Drunken trees are not a completely new phenomenon—dendrochronological evidence can date thermokarst tilting back to at least the 19th century. [13] The southern extent of the subarctic permafrost reached a peak during the Little Ice Age of the 16th and 17th centuries, [24] and has been in decline since then.
Some berries can grow in both the taiga and the lower arctic (southern regions) tundra, such as bilberry, bunchberry and lingonberry. Taiga spruce forest in the Kenai National Wildlife Refuge, Alaska. Trees in this environment tend to grow closer to the trunk and not "bush out" in the normal manner of spruce trees.
This is a list of areas of existing old-growth forest which include at least 10 acres (4.0 hectares) of old growth. Ecoregion information from "Terrestrial Ecoregions of the World". [1] (NB: The terms "old growth" and "virgin" may have various definitions and meanings throughout the world. See old-growth forest for more information.)
Spruce is the standard material used in soundboards for many musical instruments, including guitars, mandolins, cellos, violins, and the soundboard at the heart of a piano and the harp. Wood used for this purpose is referred to as tonewood. Spruce, along with cedar, is often used for the soundboard/top of an acoustic guitar. The main types of ...
White spruce, black spruce and tamarack are most prevalent in the four northern eco-zones of the Taiga and Hudson Plains, while spruce, balsam fir, jack pine, white birch and trembling aspen are most common in the lower boreal regions. Large populations of trembling aspen and willow are found in the southernmost parts of the Boreal Plains. [12]
Old-growth forests are unique, usually having multiple horizontal layers of vegetation representing a variety of tree species, age classes, and sizes, as well as "pit and mound" soil shape with well-established fungal nets. [19] As old-growth forest is structurally diverse, it provides higher-diversity habitat than forests in other stages.

The taiga forests are mainly white spruce (Picea glauca), alaskan birch (Betula neoalaskana), balsam poplar (Populus balsamifera), and quaking aspen (Populus tremuloides) in the warmer drier areas, and black spruce (Picea mariana), and american larch (Larix laricina) where it is marshier but the ecoregion also contains scrubby areas of dwarf birch (Betula nana) and riverbanks of willows ...
