Conifers are classified as trees belonging to the division Pinophyta, which mainly includes species that produce cones and are often evergreen. Common examples of conifer trees are pines, firs, spruces, cedars, and redwoods. These trees typically have needle-like leaves that help reduce moisture loss in cold or dry climates. Conifers are significant in forestry and ecology as they provide timber, habitat for wildlife, and play a critical role in carbon sequestration. Additionally, many conifers are adapted to survive in various environmental conditions, making them widespread across different geographic regions.
