The four pocket gopher species found in Colorado are distributed almost entirely in different areas (Figure 1), possibly because of different ecological requirements or competition. Plains pocket gophers (Geomys bursarius) are abundant in sandy and silty soils of the plains but are not abundant in compacted soils.
Gophers dig holes to eat plant roots. Burrowing animals are the prime suspects when a homeowner discovers tunnels and holes in the yard. Many kinds of small animals, such as moles, voles, chipmunks and rats, make holes in the ground. Some, such as moles, create complex tunnel systems, while others, such as rats, dig burrows in which to hide.
