Can Biomes change?
Changes in climate, volcanoes, earthquakes, fires and weather can change a biome. If an ecosystem can change, a biome can too.
I think that Mount St. Helen’s volcanic activity definitely changed
the ecosystem and even the physical structure of its surrounding area.
The blast zone was devastating.
Here is an interesting map showing the area before and after the blast.
Some of the insects, like the bees and grasshoppers were affected by the eruption. The ash is lethal for these insects.
Besides the volcanic eruption, one little caterpillar had an impact on Mont St Helen’s ecosystem.
Biomes can change in a profound way.
