A coniferous forest is a forest consisting primarily of conifers. Conifers are trees that hold their leaves (needles) over the winter. Examples include Pine and Giant Redwoods.
This is contrasted with a deciduous forest, consisting of deciduous trees; or trees that loose their leaves in the fall. Examples of this include Maple, Beech, Elm, Oak.

Coniferous forests are made up mainly of cone-bearing or coniferous trees, such as spruces, hemlocks, pines and firs. The leaves of these trees are either small and needle-like or scale-like and most stay green all year around (evergreen). All are softwoods able to survive cold termperatures and acidic soil.
Coniferous forests are found mainly in the northern hemisphere, although some are found in the southern hemisphere.
The northern coniferous forests are called taiga or boreal forests. They cover vast areas of North America from the Pacific to the Atlantic, and range across northern Europe, Scandinavia, Russia and across Asia through Siberia and Mongolia to northern China and northern Japan.
Short summers and long winters
Coniferous trees thrive where summers are short and cool and winters long and harsh, with heavy snowfall that can last as long as 6 months. The needle-like leaves have a waxy outer coat which prevents water loss in freezing weather and the branches are soft and flexible and usually point downwards, so that snow slides off them. Larches are one example of a coniferous tree found in some of the coldest regions. Unusually for coniferous trees they are deciduous, that is they shed their leaves in winter.
Coniferous trees such as cypresses, cedars and redwoods are found in warmer regions.
Life on the forest floor
Even evergreen trees eventually shed their leaves and grow new ones. The needles fall to the forest floor and form a thick springy mat. Thread-like fungi help to break down or decompose the fallen needles. These fungi provide nutrients from the decomposed needles back to the roots of the trees. But because pine needles do not decompose easily, the soils are poor and acid.
These forests grow under widely differing conditions of climate and soil - from the tropics to the subarctic, and from heavy clays to poor sands. However, coniferous trees are especially conditioned to the winter climate. The trees of the taiga grow at the highest latitude of any forest. The most common are spruce, pine and firs.
Reach for the sky!
Cypresses, cedars and redwoods grow upright; the tallest of them can reach 20m in height. The trees are usually pyramid-shaped. Short, lateral branches grow quite close together but they are so flexible that the snow simply slides off. The leaves are small, hard and evergreen.
Little light penetrates the thick canopy of trees to reach the forest floor. Because of this gloom, only ferns and a few herbaceous plants grow here. Mosses, liverworts and lichens are also found on the forest floor and grow on tree trunks and branches. There are few flowering plants.

-Coniferous Forests are Boreal Forests, meaning cone-bearing.
-Confierous Forests cover about 11% of the Earth's land surface and have plants that reduce water loss by evolving a thin, needle-like evergreen leaves with a thick waxy coating and they can survive harsh winters or extended droughts and accomplish photosynthesis even under poor conditions.
-They have longer growing seasons and cold and severe winters
-There are deciduous trees like aspen and birch, but coniferous trees dominate because they are drought resistant and winter tough.
-They have numerous ponds and lakes because of a glacial carved surface

It's a forest made up of coniferous trees. The three types of coniferous trees (which produce CONES for their fruit) are: pine, fir and spruce.

Conifers are trees that produce needles instead of broad leaves. Pine and spruce are types of coniferous trees.
