RGS are an important part of the ecosystem. They are a major food source for wildlife such as hawks, owls, eagles, coyotes, foxes, snakes, bobcats, and weasels. However, they can also cause damage to lawns, gardens, parks, and infrastructure.

When RGS establish colonies in public areas, their tunnels and burrows can affect how park spaces are used, damage underground structures, and increase erosion on slopes. In some cases, burrow openings can create safety hazards for people and pets in playgrounds and sports fields. In natural areas, however, burrows may have little or no impact.

Finding a balance between protecting wildlife and managing impacts is important. This helps support biodiversity while reducing problems for people using parks and other public spaces.

It is not unusual for RGS to dig tunnels under driveways, patios, and other areas around urban homes. Ground squirrels prefer open spaces where they can easily see around their burrows. Keeping grass longer, installing privacy fencing, or using barriers can block their view and make an area less attractive for a colony.

Rodent-resistant landscaping, barriers, and certain plants may help discourage ground squirrels. Keeping yards free of clutter and filling or addressing new burrow openings quickly can also help reduce activity on your property.

If you notice a large colony of RGS in a park or other public space, please report it through 311 so the area can be assessed.
