Boreal kingdom

The Boreal kingdom, also known as the Holarctic kingdom, encompasses Eurasia and North America. This region is characterized by coniferous forests, often referred to as the taiga, which are dominated by evergreen trees like pines, spruces, firs, and larches. These forests are found in areas with long winters and moderate to high precipitation, and they often feature numerous lakes, bogs, and rivers. The soils in these regions are typically acidic and known as podzols.1

The Boreal kingdom is divided into several regions, including the Arctic and subarctic region, which is characterized by tundra and has a limited diversity of flowering plants but a greater diversity of cryptogams. Another region is the Eurosiberian region, which extends across Europe and Siberia and is dominated by conifers, giving way to deciduous forests to the south and tundra to the north. The climate in these areas is generally cold, with long winters and short growing seasons.234
