One example of primary succession takes place after a volcano has erupted. The lava flows into the ocean and hardens into new land. The resulting barren land is first colonized by pioneer organisms, like algae, which pave the way for later, less hardy plants, such as hardwood trees, by facilitating pedogenesis, especially through the biotic acceleration of weathering and the addition of ...

Poor land management, due to decades of clearcutting and overgrazing, led to soil erosion and a preponderance of caliche. The ashe juniper was one of the few plants that could thrive in the rocky soil.
