Non Lethal Deer Population Control for Urban and Suburban Environments
(See below for the latest news updates)
Why consider alternatives to lethal control: Cities in the U.S. relying on urban deer culls are about equally divided between using sharpshooters and bow hunters. Although bow hunting is becoming more popular, the Humane Societies of the United States and of Canada recommend against bow hunting to cull urban deer for reasons apparent in the video at right. Based on national statistics, 50 percent of deer hit by an arrow are not recovered [some examples] and death can take 30 minutes to 12 hours. Costs for professional hunters average about $300 to $500 per deer, but vary widely. Although many hunters will not participate in an urban cull, considering it an extermination rather than a hunt, cities often find others willing to pay a license fee to participate. After a cull, however, the remaining deer produce more offspring in response to the increased availability of food and other deer migrate into the area [research support]. Light to moderate long-term hunting, as in many urban culls, does not change the long-run total deer population in an otherwise stable environment. A sterile doe will defend her territory, reducing the in-migration of other deer, one advantage of contraception.
For example, after 10 years of an annual urban cull, the environmental manager for Wilton, Connecticut, concludes "If we harvest 300 a year it could take us maybe seven [more] years.... But of course that does not include baby deer." Rapid City, South Dakota, has been killing deer in the city since 1996 with no measurable effect and at a cost of over $350,000, a program that has recently come under scrutiny. In Lewis Morris Park, New Jersey, an annual deer cull since 1996 produced the following effect: 63.2 deer per square mile in 1996, 65 deer per square mile in 2009. After 17 years of deer culling, the city of Stevens Point, Wisconsin, concluded the deer population was about the same and is looking for a more cost effective solution. Cost analysis typically ignores this effect.
Also confusing the issue are the wide range of unsupported optimal deer density recommendations presented to the public as scientific management goals and the concept that deer culls can generally be used to reduce the risk of Lyme disease, contrary to the overwhelming current research. This Guide to Urban Deer Management contains links to urban news by state giving some history of management efforts, recent efforts in non-lethal control appear below.
Non Lethal Control Methods: In Ashland, Oregon, a change in the fencing ordinance allowing homeowners to build higher fences and a ban on feeding deer resulted in a large reduction of the town's deer population. Fencing is very effective, but can be expensive. Fencing and deer repellents. The city of Sequim, Washington, recently received a state grant to fit their elk with GPS collars with “virtual fence” capability. When alerted, volunteers will be called on to drive the offending elk away from designated areas. Although some have proposed reintroducing predators to control urban populations, safety concerns generally make this unfeasible, but the effects of a predator can be safely reproduced by using herding dogs. Some Canadian towns are experimenting with using herding dogs to manage areas where there are complaints about too many deer. Some wildlife experts suggest that more restrictive leash laws for dogs in recent years have been a factor in encouraging deer to migrate into urban areas and that trained dogs can be used to push deer out of areas where they are causing problems. A well trained herding dog, such as a border collie, can be an effective and safe deer manager. Dogs for Deer Management. Information on the Safe-Capture of Wildlife Using Chemical Immobilization. In all cases, decision makers should be aware that they are designing the future herd based on the population control method.

Cost per deer can be in the two hundred dollar range, but will vary depending local labor costs, number of deer and related issues. Birth control needs to be reapplied after a few years. Success rates are often reported to be in the 90 to 95 percent range. This approach generally has a much lower risk of deer fatalities than sterilization.

Jay Kirkpatrick, Director of the nonprofit Science and Conservation Center in Billings Montana, has used darts to control horse populations for 24 years, and says that darting urban deer is far more effective than hunting them... “Suppose by some magical way, you went in and you reduced the population by 80 percent. Remove them, shoot them. You haven’t solved a problem, because the ones that are remaining behind are still going to breed.” Guns cost between $900 and $3,000. The Science and Conservation Center offers training in Montana for $200 per person, he said – though they waive that fee in cases of hardship. But once employees are trained, the Center sells the vaccine for $24 per dose, and darts cost $2.15.
A U.S.D.A. study concludes "We are confident that GonaCon vaccine will become a valuable addition to the tools used by wildlife professionals to manage populations of overabundant wild animals in settings where other methods such as regulated sport hunting cannot be applied." It has also been shown to reduce traffic collisions.

Testimony from Allen Rutberg, a professor at Tufts University's Cummings School of Veterinary Medicine: The vaccine produced noticeable results in each trial, Gutberg said. On Fire Island, less than 20 percent of does that were treated produced fawns the following year. This trend was accompanied by a 50 to 60 percent decline in the local deer population during an approximately 10-year span. On Fripp Island, the one-shot vaccine had produced an 80 to 90 percent drop in fawning rates....Rutberg said the costs of deer birth control were not inconsiderable. While remote darting of the deer cost only about $80 in the Fire Island program, capturing each deer for vaccination and tagging on Fripp Island cost more than $500.
Ruminant Rumblings May 19, 2011 New York Urban East Hampton StarBy Joanne Pilgrim | The East Hampton Group for Wildlife is advocating a pilot deer-contraception program. Durell Godfrey At a town board session on Tuesday, the East Hampton Group for Wildlife offered to raise money and help the ...Bill Crain of Montauk, the president of the group, and his wife, Ellen Crain, outlined a proposal for a pilot study through which 30 does would be vaccinated with a contraceptive made with a protein from purified pig ovaries, effective for three to four years, and 10 given a placebo. The does would be tagged so they could be monitored for four years to see if they give birth to fawns. Ms. Crain, a professor of pediatric and emergency medicine at the Albert Einstein College of Medicine, said research shows that hunting does not adequately control deer populations, and nationwide studies show that most Americans oppose hunting. The contraceptive vaccine that could be used on the deer has proved to be safe and “not harmful to humans or to animals that eat deer,” Ms. Crain said, and it is used by the United States government to control herds of wild horses in the West. It would be provided for free by its developer, a veterinarian who would also offer his services to oversee an East Hampton pilot study. Dr. Jonathan Turetsky, an East Hampton vet, has offered to oversee care of the deer, Ms. Crain said. The program would have no cost to the town.
ROMANCE WITHOUT RESPONSIBILITIES: THE USE OF FERTILITY CONTROL TO MANAGE BISON ON CATALINA ISLAND CALIFORNIA. Western Wildlife Society Meetings, 2012, Calvin Duncan; Catalina Island Conservancy; PO Box 2739, Avalon, CA, 90704; 310-510-1299 x232; email@example.com; Julie, L,king
We evaluated the cost, administration efforts, and efficacy of porcine zona pellucida (PZP) immunocontraception for the contraceptive management of an introduced herd of American bison (Bison bison) on Santa Catalina Island, California. A roundup was completed in 2009 whereby 35 of the estimated 47 breeding age bison cows were temporarily restrained, ear tagged, and given an intramuscular inoculation of 100µg PZP mixed with 0.5ml of Freund’s Modified adjuvant (FMA) as a primer. The remaining 12 unmarked cows received the same PZP and FMA emulsion via field darting efforts completed in February and March 2010. As per PZP administration protocol, a pre-rut dose of 100µg PZP mixed with 0.5 ml of Freund’s Incomplete adjuvant (FIA) was administered intramuscularly to all 47 breeding age bison cows via field darting efforts conducted mid April through July 2010. The pre-rut darting efforts were completed during 12 daily attempts and required approximately 45 hours of field time. Through our monitoring efforts in 2011 we demonstrated that the contraception effort had successfully held the calving rate below the estimated annual mortality rate of 4%, and therefore proved to be an effective means of maintaining a stable bison population.
TESTING THE EFFECTIVENESS OF ONE-SHOT IMMUNOCONTRACEPTIVES ON WHITE-TAILED DEER AT FRIPP ISLAND, SOUTH CAROLINA
Both distance-sampling and mark-resight methods indicated a decline in deer densities and fawn-doe ratios on Fripp Island in 2008. Between 2006 and 2008, deer numbers appear to have declined between 21-35% on Fripp and fawn:doe ratios have declined by 38-56%. Both measures remained roughly stable on the Hunting Island control site during that period. There is also a trend for increased male:female ratios over the course of the study on both sites, for reasons that are not well understood. - Allen T.

Evaluation of a Trap-Sterilize-Release Program for White-tailed Deer Management in Highland Park, Illinois, 2002-2005 September12, 2005, by Nancy E. Mathews, Ph.D [Full article in attachment at bottom of page]
.... We found that sterilization can control the deer population in Highland Park at the goal population level of 5 deer per mi2, if we can capture and sterilize an average of 32% of the female population per year. Our computer model suggests that the long-term maintenance of the population will require sterilizing an average of 6 does per year. Sterilizing more females will result in achieving the population goal more quickly. The model projections suggest that the population will continue to grow initially and peak at 3.7 years, until the effects of sterilization halt population growth. There after, the population will decline and hover around the target density after 9.5 years.
We evaluated the influence of sterilization on the behavior (home-range size and dispersal rates) of the sterilized and control deer. In general, deer used extremely small home ranges in this urban environment and there were no differences in either the home range sizes or dispersal rates of sterilized deer verses the control deer. Fawns used larger home ranges than adults, and home ranges were larger during the winter. Although the sample size is exceedingly small, we found that more treatment deer than control deer made exploratory movements out of their home range. There is also an initial indication that sterilized deer traveled farther and used larger home ranges than control deer.
With respect to the efficacy of surgical sterilization under field conditions, we found that tubal ligation, by ventral laparotomy, provides a safe, humane form of sterilization with low mortality
in white-tailed deer. The ability to capture, chemically immobilize and perform surgery on wild deer, under field conditions was highly successful.
Officials Work To Spay Deer To Reduce Their Population « CBS Baltimore
Feb 14, 2011 ... Spaying to control the population of domesticated animals is being given a try in the wild. Contraceptive darts have been tried before in Maryland but they must be administered once a year. It takes money and time to control reproduction.
The $50,000 spaying pilot has made for some strange bedfellows. Feinberg is an animal welfare advocate who has carried out a tireless campaign against what she sees as a state bureaucracy that is too quick to use hunting as an answer to deer problems. The professional she hired is Tony DeNicola, a biologist with a doctorate and a national reputation as a deer sharpshooter. The money is from the estate of Gerda Deterer, an animal rehabilitation expert who died in 2009. And the DNR — Feinberg's frequent adversary — approved the effort.
White Buffalo can sterilize five to seven deer a day vs. shooting 10 to 15 a day. July 2007, Cornell University began a five-year, $500,000 deer management plan that used hunting and surgical sterilization to reduce the campus herd by 75 percent. On a 1,133-acre portion of the central campus, 77 does and fawns have been sterilized. On a patchwork of 2,544 outlaying acres, hunting is permitted and 181 deer of both sexes have been killed.
The results will be out next spring, but critics have dubbed the experiment as "Spay and Slay" and consider it a waste of money.
In 2009, the wealthy St. Louis suburb of Town and Country decided to go a similar route and hired DeNicola's company, White Buffalo Inc., to kill 112 deer and spay another 100 at a cost of $150,000.
Are Wildlife Services Reluctant to Spay or Use Contraceptives?

"All they want to do is shoot, trap and poison," said Wolf. "They don't want to consider anything else."
A common objection to relocation is that many deer perish as a result, since deer are flight animals and easily stressed by any constraint. A 2008 study in Texas where there had been significant experience with Trap, Transport, and Transplant concludes "reasonable survival rates can be achieved." (see research below).
As the information below suggests, success varies widely depending on circumstances. Also, the potential of spreading Chronic Wasting or other diseases should be considered: Geography of Chronic Wasting.
Survival and Movements of Translocated White-tailed Deer in South Texas
2008 Proc. Annu. Conf. SEAFWA, Aaron M. Foley, et al
Abstract: In south Texas, white-tailed deer (Odocoileus virginianus) translocations have become a common technique for non-lethal means of deer removal with the implementation of a Trap, Transport, and Transplant (TTT) permit program. However, the effectiveness of TTT as a management tool has not been evaluated. We monitored survival, movements, and body condition of 51 adult white-tailed deer from two translocations to two south Texas properties, one of which was partially enclosed by a 2.5-m net-wire fence. Annual survival of all translocated deer was lower in the partially fenced property (64%) compared to the unfenced property (80%), but overall survival was similar to survival rates of adult native south Texas deer reported in previous studies (68%–74%). As expected, more deer left the unfenced property (52%) than the partially enclosed property (14%). Cumulatively, 40% of deer survived and remained on the release area after one year. Young (1.5–3.5 years old) translocated males had below average antler gain, body condition scores, and rump fat measurements 6–8 months post-release compared to resident males. Results of this study indicate reasonable survival rates can be achieved, but released deer may not remain in the vicinity of the release site and tend to have below-average body condition 6–8 months after release compared to native deer.

A Connecticut guide to deer management cites the study above and concludes: "Survival rates of relocated deer are frequently low. The poor physical condition of deer from an
overpopulated range predisposes them to starvation. Trap-and-transfer efforts in California, New Mexico and Florida resulted in losses of 85, 55 and 58 percent, respectively, from 4 to 15 months [p. 15]" The guide references the Texas study above, but does not provide any information about the relative success of that much more recent effort. The California case was an unusual effort to transfer deer from an island into a very different environment.
The Connecticut guide does not report the low mortality rate from the study below, instead summarizes as follows: "A six-year study of translocated deer from the Chicago Metropolitan Area showed a higher annual survival rate of resident adults than for those translocated deer. Deer-vehicle accidents were the largest source of mortality among the translocated does and presumably resulted from unfamiliarity with the release site (18)" see page 16
Post-translocation survival and movements of metropolitan white-tailed deer. (1990) Jones, J. M. and J.H. Witham. Wildl. Soc. Bull. 18(4):434-441. Here are some of the conclusions of this study:
"Survival of translocated deer ... has been documented in other studies. Direct comparisons of these studies are complicated by differences between sites, methods of translocation, and methods of calculating and reporting survival rates. These data suggest, however, that the survival of translocated deer is contingent upon capture and handling procedures, the nutritional status of the animals, and the presence of decimating factors at the release site including hunters, vehicular traffic, predators, or a combination of these. ... Capture myopathy ... was presumably the cause of 3 (12%, 2 adults and 1 fawn) mortalities among our translocated does within 0.8 km of release site during the first month post-releast." (page 5)
