Clear-cut ground disappears within weeks under fast pioneer plants engineered for reproduction

Evidence

Forest ecosystems have tools for dealing with massive disturbance, evolved from a history of blowdown, landslide, and fire. The early successional plant species arrive immediately and get to work on damage control. These plants—known as opportunistic, or pioneer, species— have adaptations that allow them to thrive after disturbance. Because resources like light and space are plentiful, they grow quickly. A patch of bare ground around here can disappear in a few weeks. Their goal is to grow and reproduce as fast as possible, so they don’t bother themselves with making trunks but rather madly invest in leaves, leaves, and more leaves borne on the flimsiest of stems. — Robin Wall Kimmerer, Braiding Sweetgrass, 1046
