Gophers benefit humans and ecosystems in several ways. As with all burrowing animals, gophers are doing wonderful things for the top soil in the areas where they live.  The burrowing process aerates the soil, reduces compaction, and increases water filtration.  Living underground has is benefits, too, by adding nutrients to soil through natural composting of nesting materials and, believe it or not, regular excrement. 

Unfortunately, those large incisors can have a negative effect to humans when they accidentally chop through plastic water lines and underground sprinkler system.  The mounds formed during the burrowing process have been known to dull the blades of harvesting equipment and may not be fully appreciated by the homeowner who prides themselves on a pristine lawn and garden.

The presence of gophers can also make the area more preferable for badgers which can cause considerable damage to yards and gardens.
