Boreal Forest is a biome from Zoo Tycoon 2.
- The boreal forest biome, which consists of a great band of evergreen conifer forests, extends around the Northern Hemisphere in the subarctic latitudes. Within this zone, the growing season is brief and the winter is long and cold. These circumstances exclude most broadleaf deciduous trees, which require more time to regrow their leaves than the subarctic climate provides. Evergreen trees, on the other hand, are ready to resume photosynthesis whenever the air grows mild enough. Furthermore, the compact, cylindrical shape and waxy skin of the needlelike leaves retard moisture loss during the winter, when environmental water is unavailable because it is frozen.
- Compared with the forests of lower latitudes, the boreal forests - often called by their Russian name of taiga - are rather uniform in structure and species composition. Trees, often in dense stands of even age, dominate. Many assume a narrow, pointed habit that permits snow to be shed readily. Ground vegetation within the shady forest is sparse, comprising low shrubs, many of them in the heath family, and a layer of mosses. Another conspicuous feature of the taiga region, from which the ice sheets retreated only about 10,000 years ago, is the countless ponds and bogs that pock the flat and poorly drained terrain.
- In Eurasia, the taiga spans the continent from the Russian Far East to Scandinavia. The westernmost forests are very monotonous, but the number of species rises as one moves to the east, and the forests of Hokkaido in northern Japan are comparatively diverse. An exception to the evergreen character of most of the taiga is the deciduous larch forests of eastern Siberia, where the bitterly cold winters of the continental interior make the retention of any leaves, even needles, a liability.
- The boreal forests of North America are richer in species than their Eurasian counterparts but are in other ways similar. Because of the north-south alignment of North American mountain ranges, taigalike conifer forests extend far into the temperate zone along the spines of the Cascade Range and Sierra Nevada, the Rocky Mountains, and the Appalachians.
