Forested area tree litter deadwood mosaic

Dense tree cover builds forested microbial habitats by creating leaf-canopy, fine-root, litter, and deadwood compartments. Canopy surfaces host phyllosphere communities, roots transfer recent plant carbon to mycorrhizal fungi and rhizosphere bacteria, and lignocellulose from litterfall and deadwood selects decomposer fungi and bacteria that recycle carbon, nitrogen, and phosphorus in forest soils.
