Why will a skunk control program not produce permanent results?

• A. They are protected by law
• B. They are resistant to traps
• C. Skunks move freely up to 50 km and repopulate areas having fewer skunks
• D. Skunks hibernate annually

Answer: (C)

Long-distance movement and recolonization drive why a skunk control program won’t be permanent. Skunks disperse widely, and individuals can move substantial distances—up to about 50 kilometers. After you reduce numbers in one area, skunks from surrounding areas move in and repopulate the treated zone, so suppression won’t last unless management is extended over a larger landscape and maintained over time. Other factors like legal protections or trap resistance can affect how control is applied, but they don’t explain the quick return as effectively as the animals’ dispersal. Also, skunks don’t hibernate annually in a way that would prevent recolonization, so seasonal dormancy isn’t the reason for non-permanent results.
