The primary type of tree found in a forest varies by the specific type of forest, but in many temperate and boreal forests, the dominant trees are coniferous species, such as pine, spruce, and fir. These trees are well adapted to varying climates and soil types. In contrast, tropical rainforests are predominantly composed of broadleaf evergreen trees, like mahogany and rubber trees. Each type of forest ecosystem supports a distinct biodiversity with a range of flora and fauna. The presence of these trees plays a key role in carbon sequestration, habitat creation, and affecting local climates.
