E-book Invasive Species by Koidula Huvijuht

E-book Invasive Species

In the course of the International Comenius project " Invasive species- nature richness or damage" a considerable amount of research material on invasive alien species was gathered by the Estonian, Polish, Spanish, Italian and Turkish students. Based on this research material this e-book was compiled which gives description and deals with the subject of invasiveness, distribution paths and maps of invasive alien species as well as the methods applied to fight against these species.

Invasive Species Invasive species can be: Plants, fish, insects, mammals, birds, and even microorganisms. Invasive species are organisms that have been brought from outside of their native range and have had a negative impact on their new surroundings. They will likely cause economic harm, environmental harm, and even harm on human health. The term "invasive"; is used for the most aggressive species. These species grow and reproduce rapidly, causing major disturbance to the areas in which they are present. Invasive species often compete so successfully in new ecosystems that they displace native species and disrupt important ecosystem processes.

Poland Gimnazjum im. Jana Pawła II w Bedlnie

The Secondary School in Bedlno began its activity on 1. September 1999. On 18. May 2006 the school took name after John Paul II. The school banner was founded by the Council of Bedlno, and the parents. Its consecration was performed by Bishop J. Zawitkowski. In the years 1999-2012 the school was administrated by mgr inż. Jadwiga Gajewska. Currently it is managed by mgr Ewa Kowalska. The school creates respect for the common wealth of the local and national community, teaches patriotism and widely understood tolerance, and shapes moral sensitivity. In order to popularize the figure of the patron in our school and local environment we organize such celebrations as the Papal Day, the School Day on the anniversary of the election of Karol Wojtyła for the Pope, etc. Representatives of the school with the flagship troop participate in pilgrimages of the family of schools named after John Paul II to Częstochowa.

We are involved in many projects financed by the EU, e.g. the Comenius Programme, the Development Projects of Bedlno Community Schools, and The School of Dreams, within which we carried the programme “Swim out to Depths”. Taking part in the programme, pupils learned the message delivered by our great countryman. At present we are participating in the COMENIUS programme and in the project WFOŚiGW in Łódź - Arranging the Teaching Garden. Our students participate in different competitions, the Olympics and sport tournaments, achieving high positions. There are numerous organizations in our school: SKLOP, PCK, SU, ZHP, Caritas. Educational and tourist trips are often offered. So far the students have visited: Spain, Montenegro, Bulgaria, Greece, France, Estonia, Turkey, Italy. We have got 168 students at the moment and 17 teachers. We are comprehensive school. We teach subjects like: Math, Polish, English, German, Science, Biology, Technology, PE, Information Technology, Art, Physics, Religion, History, Geography. Our students are between 12-15 years old.

Turkey Iğdır Anadolu Lisesi

Iğdır Anadolu Lisesi is situated in Iğdır in the northeastern part of Turkey. As many other instutions in Iğdır, our school adopted the image of mount Ararat as its logo. Iğdır Anadolu Lisesi is just in the city center next to the national directorate of education. The school started in 1965. During the first years, it served as a presecondary school. After years passed, it turned into a general secondary school. Foreign Language based teaching direction started during 1995/1996 period and gave the last graduees during 2007/2008 educational period. And as it did at many other sports activity, IAL(Iğdır Anadolu Lisesi) witnessed being world’s best at folk dances in Djonne, France in 1992. Still while both struggling some impossibilities, IAL continues to attend sports events and win cups. The vision of our school is to enhance and guide the students with their correct answers instead of focusing on the mistakes, rewarding their success and positive behaviors, applying structure-based approach instead of rote-learning approach; helping them acquire lifelong absorptions and raising the individuals dependent on the reforms and principles of Mustafa Kemal ATATÜRK. The mission of Iğdır Anadolu Lisesi is to help all our students learn, help them develop their knowledge of the World, help them grow as self-confident individuals, 9

help them improve skills needed to strive in the 21st cdentury. Since the last two years, our school has been through the transition from double-shifting schooling to daylong schooling. And now we have 43 teachers, 16 classrooms and 992 students. The learning directions are equally-weighted direction; social sciences; Scientific-Mathematical direciton; and also once language based direction. Now in Turkey, as the system is changing each secondary school has its own study direction like science schools, social science schools, arts and sports schools etc. http://mebk12.meb.gov.tr/meb_iys_dosyalar/76/01/278810/ Telephone: +90 04762276924 Fax: +90 04762263882 Address: Söğütlü Mah.

Italy Liceo Scientifico "Giuseppe Tarantino"

Liceo Scientifico "Giuseppe Tarantino" is located in Gravina in Puglia (BA) Italy. It is named after the philosopher Giuseppe Tarantino born in Gravina in 1857 . He was Rector at the University of Pisa, Italy and he helped introduce American and European philosophy to the Italian educational system. The school was established in 1969 and it has made a lot of efforts since the beginning to meet the needs of the community. That is why it counts an ever increasing number of pupils. The school is located in a comfortable and large building, it has very good facilities : large classrooms, an indoor gym, science, physics, language and computer labs. The school plays an important role in the local area, ensuring the success of all young learners and welcoming students from abroad. It also promotes cultural events open to the community, acts as a key centre of information and education, organizing conferences jointly with the Local Authorities and cultural associations. The school gives to the young generation the chance to consolidate their basic cultural and social

skills, to record what they learn in order to be prepared either for university study or for work life. Today the school offers 5 courses : Scientific, Classical, Linguistic, IT and scientific, Musical The total number of students is 1200 , the teachers are 110. As partners in this project we intend to involve as many students and teachers as possible in order to draw their attention on this topical issue, driving them to research and discover the richness and uniqueness of our surrounding area, Alta Murgia National Park and Gravina Wood, raising awareness of the looming risks caused by the indiscriminate invasion of exotic species nowadays and in past periods as well. Through this European partnership the school and the community can develop their cultural growth and knowledge of other European realities, thanks to the benefits derived from shared experiences and mutual educational exchanges. Our school is going to contribute to the partnership, proceeding according to the following strategies: • Promoting and developing a culture of environmental care and protection; • Contrasting the existing indifferent attitude towards our surroundings ; • Giving the opportunity to students, parents, teachers and school staff to get in touch with European cultures, to find answers to common needs and develop common methods for the solution of problems; • Favouring the knowledge of our culture, customs and languages in different European schools; • Developing a common Environmental Agenda with the aim of motivating students to offer personal contribution as active individuals in view of a real enactment of the European Citizenship through the development of civic skills.

Spain INS Joan Mercader

The school is called INS Joan Mercader. Joan Mercader was a famous local historian. That´s why the school was named after him. It is a public High School situated in the center of Igualada, a small industrial town in the central part of Catalonia. Igualada has got 40.000 inhabitants approximately. Students have different socioeconomic origins, yet there are some of them who come from humble families. There are 62 teachers and over 600 students ,ages ranging from 12 to 18. Youngest students are 12 and when they finish ESO they are 16. That is compulsory for everyone! At Joan Mercader High School students can study ESO , that is “Educació Secundària Obligatòria”, which means Compulsory Secondary Education. And after that, it is possible to study batxillerat, ( non-compulsary studies after the ESO ). Batxillerat lasts for two years and there are different branches: science, technology, humanities, social studies and art. There are compulsory subjects such as: Catalan language and literature, Spanish language and literature, English language,PE, Philosophy, Science for public understanding, Tutorial Session. 13

There are optional subjects depending on the type of batxillerat the students have chosen: Scenic Arts, Audiovisual Culture, Musical Analysis and Graphic –plastic Techniques, History, Latin, Universal Literature and Spanish Literature, Biology, Mathematics, Chemistry and Physics. The school is the only state school in the area where students can study art, music and dancing. The school has already taken part in Comenius projects within the European Union framework. During the school years 2002/2003 and 2003/2004 with the project called “ Nature and Culture ” together with a school in France, one in Germany, one in Denmark and one in Rumania. And during the school years 2005/2006 , 2006/ 2007 and 2007/ 2008 our school has been the coordinating school for the project “Don Quixote travels throughout the Comenius territory ”.The schools which took part in this project were schools from France, Germany and Denmark. And at the moment school is carrying out two Comenius projects. One is about the ecological footprint and our partners are The Netherlands, Norway, Germany and France. And the other one is about invasive alien species with schools from Estonia, Turkey, Poland and Italy. Moreover, the school have pupil exchanges with Germany and France every year. The purpose of an exchange is multifaceted. The most obvious aim is to increase the motivation, capacity and confidence of pupils to communicate in other European languages. The exchange experience certainly gives the participants the opportunity to use the foreign language in an authentic setting; but also significant for the “visiting” exchange is the intercultural experience through living in another country, preferably within the domestic culture of a family.

American mink The species was examined by Estonia where it is called Ameerika naarits. 1. Taxonomy - Species: Mustela vison - Family: Mustelidae - Order: Carnivora

2. Description

http://www.animalspot.net/wp-content/uploads/2011/06/american-mink-facts.jpg

The American mink has a long body, and a streamlined shape, which helps to reduce water resistance while swimming. The American mink is similar in build to the European mink, but the tail is longer. The American mink's winter fur is denser, longer, softer, and more close-fitting than that of the European mink. The American mink relies heavily on sight when foraging. Its eyesight is clearer on land than underwater. The

American

mink

usually

has

4-9

cubs.

The American mink replaces the European mink by killing them wherever their ranges overlap. Mink prey on water birds, small mammals and fish. The American mink often carries light tick and flea infestations. 21

3. Distribution map http://www.europe-aliens.org/speciesFactsheet.do?speciesId=52880

They mostly spread in Northern and Middle Europe, also they can be found on Iceland, in Britain, France, Spain, Italy, Macedonia and Serbia. 4. Pathways Mink originally come from North America, however, in Estonia it was first seen in the 60s. Today, American mink are alien species which are spread all over Europe.

5. Spreading prevention methods and measures Physical Control: Live-trap and shooting, kill-trapping, snares and use of dogs. Biological Control: Native predators may assist in mink control (e.g. European otter, European polecat).

American Pekin duck The species was examined by Turkey where it is called Pekin Ördeği. 1. Taxonomy - Species: Anas Platyrhynchos Domestica - Family: Anatidae - Order: Anseriformes

2. Description I'm The Pekin duck, is a breed of domestic duck used primarily for egg and meat production. It was bred from the Mallard in China. Fully mature adult Pekin ducks weigh between 3.6 and 5 kilograms in captivity. Their average lifespan is about 9 to 12 years. Their external feathers are white, sometimes with a yellowish tinge. They have orange bills and orange legs. An adult Pekin will lay an average of 200 eggs per year, their reproduction is pretty high. The problem is that people prefer this duck and quit breeding other ducks. This problem causes the loss of native species. The problem does not only have the ecological dimension but health as well. During the year’s avian flu, it was noted that this duck spreads the virus and while it resist the virus other birds die. Even people were affected by the virus all over the World.

3. Distribution map

http://f.tqn.com/y/birding/1/S/i/L/-/-/Mallard.jpg From this map, it is possible to see the range of the distribution area.

4. Pathways A small number of ducks were imported to Oceania from China and from there to Long Island in 1873. They came to Turkey in 1874. 5. Spreading prevention methods and measures The most effective way to control the spread of the species is to use them less in agriculture and eradicate some animals in case of a serious outbreak.

Black slug The species was examined by Poland where it is called Pomrów czarniawy. 1. Taxonomy - Species: Limax cinereoniger - Family: Limacidae - Order: Limacoidea

2. Description

http://upload.wikimedia.org/wikipedia/commons/1/16/Limax_cinereoniger.jpg The size of the slug varies from 10 to 15 cm. Maturity is reached at about 2.5 cm. The color of the black slug is generally deep black, but the coloration is very variable and this slug can even be white. The slug covers itself in a thick foul-tasting mucus which serves as both protection against predators as well as a measure to keep moist. It is somewhat difficult to wash off. It can be found in thickets, forests, parks, gardens, but also close to home, plastic tunnels and greenhouses. The number of the black slug is 25

rising. Because of the black slug, our native snail species are dying. It is very harmful to crops, farmers are trying to fight it. 3. Spreading map

The black slug species is a relatively new inhabitant in Poland.

http://www.discoverlife.org/nh/maps/Mollusca/Gastropoda/Pulmonata/Limacidae/Limax/map_of_Limax_cinereo niger.jpg

It spreads mostly in the Northern, South-East and South-West Europe. 4. Pathways The slug originates from the South-West Europe.

5. Spreading prevention methods and measures The population of black slug should be limited by using natural enemies. The destruction of their shelters and drying areas near crops is also useful.

Blue crab The species was examined by Italy, where it is called Granchio blu. 1. Taxonomy - Species: Callinectes Sapidus - Family: Portunidae - Order: Decapoda

2. Description

The Blue Crab is an omnivorous animal and since it was introduced in our seas, it has started to eat everything it could catch. Blue crabs may grow to a carapace width of 230 mm. Individuals exhibit sexual dimorphism. Males and females are easily distinguished by the shape of the abdomen and by color differences in the claws. Sometimes when the species is in a favorable environment, its numbers get out of control, leading to disrupting the entire ecosystem. Female blue crabs only mate once in their lifetime. Up to two million eggs may be produced in a single brood, and a single female can produce over 8,000,000 eggs in her lifetime. It is very difficult to control the distribution of aquatic invasive species and prevent their spread once they have become established in the area. 28

3. Distribution map

4. Pathways The blue crab is native to the waters of the western Atlantic Ocean and the Gulf of Mexico. It has been introduced via ballast water to Italian and European waters, and it has been observed also in the Baltic, North, Mediterranean and the Black Sea. They were first found in European waters in 1901.

5. Spreading prevention methods and measures

Physical Control: Management of ballast water and cleaning ship hulls can be considered as prevention measures against the blue crab. Eradication, control, and monitoring efforts is used to fight the invasive species. Biological Control: Specific fish may reduce population density and slow down the speed at which it spreads naturally, but it is not an effective control method.

Brown rat The species was examined by Poland, where it is called Szczur wędrowny. 1. Taxonomy - Species: Rattus norvegicus - Family: Muridae - Order: Rodentia

2. Description

One of the largest muroids, it is a brown or grey rodent with a body up to 25 cm long, and a similar tail length; the male weighs on average 350g and the female 250g. The brown rat lives wherever humans live, particularly in urban areas. Similar to other rodents, brown rats may carry a number of pathogens, which can result in disease. Surveys and specimens of brown rat populations throughout the world have shown this species is often associated with outbreaks of trichinosis. Aside from spreading diseases, rats often pollute their living areas, and are considered pests.

3. Spreading map

Poland’s spreading map

Thought to have originated in northern China, this rodent has now spread to all continents, except Antarctica, and is the dominant rat in Europe and much of North 31

America—making it, by at least this particular definition, the most successful mammal on the planet after humans.

4. Pathways By the 20th century, it was established among naturalists that the brown rat did not originate in Norway; rather the species came from central Asia and China. Despite this, this species' common name of "Norway rat" is still in use today.

5. Spreading prevention methods and measures The best ways to fight the Norwegian rat is to protect buildings by limiting access to food, and setting traps. They have natural enemies, such as foxes, snakes.

Canada goldenrod The species was examined by Poland, where it is called Pomrów czarniawy. 1. Taxonomy - Species: Solidago canadensis - Family: Asteraceae - Order: Asterales

2. Description

The plant is erect, often forming colonies. Flowers are small yellow heads held above the foliage on a branching inflorescence. Canada goldenrod is sometimes browsed by deer and is good to fair as food for domestic livestock such as cattle or horses. It is found in a variety of habitats, although it is not shade tolerant. It typically is one of the first plants to colonize an area after disturbance (such as a fire) and rarely persists once shrubs and trees become established. It is found neither in very dry locations nor in waterlogged ones. It spreads very quickly, and is difficult to destroy.

3. Distribution map Poland’s spreading map

4. Pathways It comes from North America, and came to Poland from England in 1965. It occurs throughout North America, in most US states and Canadian provinces. In many parts of Europe, Japan and China, it is established as an invasive weed. In eastern and southeastern China, particularly the provinces of Zhejiang, Jiangsu, Jiangxi and Shanghai, its invasion has reached pandemic levels and has caused widespread concern. 5. Spreading prevention methods and measures Digging up particular bushes while they aren’t numerous yet, and mowing the plant before it flowers appear to be the best methods of preventing its spreading.

Colorado potato beetle The species was examined by Estonia, where it is called kartulimardikas, and by Poland, where it is called Stonka ziemniaczana, and by Turkey where it is called Patates Böceği. 1. Taxonomy - Species: Leptinotarsa decemlineata - Family: Chrysomelidae - Order: Coleoptera

2. Description

http://www.vegetablegardener.com/assets/uploads/posts/5301/Colorado_potato_beetl e.jpg It is approximately 10 millimetres long, with a bright yellow/orange body and five goldn brown stripes along the body. Beetles have a huge impact on crop. They can lay as many as 800 eggs. When their eggs have hatched the larvae chew small holes on the lower surface of the same leaf were the eggs were. The top of the leaf remains. The larvae climbs on top of the plant and eats the younger leaves, leaving the edges of the leaves indented, however, the beetles make larger holes on leaves. Crop Loss in Western European countries could reach an estimated (about) 5 ... 20%. Sometimes even to 80% or 90%

3. Distribution map

http://www.agroatlas.ru/en/content/pests/Leptinotarsa_decemlineata/map/

Distribution in Turkey.

4. Pathways Colorado potato beetle was brought to Europe from North America by ships across the Atlantic Ocean. At that time, we managed to block their spread, however during the World War I & II the control and eradication of Colorado potato beetle weakened and beetles came to the European areas. They came to Estonia in 1965 and to Turkey 1963.

The potato beetle spreads widely over the USA, Europe and Asia.

5. Spreading prevention methods and measures Physical Control: Picking by hand in small gardens can be effective. This method might be unpractical in larger gardens. Biological Control: Natural enemies - Ladybugs and Stink bugs. Sanitation: When the Colorado potato beetle comes in spring they will seek out alternative host plants, removing them from the garden as a possible food source. Planting an early maturing potato plant variety can help. Microbial: Bacteria can control young beetle larvae population. Such pesticides should be applied frequently.

Giant reed The species was examined by Spain, where it is called Caña común or Canya de Sant Joan. 1. Taxonomy - Species: Arundo donax - Family: Poaceae - Order: Poales

2. Description

http://www.arizonensis.org/images/plantae/arundo_donax.jpg

It is a perennial herbaceous hydrophytic found in wetlands in many climatic zones. It can grow up to 10 m in height. The numerous leaves are about 5 cm wide and 30.5 to 61 cm in length, are arranged in two opposite rows well in the stems, and have sharp margins. Has a strong and deep root rhizomes that allow it firmly and resist the force of rushing water while moving itself to any possible competitor. The stems and leaves contain a range of chemical pollutants, which probably served as protection of native insects and other herbivores. The giant reed invades a lot of edges of water, both natural and artificial. It grows very fast. It forms extensive monospecific plant mass, 38

which aggressively excludes competitors for light, nutrients and water. The occupied areas show a depletion of wildlife. The water is warmer in the habitats invaded, causing lower oxygen concentration and reducing biodiversity. Giant reed appears to be highly adapted to fires; it can increase the probability, intensity, and spread of wildfires through the riparian environment, changing the communities from flood-defined to fire-defined communities.

3. Distribution map

It spreads in Northern and Southern America; Southern Europe; Northern, Southern and Eastern Africa; Arabia; Asia; Australia and Oceania. 4. Pathways Giant reed is originated in Asia. Some suggest that it ranged from Asia throughout the Middle East, Southern Europe and Africa, and was introduced to the U.S. from the Mediterranean region in the early 1800. Joan

Hungarian wild boar The species was examined by Italy, where it is called Cinghiale ungherese. 1. Taxonomy - Species: Sus Scrofa Linnaeus - Family: Suidae - Order: Artiodactyla

2. Description

The Hungarian wild boar is a crossbreed between Sus Scrofa Majori and Sus Scrofa Attila. It has a compact body, large head, relatively short legs, and dense fur. They move around in groups of about twenty members. They measure from 90 to 200 cm in length, wild boars have sharp tusks bent upwards. The purpose was to repopulate the woods for hunting reasons. The Hungarian wild boar is more aggressive and gives birth up to 8 piglets. Hungarian wild boars bring about problems connected with agriculture, car accidents and the whole environment.

3. Distribution map It spread widely in Europe and Asia, it also spreads in Northern Africa.

4. Pathways It is a new species of wild boar coming from Hungary and it was introduced in the 1960s. Nowadays it populates most of Europe and Asia.

5. Spreading prevention methods and measures Physical Control: The most efficient way to eradicate Hungarian wild boars is by trapping the group of pigs one at a time. Trapping takes a lot of time, effort and money because boars are very wary and need to be slowly baited in and accustomed to the trap. Hunting is an inefficient and ineffective way to control or eradicate a population of Hungarian wild boars because the boars have a high survival and reproductive rate.

Indian meal moth The species examined by Estonia, where it is called Lõuna Aida-leedik. 1. Taxonomy - Species: Plodia interpunctella - Family: Pyralidae - Order: Lepidoptera

2. Description

http://entnemdept.ufl.edu/creatures/urban/stored/indianmeal_moth.htm The Indian meal moth adults are about 1/2 inch long with a wing span of about 16-20 mm. The forewings of this moth are reddish brown with a copper sheen on the outer two thirds and gray on the inner third. At rest the wings are held roof-like over the body. The head and thorax of the moth appears gray and the posterior brown, with a coppery sheen. The Indian meal moth is a very common household pest, feeding 42

principally on stored food products. Most of the "damage" to stored products occurs when the larvae spin massive amounts of silk that accumulate fecal pellets, cast skins, and egg shells in food products. They can come with flour, raisins and other, dried fruits.

3. Pathways The Indian meal moth probably made its way to Estonia with different food products transported to Estonia.

4. Spreading prevention methods and measures Chemical: Using sprays. Apply chemical insecticides to all the cracks and crevices of the shelves and cupboards to prevent future infestations. Non-chemical: Put all the dry and bulk food into a tight fitting containers. Clean shelves on a regular basis. Do not buy food in damaged packages. Do not mix new and old food to avoid infestation of fresh foodstuff. Traps: Perfect solution. Placing pheromone impregnated glue strips on a cardboard or paper. The pheromones attract male moths and trap them making mating impossible.

Monk parakeet The species was examined by Italy, where it is called Parrocchetto monaco and by Spain where it is called Cotorra Argentina.

1. Taxonomy - Species: Myiopsitta monacus - Family: Psittacidae - Order: Psittaciformes 2. Description

Monk parakeet is a small bright green parrot with a grey breast and greenish-yellow abdomen. Its natural habitat varies from plains to forests. The species is a very fast flier. The parakeet is 29 cm long on average, with a 48 cm wingspan, and weighs around 100g. It is particularly suitable as a pet; it is playful, lively, and intelligent - it can even learn to talk. It eats berries, flowers, seeds and fruits. The monk parakeet, as an invasive species, has become a problem to local fauna such as pigeons and sparrows, but not yet so harmful to magpies. Parakeets have also caused trouble to agriculture near the cities. The birds build huge nests that can weigh up to 150-200kg and can host till 20 couples of birds. Those nests cause significant weigh damage to the trees they 44

occupy. By building those huge nests, the parakeets systematically destroy vegetation. Barcelona has the greatest population of monk parakeets in Europe.

3. Distribution map

http://www.oiseaux.net/maps/images/conure.veuve.png

It spreads mostly in Northern and Southern America, it also spreds in Asia and Southern Europe. 4. Pathways It’s native of South America. Its natural area includes central and North-Eastern Africa, Afghanistan, western Pakistan, India and Nepal, as far as the centre of Burma and Ceylon. They were first sighted in both Italy and Spain in 1975. 5. Spreading prevention methods and measures So far, there have been no local bans or eradication programs against the monk parakeet, presumably because their settlement in urban areas does not pose an immediate threat to agricultural production.

Mosquito fish The species was examined by Turkey, where it is called Sivrisinek Balığı.

1. Taxonomy - Species: Gambusia Affinis - Family: Poeciliidae - Order: Cyprinodontiformes

2. Description

http://www.sccgov.org/sites/vector/PublishingImages/mosquitofish-R.jpg

Mosquito fish are small in comparison to other fish, with females reaching an overall length of 7 cm and males a length of 4 cm. Mosquito fish are small dull and grey, with large abdomen. They have rounded fins and an upturned mouth. Mosquito fish were introduced directly into ecosystems in many parts of the world as a biocontrol to lower mosquito populations, which in turn negatively affected many other species in each distinct bioregion. Mosquito fish eats the larvae of the mosquitoes but also the eggs of other fish. It is aggressive and it attacks other fish fins, it also competes with other local fish for food.

3. Distribution map

They spread in Southern Europe, Africa and Australia. 4. Pathways The mosquito fish is one of the species with the widest range of introductions. The species has been transported to every continent to control mosquitoes and it has thus acquired a near global distribution. In the DIAS recordings this species was thrown into Turkish waters on an unknown date and thus the population of this fish was created. These introductions began approximately 100 years ago.

5. Spreading prevention methods and measures Physical Control: Draining water and leaving the area dry for a few days. Polypropylene barrier fencing material can be used in order to isolate certain springs from mosquito fish. Gambusia can be effectively removed from small springs using netting techniques. In larger spring environments, chemical removal of the species may be the most efficient method. Biological Control: Natural predators help containing the spread of the species. Chemical Control: Poisoning the fish (most effective when water temperatures are above 25°C), applying a dose that won’t kill quickly is preferred; when the fish come to the surface to breathe, the untargeted species can be caught and saved. 47

Proposals by survey: Minimizing further human dispersal of mosquito fish through implementing enhanced government regulation, and public education and awareness campaigns.

Nutria The species was examined by Turkey, where it is called Su İti.

1. Taxonomy - Species: Myocastor Coypus - Family: Myocastoridae - Order: Rodentia

2. Description

http://upload.wikimedia.org/wikipedia/commons/d/da/Myocastor_coypus_-_ragondin.jpg

Nutria is a large herbivorous semiaquatic rodent and the only member of the family Myocastoridae. They somewhat resemble a very large rat, or a beaver with a small tail. Adults are typically 4–9 kg in weight, and 40–60 cm in body length, with a 30 to 45 cm tail. Nutria are rodents that are more agile in the water than on land. They live in burrows, or nests, never far from the water. They are strong swimmers and can remain submerged for as long as five minutes. These animals mature quickly and remain with their mothers for only a month or two. In some areas, booming nutria populations have become troublesome as the animals develop a taste for farm fare. The 49

Nutria is too efficient at eating, which is threatening habitats, native plants and other wildlife. Their high reproduction rate and resulting overpopulation is stretching limited trophic resources and threatening other species such as waterfowl and muskrats. Nutria also carry and transmit various parasites and diseases.

3. Spreading map

http://www.europe-aliens.org/images/factsheetMaps/24_myocoy.jpg

It spreads in the USA, Southern America, most of the Asia and Europe and a few countries in Africa.

4. Pathways This species is native to South America, and has been introduced to North America, Europe, Africa, and Asia. Its distribution in the Patagonian steppe is likely the result of human introduction. The original range of nutria was south of the equator in temperate South America.

5. Spreading prevention methods and measures Cultural ways: Draining the water, eliminating bushes, trees, thickets, and weeds from fence lines next to ditches, drainages, waterways, and other wetlands to discourage nutria. Chemical: Using rodent repellents and liquids that simply taste bad. Those will stop most animals from eating any plants. Physical Control: Using traps or just shooting the animals has proven to be very effective.

Red-eared slider The species was examined by Spain, where it is called Tortuga de Florida. 1. Taxonomy - Species: Trachemys Scripta Elegans - Family: Emydidae - Order: Testudines

2. Description

http://en.wikipedia.org/wiki/Red-eared_slider#/media/File:RedEaredSlider05.jpg

It is characterized by an intense red spot which is located between the back of the eyes and neck. The limbs are robust and webbed. The turtle can reach a maximum size between 20 and 60 cm depending on the subspecies. The carapace of this species can reach up to 30 cm in length, but the average length ranges from 12 to 20 cm. The females of the species are usually a little 52

larger than the males. The shell is divided into two sections: the dorsal carapace that consists of the vertebral scutes and the ventral carapace called plastron. They can live between 20 and 30 years (less in captivity). The species competes with native Iberian turtles: it reaches larger sizes, produces more offspring, reach sexual maturity sooner, and have a more varied diet. They can survive in conditions other turtles can’t such as pollution and human presence. They exclude other freshwater habitants by competing for food and breeding ground. Red-eared sliders brumate (they become less active) over the winter at the bottom of shallow lakes, when T falls below 10 °C, and can survive anaerobically for weeks. After mating, the female can lay between two and 30 eggs. They live in areas of calm water, but not closed, where they climb onto rocks or tree trunks. Turtles are poikilotherms, (unable to regulate their body T°C), for this reason, they continually need to sunbathe. If their body T falls below a 21°C, they are unable to carry out normal functions.

3. Distribution map

It spreads mostly in Northern America but also in Southern America. It also spreads in Britain, Spain, Morocco, Angola, Indonesia, Korea, Japan and a few other places in Europe and Asia.

4. Pathways It came to Europe from the USA. Their native areas include the southeast of Colorado, Virginia, and Florida. Feral populations of red-eared sliders are now found in Australia, Europe, South Africa, the Caribbean, Israel, Bahrain, Mariana Islands, Guam, and southeast and far east Asia.

5. Spreading prevention methods and measures Their import has been banned by the European Union and specific member countries. Physical control: The species can be controlled by hunting, trapping, and collecting eggs and hatchlings. Oddly enough, these methods have proved so effective that there is some worry that overhunting within its home range is leading to a decline in the species where it is supposed to be. A better solution to population control in urban areas would be capture- sterilization- release.

Red palm weevil The species was examined by Italy, where it is called Punteruolo rosso.

1. Taxonomy - Species: Rhynchophorus ferrugineus - Family: Curculionidae - Order: Coleoptera

2. Description

The adult beetles are relatively large, ranging between 2 and 5 cm long, and are usually of rusty red colour, many colour variations exist and have often been misidentified as different species. This weevil usually infests palms. While the adult causes some damage through feeding, it is burrowing of the larva into the heart of the palm that can cause the greatest mortality of trees. The first symptoms are represented by an anomalous behavior of the hair, giving it a distinctive appearance retracted "to open umbrella." In more severe cases it gets to the complete loss of the leaves, so the plant appears as "cut down". In the terminal stage of infestation it produces a real "collapse" of the plant: only at this point weevils colonies abandon the plant attacked by migrating on a new specimen. After fertilization, the adult female can lay between 300 and 500 eggs. This means that the insect also has the ability to reproduce quickly. 55

2. Distribution map

Distribution in Italy.

Distribution in the world. 4. Pathways The red palm weevil is native to Southeast Asia and Melanesia. As a result of trade in specimens of infected palms, it reached the United Arab Emirates in the eighties and from there spread to the Middle East, and to almost all the countries of the southern Mediterranean Sea. They came to Spain in 1992. 56

5. Spreading prevention methods and measures Physical Control: Burning infected plants. An Italian company has developed a microwave collar that can be used to sterilize individual trees. Chemical control: The main control method is through the application of a systemic insecticide. New alternative technologies using semiochemicals and bio insecticides are being developed to more effectively control this devastating pest of palm trees.

Red swamp crayfish The species was examined by Spain, where it is called Cangrejo rojo or Cangrejo Americano. 1. Taxonomy - Species: Procambarus clarkii - Family: Cambaridae - Order: Decapoda

2. Description

http://upload.wikimedia.org/wikipedia/commons/thumb/1/1a/Procambarus_clarkii.jpg/220pxProcambarus_clarkii.jpg

This crayfish has a diverse coloration red (adults) to brown and green (youngsters). The head is shaped by two cylindrical plates and front; two antennas are used to detect their food and two clamps are used to capture prey and defend against potential attackers. It can weigh up to 50 g, and measure 5.5–12 cm long. Its average lifetime is five years. It is commonly found in warm fresh water, such as slowly flowing rivers, marshes, reservoirs, irrigation systems and rice paddies. It is considered to be the most ecologically plastic species in the order Decapoda, and is 58

able to grow quickly even in only seasonally present water, it is also able to tolerate slightly saline water, and are physiologically adapted to tolerate relatively low oxygen concentrations. The red swamp crayfish has caused lots of negative effects around the world: It damages the course of the rivers and rice crops, it has exterminated the native crab, it destroys the local flora, and it hurts other animals and eats its offspring. After fertilization, female lays between 200 and 900 eggs.

3. Distribution map

http://www.europe-aliens.org/images/factsheetMaps/66_procla.jpg

It mostly spread in Spain and Portugal, but also France, Italy, England, Netherland, Germany, Switzerland, Austria. 4. Pathways The red swamp crayfish is native to the North-East Mexico and South-East USA, but found also in other continents, where it is often an invasive pest. The red crab was introduced in 1974 for commercial purposes by fishermen. The first introduction 59

occurred in the Lower Guadalquivir marshes, on the farm called "Casablanca" of Sevilla. It was introduced to replace Iberian populations of crabs. Since 1979 the fishing is done for commercial purposes. Spain is among the top three areas that contribute to global market.

5. Spreading prevention methods and measures Biological Control: Populations may be controlled by natural predators such as cormorants, crows, herons, storks, eels, perch, otters and racoons. Manual Control: Crayfish traps, large nets, and electro-fishing are the most common ways of catching Crayfish. Cultural Control: Educating people so the domesticated crayfish couldn’t escape or be set free. Chemical Control: Best biocides used for the controlling of the species are organophosphate, organochlorine, and pyrethroid insecticides.

Round goby The species was examined by Estonia, where it is called Ümarmudil.

1. Taxonomy - Species: Neogobius melanostomus - Family: Gobiidae - Order: Perciformes

2. Description

http://www.outdoornews.com/December-2013/Dead-goby-found-in-Susquehanna/

Round goby is quite a small fish whose length varies from 12 cm to 25 cm. Round goby is a really aggressive fish and is capable of crowding out other fish from their habitat. They also eat other fish eggs and food. These fish can change the marine

spineless community composition and structure, and also the material cycling in whole marine ecosystem.

3. Distribution map

http://www.europe-aliens.org/pdf/Neogobius_melanostomus.pdf

It’s mostly spread in the Baltic sea. 4. Pathways Round goby came from the Black, Caspian, Azov and Marmara Sea. They most likely traveled with ships' ballast water. Also, this fish was brought to the Baltic Sea in ballast water containers: probably, the fertilized eggs or very young fish got into the ballast water. 5. Spreading prevention methods and measures The best way to fight the spread of this species is to contribute by never using round goby as bait, and never putting the fish or its eggs into lakes, rivers or streams.

Sosnowsky's hogweed The species was examined by Estonia, where it is called Sosnovski karuputk and by Poland where it is called Barszcz Sosnowskiego. 1. Taxonomy - Species: Heracleum sosnowskyi - Family: Apiaceae - Order: Apiales

2. Description

http://www.looduskalender.ee/node/10580

Sosnowsky's Hogweed reaches up to 3–5 meters in height with a straight, solid stem that can reach a diameter of 12 cm. The leaves are 50–60 cm long. The root is quite solid , reaching up to 30 cm in diameter. The species is named in the honor of the Russian botanist Dmitry Sosnovsky.All parts of Sosnowsky’s Hogweed are toxic. It is dangerous for humans because even small drops of the plant's juice cause photosensitivity (light sensitivity) and burns. The plant is less dangerous for animals that have thick hair to protect them from the sun.

3. Distribution map

http://www.europe-aliens.org/images/factsheetMaps/6_herman.jpg

It spreads mostly in the Western- and Middle-Europe, also Northern-Europe and Russia. 4. Pathways Sosnowsky's Hogweed is a flowering plant originally native to Caucasus. Now it is a common weed in the Baltic States, Belarus, Russia, Ukraine and Poland. The plant was once common only in the Caucuses area, however due to a decision to use it as a farm animal feed (silage) plant, it quickly spread in many areas of Russia, Belarus and Ukraine.

5. Spreading prevention methods and measures Digging: Works on plants in their first or second year of growth. Effective in the spring (early May). Remove with spade taproot. Covering the dug area with black plastic.

Tilling: Effective on agricultural land and near residential areas where conditions may be more favourable. Flower removal: In summer before seed production will stop the plant from reproducing. Must be repeated over the summer . The cut umbels must be collected and destroyed. This method is not recommended. Chemical: Effective in spring. New seedlings will often germinate from seed and emerge after glyphosate applications have occurred.

Tiger mosquito The species was examined by Spain, where it is called Mosquito Tigre. 1. Taxonomy - Species: Aedes albopictus - Family: Insect - Order: Diptera

2. Description

http://upload.wikimedia.org/wikipedia/commons/e/ea/Aedes_Albopictus.jpg

The Asian tiger mosquito is about 2 to 10 mm in length. It has black and white striped legs, and a small black and white striped body. Tiger Mosquitos usually live in areas next to the sea, rivers or lakes and make their nests in holes inside the trees, in outsider water superficies, etc. Only females require a blood meal to develop their eggs. At the moment, there are no effects among other mosquito species, but their bites are somewhat different from the ones by other species; they are bigger, more stinging and 66

more abundant. The tiger mosquito bite is not unlike other mosquito bites. However, it is a mosquito that bites during the day and causes discomfort because of the large number of bites it does, after all, it is not a health hazard. Mosquitoes are means for spreading diseases such as malaria, dengue, and yellow fever.

3. Distribution map

http://www.europe-aliens.org/images/factsheetMaps/41_aedalb.jpg

It spreads in Spain, Italy, Slovenia, Czech, Croatia, Bosnia and Herzegovina, Montenegro, Albania, Germany and Netherlands. 4. Pathways It is native to the tropical and subtropical areas of Southeast Asia. In Europe it is mostly spread around the Mediterrean Sea.

5. Spreading prevention methods and measures Biological Control: Natural enemies, such as other mosquito larvae, flatworms, swimming beetles, fungi, and spiders. Physical Control: The control of the tiger mosquitoes begins with destroying the places where they lay their eggs. Chemical Control: Bodies of water periodically treated with properly labeled insecticides or Bacillus thuringiensis israelensis (bacterium that produces toxins which are effective in killing larvae of mosquitoes and certain other Dipterans, while having almost no effect on other organisms) aid in the fight against the tiger mosquito.

Tree of heaven The species was examined by Turkey, where it is called Cennet Ağacı and by Italy, where it is called Ailanto.

1. Taxonomy - Species: Ailanthus Altissima - Family: Simaroubaceae - Order: Sapindales

2. Description

The bark is smooth and light grey, and it has compound leaves. The tree grows rapidly and is capable of reaching heights of 15 meters in 25 years. It spreads via suckering ability and seeds as well. A common tree in urban areas where it causes damage to sewers and structures, ailanthus poses a greater threat to agriculture and natural 69

ecosystems. It spreads fast and has many seeds at a time, which establishes dense stands that push out natives. Tree of heaven contains chemicals, including ailanthuses that have been found to have strong allopathic effects on the growth of other plants which

has

become

invasive

specieshttp://en.wikipedia.org/wiki/Invasive_species due to its ability both to colonize disturbed areas quickly and to suppress competition with allopathic chemicals. The tree also re-sprouts vigorously when cut, making its eradication difficult and time consuming. In Italy it was used in reforestation for the consolidation of unstable areas and landslides in bank protection of watercourses subject to flooding and to improve soil fertility.

3. Distribution map

It spreads wildly over the Western, Southern and Eastern Europe.

Distribution in Turkey.

4. Pathways Tree of Heaven is native to China and Taiwan. The tree was first brought from China to Europe in the 1740s and to the United States in 1784. In Europe, it spread to the Mediterranean basin. From there also to Argentina, Australia, New Zealand, Asia, Pakistan, and North America. It came to Italy in 1760.

5. Spreading prevention methods and measures

Biological control: Fungal pathogens, and parasites.

Manual control: The best way is to pull the young plant out of the moist soil with its roots. Chemical: Basal Bark application, hack-squirt application, tree stump poisoning. (In case of re-sprouting, repetition of this procedure is needed. The poison should only be applied on the tree. Spreading can cause other plants to die), herbicide pellets (granular or round shaped herbicides are scattered around the roots of the unwanted plants when rain is close. Other plants may be affected). Cultural ways: It is stressed under shade. Grass sod will help shade out and discourage the tree. Proposals by survey: Cutting the tree and rolling processed motor oil to the trunk, collecting the roots from the soil after plowing the field, leaving an ant species (red ant) to the tree and let them kill the tree, pouring bleach or boiling water on the roots.

Petition to the European Parlament

In the Comenius project work “Invasive alien species- diversification or diminishing nature variety”, the students from Poland, Italy, Spain, Turkey, and Estonia analyzed the impact of invasive species on the local ecosystems . The measures of limiting the number of invasive species were examined, and it was concluded that invasive alien species impose a considerable harm on nature biodiversity, and dramatically diminish the number of local species. In working on the project the actuality of the issue on a global scale became apparent. We are turning to the European Parliament with a petition to consider and support our joint suggestions in the European legislation. We, the undersigned students from Poland, Spain, Italy, Turkey, and Estonia respectfully petition the European Parliament to consider and support our joint suggestions in the EU law on the subject of invasive species. Our suggestions are as follows: 1. Raising awareness of the issue of invasive species on all educational levels (kindergarten, elementary school, middle school, high school) according to age through various activities (games, projects, student research papers, international projects, etc). 2. Raising awareness of the problem of invasive species by informing and spreading information in communities via various means such as booklets, study

films,

conferences,

workshops,

exhibitions,

etc.

3. Engaging the media and press, social networking, etc (TV and radio shows, newspaper articles, etc) into prevention activities against the distribution of invasive species. 4. Involving universities, research groups, environmental education centers in activity of raising awareness of harmful effect of invasive species on local biodiversity, and taking respective preventive measures to address the problem.

5. Working out and implementing laws on a national and international scale. Effectuation compliance with the EU law regarding invasive species. Creating reserves for already distributed invasive species with a view to limit or keep their number under strict control, e.g. pet animals.

6. Introducing and observing annually The International Invasive Species Day to acknowledge the seriousness of the problem worldwide. We suggest the day be 15th of April.
