What is one of the main purposes of maintaining a buffer area adjacent to a sensitive location?

Maintaining a buffer area adjacent to a sensitive location serves the important purpose of protecting those sensitive areas from contamination caused by aerial applications. Sensitive locations often include water sources, habitats for endangered species, and residential areas, where exposure to chemicals can lead to harmful effects on the environment and health. The buffer zone acts as a safeguard, absorbing or deflecting potential drift of pesticides or fertilizers, thereby reducing the risk of unintended exposure that could harm non-target organisms or the ecosystem.

While the other options may present benefits in different contexts—such as enhancing visibility for application or aiding in navigation—they do not address the primary concern of preventing contamination in sensitive areas. The core goal of establishing a buffer zone is to ensure ecological integrity and safety, making the correct answer a crucial aspect of responsible aerial application practices.
