When the habitat of these birds is destroyed, insect populations increase and can harm the land. Loss of shade leaves the forest floor exposed to extreme heat. A variety of organisms and plants necessary for forest survival can be damaged. Poor moisture retention in the ground, because shade has disappeared, makes for potential fire hazards. Amphibian populations which thrive in the moisture rich soil on the forest bottom, can be damaged because of soil disturbance and loss of water quality.
Open areas can give way to undesirable plant species as they begin to grow back.
Mud in waterways destroys plants and microscopic organisms that fish and other aquatic life need to survive. Fishing and swimming become poor. Drinking water supplies can become dirty. Roots of trees which have been cut begin to decay. They give way to loose topsoil and erosion on land and along stream and river banks.
