Which pest is most commonly associated with girdling the base of young trees at the ground line?

• A. Mole
• B. Vole
• C. Gopher
• D. Rat

Answer: (B)

Girdling the base of young trees at the soil line disrupts the phloem, stopping nutrient flow from the canopy to the roots and causing the tree to die from the bottom up. Voles are most often responsible because they live close to the ground and feed on bark right at the base of saplings, creating a clean, circumferential girdle around the stem. Moles mainly tunnel underground and leave surface ridges and mounds, not a circular bark slice at the base. Gophers focus on roots and crown areas, and while they can weaken plants, their typical damage isn’t the neat girdle around the base. Rats can gnaw bark, but the characteristic ground-line girdling pattern is most closely associated with voles.
