Coniferous trees are a type of tree that produce cones and have needle-like leaves. They are often evergreen, meaning they retain their leaves throughout the year. Common examples of coniferous trees include pine, spruce, and fir. These trees are typically found in colder climates and are well-adapted to survive harsh weather conditions. Coniferous forests, also known as taiga or boreal forests, cover large areas in the northern hemisphere. These forests play a crucial role in the ecosystem by providing habitat for various wildlife and helping to regulate the Earth's climate. The wood from coniferous trees is widely used in construction and paper production.
