What is dominated by coniferous trees such as spruce?

Areas dominated by coniferous trees, such as spruce, are typically found in boreal forests, also known as taiga. These forests are characterized by cold climates and are primarily located in northern regions, including Canada, Scandinavia, and parts of Russia. The dominance of conifers in these ecosystems is due to their ability to withstand harsh winters and their adaptation to nutrient-poor soils. Additionally, spruce trees play a crucial role in the local biodiversity and provide habitat for various wildlife species.
