Fragile Nature

Though it looks burdened, the big-leaf maple actually wants other plants to hitch a ride. By exuding calcium on its bark, the tree attracts a variety of mosses, lichens and other plants. These plants in turn create a nutrient-rich soil the tree absorbs via a secondary root system which covers its boughs. (Image ID: SPO005-00020)
