Jlenok [28]

In coniferous forests, the terrestrial biome receives precipitation of up to 300 to 900 millimeters (mm) each year.

Coniferous forests mainly consist of conifers and grow trees that produce thick needles and cones instead of growing flowers and leaves.

These are evergreen plants and stay green, healthy, and sustainable all year long.

In spite of flowers, these trees bear needles annually.

Moreover, conifers are very adaptive trees that can grow in very cold and dry climate zones.

It is due to their adaptability that they can survive all year long without losing a life.

Siberian fir, Dahurian, and Siberian larches are examples of confer forests.
