- </span><span>Temperate deciduous forest: Trees are deciduous, leaves are lost annually. Canopy is moderately dense, so there is more light than in tropical rainforests.
- </span><span>Boreal forest: Trees are evergreen conifers with needle-like leaves. Canopy is thick and permits low light penetration.</span>
