Pocket gophers and moles are helpful to the environment because

• A. Their tunnels allow air and water to penetrate the soil
• B. They increase soil salinity
• C. They compact soil
• D. They deter beneficial microbes

Answer: (A)

The big effect is that their burrowing creates air spaces in the soil, which improves aeration and water movement in the root zone. Those tunnels act like natural macropores, letting oxygen reach roots and facilitating rainwater and irrigation to infiltrate instead of just pooling or running off. This enhances root health, supports beneficial soil microbes, and improves drainage and nutrient cycling, all of which help turf and plants grow more robustly. The other ideas don’t fit this benefit: burrowing does not raise soil salinity, it loosens rather than compacts soil, and while it disturbs microbes, the overall impact is more about fostering a healthy soil structure and microbial environment than deterring them.
