List Of Invasive Alien Species Of Union Concern
In 2016, following the EU Regulation 1143/2014 on Invasive Alien Species (IAS), the European Commission published a first list of 37 IAS of Union concern. The list was first updated in 2017 and comprised 49 species. Since the second update in 2019, 66 species are listed as IAS of EU concern. The species on the list are subject to restrictions on keeping, importing, selling, breeding and growing. Member States of the European Union must take measures to stop their spread, implement monitoring and preferably eradicate these species. Even if they are already widespread in the country they are expected to manage the species to avoid further spread. __TOC__ Sortable table of invasive alien species of Union concern ResourcesEU brochure on the 2017 list update with 49 species(pdf format)JRC report on the baseline distribution of the 37 species on the first list See also *List of invasive species in Europe This is a list of invasive species in Europe.

Marmorkrebs Procambarus Fallax Forma Virginalis
The marbled crayfish or (''Procambarus virginalis'') is a parthenogenetic crayfish that was discovered in the pet trade in Germany in 1995. Marbled crayfish are closely related to the "slough crayfish", ''Procambarus fallax'', which is widely distributed across Florida. No natural populations of marbled crayfish are known. Information provided by one of the original pet traders as to where the marbled crayfish originated was deemed "totally confusing and unreliable". The informal name ''Marmorkrebs'' is German for "marbled crayfish". Model organism Marbled crayfish are the only known decapod crustaceans to reproduce only by parthenogenesis. All individuals are female, and the offspring are genetically identical to the parent. Marbled crayfish are triploid animals with 276 chromosomes, which may be the main reason for their parthenogenetic reproduction. It is hypothesized that marbled crayfish originated from an error in meiosis resulting in a diploid gamete, which was t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baccharis Halimifolia
''Baccharis halimifolia'' is a North American species of shrubs in the family Asteraceae. It is native to Nova Scotia, the eastern and southern United States (from Massachusetts south to Florida and west to Texas and Oklahoma), eastern Mexico (Nuevo León, San Luis Potosí, Tamaulipas, Veracruz, Quintana Roo), the Bahamas, and Cuba. Widely used common names include eastern baccharis, groundsel bush, sea myrtle, and saltbush, with consumption weed, cotton-seed tree, groundsel tree, menguilié, and silverling also used more locally. In most of its range, where no other species of the genus occur, this plant is often simply called baccharis. Classification ''Baccharis halimifola'' was first described and named by Carl Linnaeus in his ''Species Plantarum'', published in 1753. No subspecies or varieties are recognized within the species. This species is the northernmost member of the large Western Hemisphere genus Baccharis in the aster family (Asteraceae). ''Senecio arborescens ...

Heracleum Persicum
''Heracleum persicum'', commonly known as Persian hogweed or by its native name ''Golpar'' ( fa, گلپر) is a species of Heracleum (plant), hogweed, a perennial herbaceous plant in the carrot family Apiaceae. It grows wild in humid mountainous regions in Iran and some adjacent areas. Having been introduced in the 1830s, it has spread across Scandinavia. It is now very common in northern Norway, where one of its names is Tromsø palm. The plant has also been spotted in Sweden. In Finland, it has been declared as invasive species. Persian hogweed is a polycarpic perennial, that is, a mature plant flowers and bears fruit season after season. Invasiveness status In Europe, Persian hogweed is included since 2016 in the list of Invasive Alien Species of Union concern (the Union list). This implies that this species cannot be imported, cultivated, transported, commercialized, planted, or intentionally released into the environment in the whole of the European Union. Uses Food u ...

Heracleum Mantegazzianum
''Heracleum mantegazzianum'', commonly known as giant hogweed, is a monocarpic perennial herbaceous plant in the carrot family Apiaceae. ''H. mantegazzianum'' is also known as cartwheel-flower, giant cow parsley, giant cow parsnip, or hogsbane. In New Zealand, it is also sometimes called wild parsnip (not to be confused with ''Pastinaca sativa'') or wild rhubarb. Giant hogweed is native to the western Caucasus region of Eurasia. It was introduced to Britain as an ornamental plant in the 19th century, and has also spread to other areas in Western Europe, the United States, and Canada. Its close relatives, Sosnowsky's hogweed and Persian hogweed, have similarly spread to other parts of Europe. The sap of giant hogweed is phototoxic and causes phytophotodermatitis in humans, resulting in blisters and scars. These serious reactions are due to the furanocoumarin derivatives in the leaves, roots, stems, flowers, and seeds of the plant. Consequently, it is considered to be a ...

Gunnera Tinctoria
''Gunnera tinctoria'', known as giant rhubarb or Chilean rhubarb, is a flowering plant species native to southern Chile and neighbouring zones in Argentina. It is unrelated to rhubarb, as the two plants belong into different orders, but looks similar from a distance and has similar culinary uses. It is a large-leaved perennial plant that grows to more than two metres tall. It has been introduced to many parts of the world as an ornamental plant and in some countries (for instance New Zealand, Great Britain and Ireland) it has spread from gardens and is becoming a weed problem. It is known under the synonyms: ''Gunnera chilensis'' Lam. and ''Gunnera scabra'' Ruiz & Pav. Taxonomy It was first described in 1782 by Juan Ignacio Molina as ''Panke tinctoria'', and was transferred to the genus, ''Gunnera'', in 1805 by Charles-François Brisseau de Mirbel.

Eriocheir Sinensis
The Chinese mitten crab ('; , "big sluice crab"), also known as the Shanghai hairy crab (, p ''Shànghǎi máoxiè''), is a medium-sized burrowing crab that is named for its furry claws, which resemble mittens. It is native to rivers, estuaries and other coastal habitats of East Asia from Korea in the north to Fujian, China in the south. It has also been introduced to Europe and North America, where it is considered an invasive species. The species features on the list of invasive alien species of Union concern. This means that import of the species and trade in the species is forbidden in the whole of the European Union.

Cortaderia Jubata
''Cortaderia jubata'' is a species of grass known by several common names, including purple pampas grass and Andean pampas grass. It is similar to its more widespread relative, the pampas grass ''Cortaderia selloana'', but it can get quite a bit taller, approaching seven meters in height at maximum. This grass is native to the northern Andes but it is well-known elsewhere as an invasive species noxious weed. This grass has only pistillate parts, that is, all individuals are female. It reproduces by apomixis, in which embryos develop without fertilization. Description This pampas grass, ''Cortaderia jubata'', has long, thin, razor-edged leaves forming a large bunch grass tussock from which the eye-catching inflorescences arise. At the top of a stem several meters in height is an inflorescence of plumelike spikelets. These panicles are pink or purplish when new and they gradually turn cream or white.
