In a Natural Climate Solution geoengineered restored forest ecosystem, for example, growing trees store carbon in their trunks, branches and leaves. Leaves, twigs and branches that fall to the ground from the forest canopy enrich the forest soils with organic matter and help store vast quantities of carbon below ground. Because restored forests provide habitat for animals, animals living in the these forest ecosystems help sequester carbon by storing carbon in their bodies. Forest animals include insects, frogs, lizards, and mammals. In forest leaf litter and soils, animals including protists, nematodes, earthworms, insects, reptiles and mammals live within this soil ecosystem and sequester carbon as well. Over time, water runoff from forest ecosystems will enhance the waters of streams and rivers with forest components such as insects, leaves and dissolved organic carbon. These inputs will, in turn, provide food for aquatic plants and animals that also sequester carbon.
