These include: Volcanic eruptions Retreat of glaciers Flooding accompanied by severe soil erosion Landslides Nuclear explosions Oil spills Abandonment of a manmade structure, such as a paved parking lot While some of these are natural events, some are anthropogenic, or manmade. In the beginning the land will be barren, soon some small plant species will colonize the land (pioneer species), followed by small shrubs, less woody plants and finally trees. Primary succession happens when new land is formed and exposed to living organisms that colonize it for the first time. A receding glacier leaves no earth left. Small plants are gradually being replaced by larger ones on ground that was covered in ash. Energy Management Ecological Succession; Question: Which process occurs after a volcanic eruption?
