How do larch trees differ from most other taiga conifers?

While the taiga is primarily defined by evergreen conifers that retain their foliage year-round, larch trees (genus Larix) are a notable exception.

Unlike most other taiga conifers, which keep their needles throughout the winter, larch trees are deciduous. This means they shed their needlelike leaves every autumn, similar to broad-leaved deciduous trees. While they share the characteristic pyramidal growth habit of other conifers, this seasonal loss of foliage distinguishes them from the evergreen species—such as spruce, pine, and fir—that dominate the boreal forest landscape.12
