Placement of electrical lines on the landscape is increasingly recognized as an important factor contributing to avian mortality. Birds are more susceptible to line collisions if lines cross flight paths or movement corridors. This could be compounded if vegetation surrounding the lines is not tall enough to reach the line, as with early successional habitat. A solid row of vegetation at or above the height of the line acts as a flight barrier to large birds, forcing flight paths above the electrical lines, thereby reducing the risk of collision.
