Phytogeographically, Finland is shared between the Arctic, central European and northern European provinces of the Circumboreal Region within the Boreal Kingdom.
According to the WWF, 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 line, forests are characterized by mixed forests, that are more typical in the Baltic region.
In the extreme north of Finland, near the tree line and Arctic Ocean, Montane Birch forests are common.
Similarly, Finland has a diverse and extensive range of fauna.
There are at least sixty native mammalian species, 248 breeding bird species, over seventy fish species and eleven reptile and frog species present today, many migrating from neighboring countries thousands of years ago.
Large and widely recognized wildlife mammals found in Finland are the brown bear (the national animal), gray wolf, wolverine and elk.
Three of the more striking birds are the Whooper Swan, a large European swan and the national bird of Finland; the Capercaillie, a large, black-plumaged member of the grouse family; and the European Eagle-owl.
The latter is considered an indicator of old-growth forest connectivity, and has been declining because of landscape fragmentation.
The most common breeding birds are the Willow Warbler, Common Chaffinch and Redwing.
Of some seventy species of freshwater fish, the northern pike, perch and others are plentiful.
Atlantic salmon remains the favourite of fly rod enthusiasts.
The endangered Saimaa Ringed Seal, one of only three lake seal species in the world, exists only in the Saimaa lake system of southeastern Finland, down to only 300 seals today.
It has become the emblem of the Finnish Association for Nature Conservation.
This species can still be found throughout most of the Western Palearctic.
In most European countries there is at least a small population, except in Norway where it is not present.
The breeding range extends as far east as the Urals, whereas the most western population is that of Portugal.
Breeding also occurs in northern Africa, mostly in Morocco.
In Great Britain, the species is limited to southern England.
In Ireland the species is rarely seen, and mainly in the South, although there are a number of breeding records, the most recent from 1971.
Despite having a wide distribution, this bird is not common in many areas and has strong populations only in France, Spain, Russia, Belarus and Poland where the greater part of the European population can be found.
Breeding sites frequently change, with some sporadic nesting occurring outside known breeding areas, however clear signs of reduced range are apparent and are associated with population decline. 
Vilsandi National Park () is a national park in Saare County, Estonia.
It includes part of the island of Vilsandi, a number of smaller islands, adjacent parts of western Saaremaa and the Harilaid peninsula on Saaremaa, all in Kihelkonna Parish.
The park grew from a bird reserve founded in 1910.
It is a highly sensitive ecosystem due to the use of the area as stop-over by many migratory birds, like barnacle geese and Steller's Eider, and as a breeding and nesting ground for over 247 species of birds, of which the most common is the eider duck.
One third of all protected plant species in Estonia can also be found in the national park.
Hunting is absolutely prohibited.
This park is a popular tourist destination for both Estonians and foreign visitors, particularly from Finland. 
The breeding season is the most suitable season, usually with favourable conditions and abundant food and water, for breeding.
Abiotic factors such as the timing of seasonal rains and winds can also play an important role in breeding onset and success.
Many species breed in colonies or large communities which is known as communal breeding.
It is common to see large congregations of these species in particular favourable locations in their breeding seasons.
These breeding colonies and their location are generally protected by wildlife conservation laws to keep the species from going extinct.
Some species have evolved for communal breeding in large breeding colonies and can not breed in smaller numbers or pairs alone.
These species can be threatened by imminent extinction if they are hunted on their breeding grounds or if their breeding colonies are destroyed.
The Passenger pigeon is a famous example of probably the most numerous land bird on the American continent which had evolved for communal breeding that went extinct due to large scale hunting in its communal breeding grounds during the breeding season and its inability to breed in smaller numbers. 
The species can be found throughout Finland, Norway, Slovenia, Sweden, and in the UK.
