How wolves changed rivers
How wolves changed rivers
At Yellow Stone National park the wolves helped us out by changing the behaviour of rivers.
Para 1
Wolves returned and changed our behaviour of rivers. The river’s started creating pools there was less soil erosion. They meander less. The river changed because of the wolves. Regenerating forests stabilised the banks. The rivers became more fixed.
Para 2
When the wolves arrived they changed the behaviour of the deer.the deer's started avoiding certain places of the park where they could easily be trapped. After the wolf's did that more birds started moving. Songbirds and migratory birds increased greatly. Beavers started to increase because beavers liked to eat the trees. The beavers created dams for other species to live in.
Summary
So altogether the wolves kept the habitats alive and kept the rivers safe at yellow stone national park.
