1. Even though, the eruption of Mount St. Helens volcano was one of the most severe eruptions yet, some plants survived the upheaval. Ecologists were surprised to find the emergence of plants in the mass of ash covered terrain. As the ecologist Dale quoted, “It gave the impression of total lifelessness.” However, roots being guarded in moist soil, resilient plants, and snow sheltering trees were the three main reasons vegetation survived.
2. The plants, and trees that endured the eruption are renown as survivors. Willow, vine maple, black cottonwood, silver fir, and mountain hemlock are the survivors that laid the foundation as a launch for other plants to regenerate off of. Plants regenerated from roots that floated down the river creating a renewed landscape of the past. The roots deposited themselves in the soil, making an emergence of new plants, thus, succession. Moreover, decaying wood that was flowing downstream was also responsible for succession due to the transfer of nutrients, microbes, fungi, and insects.

First, wind was a prominent player in succession by bringing forth spiders, insects, and seeds from outlying areas. A prime example of this, is the pearly everlasting plant which has small seeds, that were easily transported by the wind and captured in the moist soil to create flora. Another factor that caused succession, was moisture. The native flora of the area that was protected under snow (a source of moisture) were able to persevere in this new ecosystem. Lastly, landforms like ponds and springs that were a result of the eruption, became the life source for survivors and new colonizers. These three factors were crucial in order to create habitable environment.
