Moss

Mosses are typically found in moist environments although most species can withstand prolonged periods of desiccation. In terrestrial ecosystems, mosses are important in preventing soil erosion. Numerous species of moss are found in fresh water but there are no salt water species.

Mosses are particularly prominent in the tropics, however, they have a significant presence in the boreal forest, the woodlands of the temperate zones, and tundra regions. In the arctic tundra, mosses can constitute 50-90% of the ecosystem's biomass.
