In redwood forests, trees shed their leaves allowing decomposers to create a rich dark layer of soil on the surface. Nutrients from their leaves and other plant litter that would otherwise be unavailable are recycled back into the soil. This topsoil also acts as a shield, protecting redwood’s shallow roots from being trampled.
