Detailed explanation-1: -coniferous forest, vegetation composed primarily of cone-bearing needle-leaved or scale-leaved evergreen trees, found in areas that have long winters and moderate to high annual precipitation. The northern Eurasian coniferous forest is called the taiga or the boreal forest.

Detailed explanation-2: -The taiga is characterized predominantly by a limited number of conifer species-i.e., pine (Pinus), spruce (Picea), larch (Larix), fir (Abies)-and to a lesser degree by some deciduous genera such as birch (Betula) and poplar (Populus). These trees reach the highest latitudes of any trees on Earth.

Detailed explanation-3: -Taigas are thick forests. Coniferous trees, such as spruce, pine, and fir, are common. Coniferous trees have needles instead of broad leaves, and their seeds grow inside protective, woody cones.

Detailed explanation-4: -What is a coniferous forest? A coniferous forest contains evergreen trees that bear cones. Elegant pines grow in this biome, along with spruce, fir, and tamarack. In much of the northern forest, the conifers mingle with deciduous trees, particularly aspen, birch, sugar maple, and basswood.

Detailed explanation-5: -Coniferous forests consist mostly of conifers, which are trees that grow needles instead of leaves and cones instead of flowers. Conifers tend to be evergreen-they bear needles all year long.
