Recently published research in Science magazine warns that older, taller trees are quickly becoming a thing of the past, consequently leaving forests in disarray. Forest dynamics being disrupted like this spells trouble for ecosystem equilibrium and biodiversity. While natural disturbances — flooding, landslides, insect infestations, fungi, vine overgrowth, disease, wildfire and even wind damage — negatively impact forests, they do not compare with the magnitude of harm humans have precipitated.
