When we think of an evergreen forest, we may immediately visualize tall trees with green foliage that last throughout the year. However, there are multiple ways of referring to these types of forests. In some contexts, they may be called coniferous forests, indicating the prevalence of cone-bearing trees such as spruce, pine, or fir. Alternatively, they might be labeled as boreal forests, focusing on their occurrence in cooler regions of the world, such as Canada, Siberia, or Scandinavia. Another term that can be used is taiga, the Russian word that describes the vast land of evergreens that stretches across northern Europe, Asia, and North America. Whatever the name, these forests play a critical role in preserving biodiversity and combating climate change.
