What did the 1980 mount saint helens volcanic eruptions teach environmental scientists? planting douglas fir trees was essential to recovering the forest. salvage logging was essential to protecting the area from fire an insect threats. seating the slopes was necessary to prevent erosion. many of the initial pioneering species actually survived the eruptions.

The 1980 eruption of the mount saint Helen's volcano taught scientist and humanity many things. Scientists learned that there would be a need to replant the devastated forest. They chose Douglas fir trees as the essential species to repopulate the scorched lands.

Many of the initial pioneering species actually survived the eruptions.

1980 Mount Saint Helens volcanic eruptions were efficient to teach scientists about the ecological relationships and succession after volcanic activity. Charlie Crisafulli was a ecologists who arrived at the volcanic site along with his colleagues to collect ecological data. He noted the development of ecological relationships across the volcanic landmass. He documented the types, amounts and distribution of surviving organisms, which further took forward the responsibility of colonization and succession.

     {EIGHT}For now, astronomers count eight main rings. As they were discovered, each was assigned a letter of the alphabet (not exactly the flashiest nomenclature for such an awe-inspiring planet). But they do not appear in alphabetical order. Working outward from Saturn, the first are the C, B and A rings
