What is the purpose of the three-dimensional nature of some fences?

• A. It deters deer from jumping by adding a multi-layer barrier
• B. It improves wind flow
• C. It increases cost
• D. It reduces maintenance

Answer: (A)

Three-dimensional fence designs add depth and multiple planes to the barrier, creating a more complex obstacle that is harder for a deer to clear. The extra surfaces change how the animal approaches and takes off, effectively increasing the obstacle height and making the jump less appealing or more easily misjudged. That increased difficulty is what makes the fence better at preventing deer from crossing.

Wind flow, cost, and maintenance are not the primary reasons for this design—the goal is to keep deer from jumping over by presenting a tougher, more discouraging barrier.
