Taiga | Plants, Animals, Climate, Location, & Facts | Britannica
2024年10月28日 · The taiga biome consists of three roughly parallel zones: closed-canopy forest, lichen woodland or sparse taiga, and forest-tundra. The closed-canopy forest is the southernmost portion of the taiga. It contains the greatest richness of species, the warmest soils, the highest productivity, and the longest growing season within the boreal zone.
Taiga Biome – Boreal Forest - Science Notes and Projects
2024年5月29日 · Taiga soils are generally thin, nutrient-poor, and acidic due to slow decomposition rates and the accumulation of organic matter. A layer of permafrost often covers the soil. Annual precipitation in the taiga ranges from 30 to 85 centimeters (12 to 33 inches), with most of it falling as snow.
Taiga of North America - Wikipedia
The main type of soil in the taiga is Spodosol. These soils contain a Spodic horizon, a sandy layer of soil that has high accumulations of iron and aluminum oxides, which lays underneath a leached A horizon.
