![]() ![]() Warm-season prairie grasses have relatively large roots, which are sufficient for sustaining Geomys. This method is less effective for plains pocket gophers, as they can survive on grasses. ![]() Plant 50-foot buffers of grain around hay fields to render the habitat unsuitable for pocket gophers and to minimize immigration by pocket gophers.Ĭontrol forbs that have large underground tap roots by chemical or mechanical means, to minimize damage by Thomomys to rangelands, orchards, and shelterbelts. Plants that produce grain do not establish large roots for storage, so there is insufficient food to sustain pocket gophers year-round. When alfalfa is rotated with grain crops, the resultant habitat will not support pocket gophers. Losses of 30% were reported in hay meadows. Plains pocket gophers reduced forage yields in eastern Nebraska by up to 46% in dry land alfalfa and 35% in irrigated alfalfa. Most use of traps and toxicants should occur during spring and fall when pocket gophers are building mounds.īotta’s pocket gophers at a density of 32 per acre decreased the forage yield by 25% on foothill rangelands in California, where the plants were nearly all annuals. Pocket gophers can be controlled effectively whenever new mounds are being constructed.
