sphagnum is a type of moss that typically grows in wet, acidic environments, such as bogs and wetlands. It plays a crucial role in the ecosystem by helping to retain water and create habitats for various plants and animals. Sphagnum can absorb large amounts of water, making it essential for maintaining moisture in its surroundings. This moss is also significant for its ability to store carbon, which helps mitigate climate change. When sphagnum decomposes slowly in waterlogged conditions, it forms peat, a valuable resource used in gardening and horticulture. Peatlands, where sphagnum thrives, are important for biodiversity and carbon storage.
