Flora Of Finland
The wildlife of Finland is affected by prevailing environmental conditions. The phytogeography of Finland is shared between the Arctic, central European, and northern European provinces of the Circumboreal Region within the Boreal Kingdom. The territory of Finland can be subdivided into three ecoregions: the Scandinavian and Russian taiga, Sarmatic mixed forests, and Scandinavian montane birch forest and grasslands. Taiga covers most of Finland from northern regions of southern provinces to the north of Lapland. On the southwestern coast, south of the Helsinki-Rauma, Finland, Rauma line, forests are mixed as is more typical in the Baltic region. In the extreme north of Finland, near the tree line and Arctic Ocean, montane birch forests are common. Habitat types The habitat types of Finland have been divided into eight groups by prevailing environmental conditions, and by the plant and animal species typical of such areas. The groups consist of habitat types of the Baltic Sea, i ...

Willow Warbler
The willow warbler (''Phylloscopus trochilus'') is a very common and widespread leaf warbler which breeds throughout northern and temperate Europe and the Palearctic, from Ireland east to the Anadyr River basin in eastern Siberia. It is strongly migratory, with almost all of the population wintering in sub-Saharan Africa. It is a bird of open woodlands with trees and ground cover for nesting, including most importantly birch, alder, and willow habitats. The nest is usually built in close contact with the ground, often in low vegetation. Like most Old World warblers (Sylviidae), this small passerine is insectivorous. In northern Europe, it is one of the first warblers to return in the spring, though later than the closely related chiffchaff. In spite of its small size, the willow warbler performs one of the longest migrations of any animal. Taxonomy The willow warbler was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''System ...

Thysanura
Thysanura is the now Deprecation, deprecated name of what was, for over a century, recognised as an Order (biology), order in the Class (biology), class Insecta. The two constituent groups within the former order, the Archaeognatha (jumping bristletails) and the Zygentoma (silverfish and firebrats), share several characteristics, such as of having three long caudal filaments, the lateral ones being the Cercus, cerci, while the one between (telson) is a Anatomical terms of location#Medial and lateral, medial cerciform appendage, specifically an epiproct. They are also both wingless, and have bodies covered with fine scales, rather like the scales of the practically unrelated Lepidoptera. In the late 20th century, it was recognized that the two suborders were not sister taxa, therefore Thysanura was paraphyletic, and the two suborders were each raised to the status of an independent monophyletic order, with Archaeognatha sister taxon to the Dicondylia, including the Zygentoma. Althou ...

European Polecat
The European polecat (''Mustela putorius''), also known as the common polecat, black polecat and forest polecat, is a mustelid species native to Europe, Western Asia and North Africa. It is of a generally dark brown colour, with a pale underbelly and a dark mask across the face. Occasionally, colour mutations including albinos, leucists, isabellinists, xanthochromists, amelanists, and erythrists occur. It has a shorter, more compact body than other '' Mustela'' species, a more powerfully built skull and dentition, is less agile, and is well known for having the characteristic ability to secrete a particularly foul-smelling liquid to mark its territory. It is much less territorial than other mustelids, with animals of the same sex frequently sharing home ranges. Like other mustelids, the European polecat is polygamous, with pregnancy occurring after mating, following induced ovulation. It usually gives birth in early summer to litters consisting of five to ten kits, which ...

Wolverine
The wolverine ( , ; ''Gulo gulo''), also called the carcajou or quickhatch (from East Cree, ''kwiihkwahaacheew''), is the largest land-dwelling species, member of the family Mustelidae. It is a muscular carnivore and a solitary animal. The wolverine has a reputation for ferocity and strength out of proportion to its size, with the documented ability to kill prey many times larger than itself. The wolverine is found primarily in remote reaches of the Northern Taiga, boreal forests and subarctic and alpine tundra of the Northern Hemisphere, with the greatest numbers in Northern Canada, the U.S. state of Alaska, the mainland Nordic countries of Europe, and throughout western Russia and Siberia. Its population has steadily declined since the 19th century owing to trapping, range reduction and habitat fragmentation. The wolverine is now essentially absent from the southern end of its range in both Europe and North America. Naming The wolverine's questionable reputation as an insa ...

Gray Wolf
The wolf (''Canis lupus''; : wolves), also known as the grey wolf or gray wolf, is a canine native to Eurasia and North America. More than thirty subspecies of ''Canis lupus'' have been recognized, including the dog and dingo, though grey wolves, as popularly understood, only comprise naturally-occurring wild subspecies. The wolf is the largest wild extant member of the family Canidae, and is further distinguished from other '' Canis'' species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller ''Canis'' species, such as the coyote and the golden jackal, to produce fertile hybrids with them. The wolf's fur is usually mottled white, brown, grey, and black, although subspecies in the arctic region may be nearly all white. Of all members of the genus ''Canis'', the wolf is most specialized for cooperative game hunting as demonstrated by its physical adaptations to tackling large p ...

Arctic Fox
The Arctic fox (''Vulpes lagopus''), also known as the white fox, polar fox, or snow fox, is a small species of fox native to the Arctic regions of the Northern Hemisphere and common throughout the Tundra#Arctic tundra, Arctic tundra biome. It is well adaptation, adapted to living in cold environments, and is best known for its thick, warm fur that is also used as camouflage. It has a large and very fluffy tail. In the wild, most individuals do not live past their first year but some exceptional ones survive up to 11 years. Its body length ranges from , with a generally rounded body shape to minimize the escape of body heat. The Arctic fox preys on many small creatures such as lemmings, voles, ringed seal pups, fish, waterfowl, and seabirds. It also eats carrion, berries, seaweed, and insects and other small invertebrates. Arctic foxes form Monogamy in animals, monogamous pairs during the breeding season and they stay together to raise their young in complex underground dens. ...

Nathusius' Pipistrelle
Nathusius' pipistrelle (''Pipistrellus nathusii'') is a small bat in the genus ''Pipistrellus''. It is very similar to the common pipistrelle and has been overlooked in many areas until recently but it is widely distributed across Europe. It was described by two German naturalists, Alexander Keyserling and Johann Heinrich Blasius, and named by them after Hermann von Nathusius, in gratitude for his support of their research. Description The length of the head and body is 46–55 mm and the wingspan is 220–250 mm. It has a forearm length of 32–40 mm and weighs about 6–15.5g. The fifth finger is longer than 43 mm. Its fur is medium-dark reddish-brown above, often with paler tips, and is pale brown below. The fur is longer and less uniformly colored compared to the common pipistrelle. It is also larger, with broader wings. The face, ears, wings, and tail are dark. Distribution Nathusius' pipistrelle occurs from Western Europe eastward as far as the Ural M ...

Conservation Status
The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status are in use at international, multi-country, national and local levels, as well as for consumer use such as sustainable seafood advisory lists and certification. The two international systems are by the International Union for Conservation of Nature (IUCN) and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). International systems IUCN Red List of Threatened Species The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conse ...

Natterer's Bat
Natterer's bat (''Myotis nattereri'') is a European Vespertilionidae, vespertilionid bat with pale wings. It has brown fur tending to greyish-white on its underside. It is found across most of the continent of Europe, parts of the Near East and North Africa. It feeds on insects and other invertebrates which it catches on the wing or pursues on the ground. In summer it roosts in deciduous and coniferous trees, buildings or bat boxes close to its feeding habitats. In winter it Hibernation, hibernates in caves, tunnels, mines or cellars, usually hiding in crevices. This bat was first described in 1817 by Heinrich Kuhl, who named it in honour of the Austrian naturalist Johann Natterer. Description Natterer's bat is a medium-sized species and grows to a head and body length of with a forearm (elbow to wrist) length of . It weighs between . The short, dense fur on the Dorsum (anatomy), dorsal (upper) surface of head and body is greyish-brown while the ventral (under) surface is whitish ...

Lake Saimaa
Saimaa ( , ; ) is a lake located in the Finnish Lakeland area in southeastern Finland. With a surface area of approximately , it is the largest lake in Finland, and the fourth-largest natural freshwater lake in Europe. The name Saimaa likely comes from a non-Uralic, non-Indo European substrate language. Alternatively, it has been proposed that the name may be connected to the Sami word ''sápmi''. History The lake was formed by glacial melting at the end of the Ice Age. Major towns on the lakeshore include Lappeenranta, Imatra, Savonlinna, Mikkeli, Varkaus, and Joensuu. About 6,000 years ago, ancient Lake Saimaa, estimated to cover nearly at the time, was abruptly discharged through a new outlet. The event created thousands of square kilometres of new residual wetlands. Following this event, the region saw a population maximum in the decades following only to later return to an ecological development towards old boreal conifer forests which saw a decline in population. To ...

Saimaa Ringed Seal
The Saimaa ringed seal (''Pusa hispida saimensis'', Finnish: ''saimaannorppa'') is a subspecies and glacial relict of ringed seal (''Pusa hispida''). They are among the most endangered seals in the world, having a total population of only about 500 individuals. The only existing population of these seals is found in Lake Saimaa, Finland (hence the name). They have lived in complete isolation from other ringed seal species for around 9,500 years and have diverged into a morphologically and ecologically different subspecies of ringed seal. The population is descended from ringed seals that were separated from the rest when the land rose after the last ice age. This seal, along with the Ladoga seal and the Baikal seal, is one of the few living freshwater seals. Distribution Habitat The Saimaa ringed seal is endemic to their habitat in Lake Saimaa, Finland. The lake lies between the cities of Lappeenranta in the south and Joensuu in the north, spanning an oval of approximat ...
