Blanket of reddish-brown ponderosa pine needles covering the ground.

Plant litter (sometimes called leaf litter, leaf mold 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. Image File history File linksMetadata Plant_litter. ... Image File history File linksMetadata Plant_litter. ...
