As I walk through the broomsedge in June, dozens of grasshoppers clatter away with every footstep. Bees and wasps wing past, leafhoppers spring, and beetles scurry for cover. This productivity is why so many birds depend on grasslands for their breeding or wintering. Grasslands, especially those in humid areas with good soil, provision their local food webs as richly as do forests.
Grasses also build soil. Their leaves send about two thirds of all the food they make to the underworld. There, roots tunnel many meters down. As they grow, they break up clay and rock, exude sugars and other molecules, and interweave their cells with fungi. When the roots die, they add spongy organic matter to the soil. This soil‑building process is so productive that it lifts the ground. When a degraded grassland returns to health, the ground heaves up, as if inhaling with relief.
