21.5.19 Purpose: Audience:kauri hub teachers Plan:right there How wolves in yellowstone national park changed the river. Introduction:in yellowstone park wolves where put back in the park after 70 years and this changed the park.The deer where destroying the park but but the wolves made this change. Wolves ate the deer so there was less deers in the park to eat the trees so the trees grew back. More trees so that meant more birds and beavers came back to the park. The beavers made dams in the river the dams caused ducks , rats , fish and reptiles to come back into the park. The river changed and became bigger because the trees and plant roots helped the river bank to stay witch made the river cleaner and bigger.
