taiga

This term describes the vast, subarctic belt of coniferous forests that characterizes the high northern latitudes. It evokes an image of dense, evergreen needles, acidic soil, and harsh, cold climates where deciduous trees struggle to survive. As a mass noun referring to a specific global biome, it is typically used without a plural form when discussing the ecological region as a whole. While it can technically be used countably in specific scientific contexts to describe different sections of the forest, it is almost always treated as an uncountable entity in general usage.
