Abstract
Leaf litter decomposition is an essential biological phenomenon that occurs within ecosystems, as it affects factors such as nutrient cycling, plant growth, soil fertility and other processes. Understanding the mechanisms that are attributed to leaf litter decomposition can help explain the role that leaf litter plays in ecosystems. A total of eight leaf litter bags were placed in environments of similar conditions on a green roof with the purpose of understanding how leaf size affects the rate of decomposition. The two species of variable size were coneflower (Echinacea tennesseensis, larger leaf) and baptisia (Baptisia australis, smaller leaf). The study found that decomposition occurred at faster rates for plants with a smaller leaf size compared to those that had larger leaf size. Quicker rates of leaf litter decomposition increases the efficiency of bioavailable nutrients to the ecosystem and improves carbon storage; it also furthers the fertility, protection, and nutrient cycling of soil. It is pertinent to understand this biological phenomena within the context of backyards, parks, greenroofs, and urban areas.
