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.
In Arizona, pocket gophers may produce young throughout the year. At higher altitudes young are produced mainly in June and July and one litter is produced per year. At lower elevations, there may be two litters produced per year with young born mainly from December through May and from mid-July through August.
