This week we have been learning about wolves and the impact they had on Yellowstone national park in 1995.
Here are some facts:
I made this Yellowstone national park in minecraft using minecraft education edition. Yellowstone national park is placed in the USA it is a lot bigger than this. So I don't think I could make the entire thing in a week.
As you can see I have a lot of trees,animals and caves.
In Yellowstone National Park, in America, wolves were eradicated from the environment. This had a detrimental effect on the land as the elk were taking over, eating the shrubs and damaging the environment. The National Park was becoming barren and exposed.
In 1995, wolves were reintroduced into the park where they began a trophic cascade. This is where other species benefit from their presence and the environment flourishes and regenerates .
Because of the wolves in the park, the elk weren’t grazing by the rivers as they could be easily hunted. Some of them were killed for food by the wolves and the elk population slowed With less elk, the trees could regenerate, and in some places their growth quintupled . More trees meant more migratory birds arrived, as well as song birds, and more trees meant more beavers and otters. Bears returned to the area as there were berries and carrion to eat. The carrion that the wolves left behind was attracting rodents and hawks.
The reintroduction of wolves also affected the course of the rivers as the banks became more stable and so they meandered less. Having wolves back in the park had a very positive impact on Yellowstone National Park
Here are so pictures of my world:
