Tree litter, also known as leaf litter, refers to the layer of decaying leaves, branches, and other organic debris that accumulates beneath trees. While tree litter has many benefits, such as providing habitat for small animals and serving as a natural fertilizer for plants, it can also create a mess in yards and walkways. Fortunately, there are a variety of synonyms for tree litter that can be used to describe this natural debris. Some alternatives include woodland detritus, forest litter, leaf detritus, woody debris, or simply, fallen leaves. No matter the term used, it is important to properly dispose of tree litter to maintain a clean and healthy environment.
