Explanation:

Yellowstone National Park is a natural  paradise with over 70 species of birds,which  include  trumpeter swans, sandhill cranes, loons, peregrine falcons, osprey and bald eagles

The Greater Yellowstone Ecosystem, with Yellowstone at its core, is one of the largest nearly intact temperate- zone ecosystems on Earth. It has an area of 12–22 million acres; 18,750– 34,375 square miles

Temperate ecosystems are the ecosystem that are characterized by the  seasonality in temperature, with cooler winters and warmer summers, and also  show various  seasonality in precipitation patterns, resulting from seasonal changes in the orientation of Earth's axis relative to the sun.

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.
