Date of this Version
Data for this report were gathered from three different contractors working on a service contract for the Butte Falls Ranger District of the Rogue River National Forest in southwest Oregon to control pocket gophers (Thomomys spp.). Other data were collected from formal open-hole inspection plots. These plots were also the basis for payment on this contract. Issues of concern on this project were: 1) Production. Could we treat enough acres of the high-risk plantations in the City of Medford Municipal Watershed; 2) Control effectiveness? Could we reach a control comparable to strychnine-treated grain; 3) Cost effectiveness? Would bid prices be low enough to treat enough acres without depleting our budget; and 4) Effect on nontarget species?
