The taiga biome is located in upper Canada, Alaska, Russia, and South America. It has biotic factors like black foxes, foxes, squirrels, and deer, and abiotic factors including wind, air, snow, and trees. Temperatures in the taiga range from -65°F to 70°F (-54°C to 21°C) in the winter and summer, respectively. Threats to the taiga include deforestation, pollution from vehicles and factories, which contribute to climate change concerns. Several species are endangered, such as lynx, wood bison, and Siberian tiger.
