“…This density is the maximum carcass density observed by Sullivan (1982) using bait stations containing anticoagulants in similar situations. Five carcasses per day were placed on each study site for four consecutive days for a total of twenty carcasses per site.…”

A field study was conducted in Lewis and Clark County, Montana, during the summer of 1986 to determine the fate of Columbian ground squirrel (Spermophilus columbianus) carcasses in the environment. Ground squirrel carcasses were marked with radio transmitters and placed in situations and locations similar to those found in actual rodent control operations. Carcasses were monitored until their fate was determined or until they were no longer considered attractive to scavengers. Red fox (Vulpes fulva) was the primary scavenger in this study. Striped skunk (Mephitis mephitis) and birds (corvids and/or raptors) were the other mammalian and avian scavengers identified. Carrion-eating insects quickly attacked the carcasses and were important in determining the maximum exposure time of the carcasses to scavengers. Factors determining the risks to scavengers from rodent control operations and management techniques to reduce nontarget hazards are discussed.

“…These situations were based on locations of squirrel carcasses found after actual rodent control operations (Sullivan 1982). These locations were designated in the following manner: LI: Burrow Opening -0% cover; L2: 0 -25% cover; L3: 25% -50% cover; L4: >50% cover.…”

A pelleted grain bait containing 0.005% brodifacoum was placed in bait stations to determine effectiveness for managing Columbian ground squirrels. Ground squirrel activity, measured by direct visual counts, was reduced an average 96.84% (range 95.43-100.00) on 3 treated plots. A total of 11.55 kg (25.46 lb) of bait was consumed by squirrels in treating 3.87 hectares (9.56 acres) of pasture or hayland.

“…Bromadiolone is an anticoagulant rodenticide that is registered by the U.S. Environmental Protection Agency for control of commensal rodents. This rodenticide may be effective for control of field rodent species (Marsh 1977;Sullivan 1982aSullivan , 1982bSullivan , 1983 including pocket gophers (Marsh 1977) and investigations are needed to make this determination.…”

Efficacy of two bromadiolone whole wheat baits (50 ppm and 100 ppm AI) and one strychnine whole barley bait (500 ppm AI) was tested for control of the northern pocket gopher. Bait was applied under field conditions using a tractor-drawn burrow builder. The bromadiolone baits averaged 8.5 and IV. percent reduction in activity for the 50 ppm and 100 ppm baits, respectively. The 500 ppm strychnine bait averaged 52.8 percent reduction in pocket gopher acti'^^ity. Bait acceptance test showed 90 percent and 67 percent removal of the strychnine and bromadiolone test baits, respectively.
