scrofa. In addition, they have doubled with them, offering to promote the supposed lechonlí and, in this sense, producing another intrusive species, and have called into question the survival of the Iberian pig as an assortment.
American mink – Neovison mink
The American mink is a semi-oceanic mustelid from North America. Its beginning in the Iberian Peninsula is the unloading of the leather ranches. Today, it is seen as one of the most reckless intrusive species in Spain. It is because of the way some exceptionally mined creatures are found among their prey, for example the Iberian desman /Galemys pyrenaicus.
In addition, this mustelid lives on the shores of swamps, streams and lakes and has a biological system similar to the European mink /Mustela lutreola, the polecat /M. putorius and the European otter /lutra. Due to its larger size and insatiability, the American mink could dislodge these different well-evolved creatures, despite infecting them with different diseases.
Boreal Raccoon – Procyon lotor
The northern raccoon is a warm-blooded animal of North American origin. Today, it is found in numerous European nations due to discharges or escapes from hidden ranches and from private homes that kept it as pets.
In Spain there are populations in the Community of Madrid, it has also been seen in Catalonia, Cantabria, Mallorca, the Basque Country, Galicia, Castilla-la Mancha. It is an omnivorous and inexhaustible creature that can eat everything from oak seeds to endangered creatures of land and water.
In addition, it adapts to any natural environment, despite the fact that riparian forests favor it, and it replicates quickly, having the option of having more than 10 offspring in a single litter.
Argentine Parrot and Kramer's Parrot
These species, such as the Argentine parrot / Myiopsitta monachus, which is native to South America, and the Kramer's parrot / Psittacula krameri, from Asia and Africa, are creatures of winged origin that have generally been used as pets.
Be that as it may, due to uncontrolled dumping or leaving the home, they have not been domesticated in numerous parks and agricultural lands close to urban communities. At this time, there are more than a thousand sets of the Argentine Parrot and many sets of the Kramer Parrot.
The results filed so far are damage to plants in nurseries and to crops in horticultural areas where they have been involved. Be that as it may, should they figure out how to fit into normal spaces, their quality may have genuine ramifications for local wildlife and vegetation.
Florida Slider -Trachemys scripta elegans
The beauty that springs from this renowned Florida Lake Terrapin or Red-eared Lake Terrapin originates from the southwestern United States, but has been dispersed throughout the world due to its treatment as a pet. Today it is registered as one of the most dangerous intrusive species in Spain.
This species has adapted to the waterways and lakes of the Iberian Peninsula. It is more established, lighter and more voracious than the local species, for example, the imperious figure of the European Lake Terrapin /Emys orbicularis or the Lake Terrapin /Mauremys leprosa.
The Florida tortoise rivals these species in an extremely convincing way, figuring out how to uproot them. In addition, it can infect them with pathogens and represents a danger to its prey, which does not fit its high insatiability.
Pike – Esox lucius
This species, even when it is not found in Spain, can be seen on the banks of the rivers in the Iberian Peninsula from the year 1.949 dedicated to fishing for sport. It takes advantage of its enormous weight to feed on animals without spines, on land and on those that are winged, it is very dangerous.
Asian hornet – Vespa velutina
The Asian hornet is a hymenopteran that begins in Southeast Asia. It was inadvertently introduced in France around 2004. In 2010 it was seen for the first time in Amaiur/Navarra and has spread throughout the north of the nation, from Galicia to Catalonia.
This species benefits from honey bees and different pollinators, thus adding to the rest of the pressure factors that are squeezing these creatures.
In addition, due to the lodging of bumblebees /Apis mellifera, they most often raid beekeepers' hives, causing unbelievable misfortunes. It is also recognized that the Asian hornet can supplant local wasps in their environments.
American Red Crab – Procambarus clarkii
It has been achieved in the waterways of Spain as a state of use for fishing, at present it has become a group of characteristic animals in all the waves of the country, including the usual habitats of the Doñana creature insurance shelter
This crab is bigger, more serious and insatiable than the European crayfish / Austropotamobius pallipes, which is one of the endangered creatures in Spain.
Local crab decay is mostly due to an infection known as aphanus mycosis. It is a fungus that traveled from North America to reach our waterways as a result of the introduction of non-local crabs.
Zebra Mussel – Dreissena polymorpha
This type of aquatic creature is a kind of freshwater clam that was sighted for the first time in 2001 precisely in the lands of the Iberian Peninsula, spreading through many streams, damaging the environment and, so to speak, creating financial problems.
Its young are planktonic, so it can be very well sent starting with one current and then to the next through the counterbalancing water present on the pontoons. Adults added to pontoons or kayaks can also introduce themselves. Therefore, the route of the waterways has greatly preferred its dispersal.
It is a species that has the potential to influence all the fauna and vegetation of freshwater biological systems. In this way, it is seen as one of the most harmful intruding species in Spain.
Adults spread every conceivable substrate, including the canals and shells of different molluscs. In addition, it benefits from phytoplankton, competing with endangered native clams, for example Margaritifera auriculars.
Caulerpa – Caulerpa taxifolia
Caulerpa is the most harmful intrusive plant on the planet, it is a tropical green growth that was known in the Mediterranean during the 80's, due to the release of water from an aquarium. Today it is found throughout the western Mediterranean, where it is a hazard to local grasslands, where various creatures breed.
Nile perch – Lates niloticus
These huge stream fish were brought to Lake Victoria in Africa. In a short period of time, they caused the decimation of more than 200 endemic fish species due to their predation and rivalry.
Exercises obtained from their fishing and utilization are also accepted to be identified with lake eutrophication and water hyacinth/Eichhornia crassipes intrusion.
