Yellowstone national park USA
wolves kill but also give life
the population of deer grew because wolves had been away for 70 years
wolves kill deer but also move them away to safe area's
most place regenerated
talking about the trees like willow growing
birds started moving in
beavers increased
beavers making dams help the otters and muskrats and stuff
the wolves killed coyotes
that made the number of rabbits and mice
that means more hawks more stoats and weasels and foxes badgers ravens and bald eagles
bears began to rise
the wolves change the behavior of the rivers
the rivers change response to all of this
the wolves transform the Eco system
