Plant litter

From Wikipedia, the free encyclopedia

Plant litter (sometimes called leaf litter or tree litter) is dead plant material, such as leaves, bark, and twigs, that has fallen to the ground. Litter provides habitat for small animals, fungi, and plants, and the material may be used to construct nests. As litter decomposes, nutrients are released to the environment. The portion of the litter that is not readily decomposable is known as humus. One can find lots of bugs and insects in the leaf litter.
