Natura 2000
Natura 2000 is a network of nature protection areas in the territory of the European Union. It is made up of Special Areas of Conservation and Special Protection Areas designated under the Habitats Directive and the Birds Directive, respectively. The network includes both terrestrial and Marine Protected Areas. The Natura 2000 network covered more than 18% of the European Union's land area and more than 7% of its marine area in 2022. History In May 1992, the governments of the European Communities adopted legislation designed to protect the most seriously threatened habitats and species across Europe. The Habitats Directive complements the Birds Directive adopted in 1979, and together they make up the Natura 2000 network of protected areas. The Birds Directive requires the establishment of Special Protection Areas for birds. The Habitats Directive similarly requires Sites of Community Importance which upon the agreement of the European Commission become Special Areas o ...

Freshwater Pearl Mussel
The freshwater pearl mussel (''Margaritifera margaritifera'') is an endangered species of freshwater mussel, an Aquatic animal, aquatic bivalve mollusc in the family Margaritiferidae. Although the name "freshwater pearl mussel" is often used for this species, other freshwater mussel species (e.g. ''Margaritifera auricularia'') can also create freshwater pearls, pearls and some can also be used as a source of mother of pearl. Most cultured pearls today come from ''Hyriopsis'' species in Asia, or ''Amblema'' species in North America, both members of the related family Unionidae; pearls are also found within species in the genus unio (genus), ''Unio''. The interior of the shell of ''Margaritifera margaritifera'' has thick nacre (the inner mother of pearl layer of the shell). This species is capable of making fine-quality pearls, and was historically exploited in the search for pearls from wild sources. In recent times, the Russian malacologist Valeriy Zyuganov received worldwide re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marsh Fritillary
The marsh fritillary (''Euphydryas aurinia'') is a butterfly of the family Nymphalidae. Commonly distributed in the Palearctic region, the marsh fritillary's common name derives from one of its several habitats, marshland. The prolonged larval stage lasts for approximately seven to eight months and includes a period of hibernation over the winter. The larvae are dependent on the host food plant '' Succisa pratensis'' not only for feeding but also for hibernation, because silken webs are formed on the host plant as the gregarious larvae enter hibernation. Females lay eggs in batches on the host plant and are, like other batch-layers, selective about the location of oviposition because offspring survivorship levels for batch-layers are more tied to location selection than they are for single-egg layers. As of 2019 the butterfly's global conservation status is considered of least concern, but it has faced rapid decline and is considered regionally vulnerable or endangered over much o ...

Coenagrion Mercuriale
''Coenagrion mercuriale'', the southern damselfly, is a species of damselfly in the family Coenagrionidae. It is found in Algeria, Austria, Belgium, France, Germany, Italy, Liechtenstein, Luxembourg, Morocco, the Netherlands, Portugal, Romania, Slovakia, Slovenia, Spain, Switzerland, Tunisia, and the United Kingdom. Its natural habitats are rivers and freshwater springs. It is threatened by habitat loss. The specific part of the scientific name, ''mercuriale'', is because of the distinctive markings on the second segment of the abdomen that resembles the astrological symbol for the planet Mercury - ☿. This also gives the species an alternative common name of mercury bluet. Habitat They require areas of open vegetation, mixed with slow flowing water in which to lay their eggs. The larvae spend 2 years underwater before emerging as damselflies. Status in the United Kingdom It is thought that 25% of the world population exists within the United Kingdom but it has declined ...

Austropotamobius Pallipes
''Austropotamobius pallipes'' is an endangered European freshwater crayfish, and the only crayfish native to the British Isles. Its common names include white-clawed crayfish and Atlantic stream crayfish. Distribution It is found from the easterly Balkan Peninsula to Spain and reaches its northerly limit in Great Britain, as well as Ireland (where it is considered introduced), where it is limited to some regions only: its highest densities are in chalk streams. ''A. pallipes'' is the only crayfish found in Ireland, occurring over limestone areas in rivers, streams, canals, and lakes. In France, ''A. pallipes'' is found in streams such as the Mornante and Sellon, two small tributaries of the Dorlay in the Loire department. It is protected as a heritage species. It has also been introduced to Corsica, Liechtenstein, and Portugal (from where it is now extirpated). It was once found across most of Great Britain; however its distribution is rapidly shrinking, and it is recorded in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brook Lamprey
The brook lamprey (''Lampetra planeri''), also known as the European brook lamprey and the western brook lamprey is a small European lamprey species that exclusively inhabits freshwater environments. The species is related to, but distinct from, the North American western brook lamprey ('' Lampetra richardsoni''). Description The brook lamprey is a common, non-parasitic species that is endemic to Europe. Adult brook lampreys measure from . The body is highly elongated and dark blue or greenish above, lightening to yellowish off-white on the sides and pure white on the ventral side. Like all lampreys, these fish lack paired fins and possess a circular sucking disc instead of jaws, which is filled with blunt teeth. They have a single nostril and seven small gill openings on either side behind the eye. The brook lamprey can be told from the closely related river lamprey (''Lampetra fluviatilis'') by the fact that its two dorsal fins are more closely linked together. Distributi ...

Cottus Perifretum
''Cottus perifretum'', the bullhead or miller's thumb, is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. It is found on both sides of the English Channel, native to Great Britain. It also inhabits Atlantic drainages from the Garonne River (tributaries draining from Massif Central) to the Scheldt in France and Belgium, and the Moselle and Sieg in Germany. It is considered invasive in the Rhine drainage in Germany and the Netherlands. This invasive population in the Rhine is an intermediate between this species and '' Cottus rhenanus''. Although this species is native to England and Wales it is considered to be a non-native invasive species in Scotland. This species was described as a separate species from the European bullhead (''C. gobio'') in 2005 by Jörg Freyhof, Maurice Kottelat and Arne W. Nolte. The specific name ''perifretum'' is a combination of ''peri'', meaning "around", and ''fretum'', meaning "straits", an allusion to t ...

European Bullhead
The European bullhead (''Cottus gobio'') is a freshwater fish that is widely distributed in Europe, mainly in rivers. It is a member of the family Cottidae, a type of sculpin. It is also known as the miller's thumb, freshwater sculpin, common bullhead, and cob. The European bullhead is a small demersal fish that lives both in cold, clear, fast-flowing small streams and in middle-sized rivers. It also occurs on gravelly shores of cold lakes. Further, it thrives in diluted brackish water of the Northern Baltic Sea. Description The bullhead has a large broad head and tapering body, large fins and a rounded tail. The eyes are located near the top of the head. To the distinction from the other freshwater sculpin species found in Northern Europe, it can be told from the alpine bullhead ''Cottus poecilopus'' by the fact that the rays of its pelvic fins are of similar lengths while the first and last rays are longer in the alpine bullhead. It can be distinguished from the fourhorn sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Otter
The Eurasian otter (''Lutra lutra''), also known as the European otter, Eurasian river otter, European river otter, common otter, and Old World otter, is a semiaquatic mammal native to Eurasia and the Maghreb. The most widely distributed member of the otter subfamily (Lutrinae) of the Mustelidae, weasel family (Mustelidae), it is found in the waterways and coasts of Europe, many parts of Asia, and parts of northern Africa. The Eurasian otter has a diet mainly of fish, and is strongly territorial. It is endangered in some parts of its range, but is recovering in others. Description The Eurasian otter is a typical species of the otter subfamily. Brown above and cream below, these long, slender creatures are well-equipped for their aquatic habits. Their bones show osteosclerosis, increasing their density to reduce buoyancy. This otter differs from the North American river otter by its shorter neck, broader visage, the greater space between the ears and its longer tail. However, the ...

Northern Crested Newt
The northern crested newt, great crested newt or warty newt (''Triturus cristatus'') is a newt species native to Great Britain, northern and central continental Europe and parts of Western Siberia. It is a large newt, with females growing up to long. Its back and sides are dark brown, while the belly is yellow to orange with dark blotches. Males develop a conspicuous jagged crest on their back and tail during the breeding season. The northern crested newt spends most of the year on land, mainly in forested areas in lowlands. It moves to aquatic breeding sites, mainly larger fish-free ponds, in spring. Males court females with a ritualised courtship display, display and deposit a spermatophore on the ground, which the female then picks up with her cloaca. After fertilisation, a female lays around 200 eggs, folding them into water plants. The larvae develop over two to four months before metamorphosis, metamorphosing into terrestrial juveniles (efts). Both larvae and land-dwellin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitats Directive
The Habitats Directive (more formally known as Council Directive 92/43/EEC on the Conservation of natural habitats and of wild fauna and flora) is a directive adopted by the European Community in 1992 as a response to the Berne Convention. The European Community was reformed as the European Union the following year, but the directive is still recognised. The Habitats Directive required national governments to specify areas that are expected to be ensuring the conservation of flora and fauna species. This led to the setting up of a network of protected areas across the EU, along with 'Special Areas of Conservation', which together with the existing Special Protection Areas, became the so-called Natura 2000 network established to protect species and habitats. This directive is one of the main pillars of the European Union's system of wildlife and nature conservation, another being the Birds Directive. The Habitats Directive, together with the Birds Directive, are also called the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
