Buffer zones are designed to protect which of the following?

• A. Wildlife habitats
• B. Non-target organisms
• C. Sensitive sites
• D. Market yields

Answer: (C)

Buffer zones are a drift-control measure that creates a buffer area around treated fields to keep pesticide residues away from places that could be harmed if exposed. The category most directly protected is sensitive sites—things like streams, lakes, drinking-water wells, riparian habitats, and nearby residences or schools. These zones reduce exposure risk to people and ecologically important places, which is why protecting sensitive sites is the primary goal. While buffer zones can also help safeguard non-target organisms and wildlife, the guidance centers on shielding sensitive sites; market yields are not the goal of establishing a buffer.
