Detailed explanation-1: -The taiga is the driest and coldest of the three and is sometimes called the boreal forest or the coniferous forest. It is the largest of all the land biomes. The taiga has several characteristics that distinguish it from the other forest biomes. First, it is covered with evergreen, or coniferous, trees.

Detailed explanation-2: -The boreal forest, also known as coniferous forest, is found roughly between 50o and 60o north latitude across most of Canada, Alaska, Russia, and northern Europe. Boreal forests in North America are sometimes referred to as Taiga.

Detailed explanation-3: -Boreal forests, or taiga, represent the largest terrestial biome. Occuring between 50 and 60 degrees north latitudes, boreal forests can be found in the broad belt of Eurasia and North America: two-thirds in Siberia with the rest in Scandinavia, Alaska, and Canada.

Detailed explanation-4: -The most common coniferous species found in the boreal forest include black and white spruce, balsam fir, jackpine, and tamarack. The most common deciduous trees found in the boreal forest include white birch, trembling aspen and balsam poplar.

Detailed explanation-5: -Spruce, fir, pine, and tamarack are the main species found in the Canadian boreal forest. Except for tamarack, which drops its needles every fall, they remain green all year. Broad-leaf deciduous trees, such as trembling aspen, balsam poplar, and birch, are also widely distributed across the boreal forest.
