Alaska's boreal forests are dominated by spruce trees, particularly white spruce and black spruce.

The boreal forests of Alaska, also known as the taiga, are characterized by cold temperatures and short growing seasons. Spruce trees thrive in these conditions, making them the primary species in the region's forests. These forests play an important role in carbon storage, wildlife habitat, and the timber industry. The dominance of spruce is a key feature of the landscape, alongside other coniferous trees like fir and pine.
