Betula pubescens, commonly known as downy birch and also as moor birch, white birch, European white birch or hairy birch, is a species of deciduous tree, native and abundant throughout northern Europe and northern Asia, growing further north than any other broadleaf tree. It is closely related to, and often confused with, the silver birch, but grows in wetter places with heavier soils and poorer drainage; smaller trees can also be confused with the dwarf birch.
Eupsilia transversa, the satellite, is a moth of the family Noctuidae. The species was first described by Johann Siegfried Hufnagel in 1766. It is distributed throughout the Palearctic.
An Arctic–alpine taxon is one whose natural distribution includes the Arctic and more southerly mountain ranges, particularly the Alps. The presence of identical or similar taxa in both the tundra of the far north, and high mountain ranges much further south is testament to the similar environmental conditions found in the two locations. Arctic–alpine plants, for instance, must be adapted to the low temperatures, extremes of temperature, strong winds and short growing season; they are therefore typically low-growing and often form mats or cushions to reduce water loss through evapotranspiration.
Betula glandulosa, the American dwarf birch, also known as resin birch or shrub birch, is a species of birch native to North America.
Betula platyphylla, the Asian white birch or Japanese white birch, is a tree species in the family Betulaceae. It can be found in subarctic and temperate Asia in Japan, China, Korea, Mongolia, the Russian Far East, and Siberia. It can grow to be 30 metres tall.

Located in the Scandinavian Peninsula, Sweden is a mountainous country dominated by lakes and forests. Its habitats include mountain heath, montane forests, tundra, taiga, beech forests, rivers, lakes, bogs, brackish, marine coasts, and cultivated land. The climate of Sweden is mild for a country at this latitude, largely owing to the significant maritime influence.
The Canadian Low Arctic Tundra ecoregion covers a rolling landscape of shrubby tundra vegetation along the northern edge of the mainland Canada along the border of the Northwest Territories and Nunavut, and a small portion in Quebec on the northeast coast of Hudson Bay. The region is important for large herds of caribou and other large mammals, and for large nesting colonies of birds such as snow geese. The region is mostly intact, with 95% remaining intact.
