We don't have wolves, but coyotes are sure a problem.
The Quality Deer Management Associations 2010 Whitetail Report covered several coyote studies. The following are quotes from the report.
Cory VanGilder, University of Georgia, conducted a study along with Drs. Grant Woods and Karl Miller. They studied the effects of intense predator removal on whitetail deer recruitment in northeast Alabama. They removed 22 coyotes and 10 bobcats from February through July 2007 on a 2000-acre study site. This reduced the predator abundance indices to nearly zero immediately prior to the fawning season. The result was drastically increased fawn survival from 193 to 256 percent.
University of Georgia student, Bret Howze conducted an even more ambitious study along with Drs. Robert Warren and Karl Miller of predation and whitetail deer recruitment in southwest Georgia. Their study identified two study areas. One 11,000-acre block had 23 coyotes and 3 bobcats removed between January and August 2008. A second 700-acre block was used for a control area and no predators were removed. They revealed that 2 fawns were recruited for every 3 does in the predator removal zone, while it took over 28 does to recruit the same number of fawns in the zone where predators weren’t removed.
