Pocket gophers and moles contribute to soil health by the action of their tunnels, which

• A. Allows air and water to penetrate the soil
• B. Creates permanent soil instability
• C. Causes excessive soil compaction
• D. Prevents microbial activity

Answer: (A)

Air and water moving through soil depend on pore space. The tunnels created by pocket gophers and moles form channels that act as macropores, letting air and water infiltrate and drain more efficiently. This improves oxygen availability for roots and soil microbes, supports healthier root growth, and enhances soil drainage—all of which contribute to a healthier turf soil profile. The other statements don’t fit because tunneling, by creating these voids, tends to relieve compaction locally and promote drainage and aeration rather than causing instability or excessive compaction, and it supports microbial activity rather than suppressing it.
