tundra
含义: A vast, flat, treeless Arctic region where the subsoil is permanently frozen and vegetation is limited to mosses, lichens, and low-growing shrubs.
The tundra biome covers parts of northern Canada, Alaska, Scandinavia, and Siberia. It is characterised by extreme cold, short growing seasons, and permafrost, which prevents trees from establishing deep root systems. Despite its harsh conditions, the tundra supports wildlife including caribou, Arctic foxes, and migratory birds. Alpine tundra occurs at high altitudes above the tree line in mountain ranges worldwide. Climate change is warming tundra regions faster than the global average.
