Someone once told me that bare soil is like a wound in the earth. It’s unnatural for soil to be exposed, so nature fills the gap, starting with weeds that grow from existing roots or from seeds carried by the wind. These weeds act like a scab, stopping soil from washing or blowing away and providing ground cover for insects, reptiles, and small mammals. From small beginnings, larger plants can grow, up to and eventually including the regeneration of forests.
