Conifers tend to be evergreen—they bear needles all year long. This makes the area climate more humid. One type of coniferous forest, the northern boreal forest, is found in 50° to 60°N latitudes.
Another type, temperate coniferous forests, grows in lower latitudes of North America, Europe, and Asia, in the high elevations of mountains.Coniferous forests consist mostly of conifers, which are trees that grow needles instead of leaves and cones instead of flowers. In some, needleleaf trees dominate, while others are home primarily to broadleaf evergreen trees or a mix of both tree types.
