Which action is an example of using randomness in wildlife management strategy?

• A. Move scare tactics around and deploy at different times of day
• B. Combine scare tactics with rotating repellents to keep pests unfamiliar with the environment
• C. Grow very quickly; highly competitive; produces abundant, long-lived seeds; reproduces vegetatively
• D. Non-native introductions are troublesome

Answer: (A)

Unpredictability in deterrence helps prevent wildlife from habituating to scare tactics. When animals encounter a threat that’s always in the same place and at the same time, they quickly learn it’s not dangerous and ignore it. Moving scare tactics around and deploying them at different times of day keeps the animal guessing about where and when the next scare will occur, maintaining the perception of risk and making the deterrent more effective overall. Rotating repellents can also vary stimuli, but randomness—changing both location and timing in an unpredictable way—strongly disrupts the animal’s ability to anticipate the threat. The other options don’t involve this kind of behavioral disruption: one describes rapid plant growth traits unrelated to deterrence, and the other mentions introducing species, which is a different, ecological risk rather than a randomness-based strategy.
