Coniferous trees

Coniferous trees are cone-bearing woody plants in the gymnosperm group Coniferales (or Pinales), typically characterized by needle-like or scale-like leaves and, in many species, evergreen foliage.

Coniferous trees are cone-bearing woody plants in the gymnosperm group Coniferales (or Pinales), typically characterized by needle-like or scale-like leaves and, in many species, evergreen foliage. They include pines, spruces, firs, cedars, cypresses, junipers, and related groups, and are important components of boreal and temperate forests worldwide.

Classification and traits

Coniferous trees belong to the gymnosperms and are usually placed in the order Pinales or Coniferales. They are woody plants with cones and typically narrow leaves adapted to reduce water loss.

Diversity and examples

The group includes more than 550 living species, and Canadian sources commonly cite about 600 worldwide. Well-known genera include Pinus, Picea, Abies, Juniperus, Cupressus, Tsuga, and Larix.

Distribution and habitat

Conifers are most abundant in cool temperate and boreal regions, although they also occur in warmer mountain habitats and across most of the world except Antarctica. Coniferous forests are common where winters are long and precipitation is moderate to high.

Uses and ecological importance

Coniferous trees provide timber, paper pulp, resin, oils, and ornamental value. They also form major forest ecosystems and include some of the oldest and tallest trees on Earth.
