Non-Lethal Deer Population Control for Urban and Suburban Environments

See below for the latest news updates  Also see Deer Fence, Deer Resistant Plants and Repellents, Transportation Safety, Deer and Lyme Disease, Contraception Research, Dogs for Deer Management, a deer sterilization project at Cornell, the Botstiber Institute.  

Deer Culls used to manage suburban deer create a public safety issue and provide only a short term solution, requiring a perpetual killing program.  Examples of the Perpetual, Annual Deer Cull.  Many people don't want their neighborhood deer to be slaughtered. Deer are edge dwellers, living at the interface of the meadow and the thick forest.  A lush suburban habitat can support more deer, the carrying capacity, than a forest.  


Communities wanting fewer deer can reduce the carrying capacity using fences, deer resistant landscaping and repellents.  Deer fence is a good long-term solution because it reduces the food available to the deer and that will reduce their population over time.  Examples of  other non-lethal approaches.  Information below for contraception, sterilization, and relocation.  A ban on feeding deer is often a first approach, sometimes a required approach.  Also a deer population survey.


Deer culls using sharpshooters or bow hunters may not be feasible in suburban environments because of public safety concerns.  Bow hunting is becoming more popular, but even under the best conditions a significant number of deer are likely to be wounded [graphic examples] and not recovered by archers, 50 percent rates are reported in the literature

 

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.  Professional sharpshooters improve public safety and kill efficiency, but costs run from about $300 to $1,000 per deer. Below a video of the trap and kill method used by many deer exterminators, including Cornell.

Deer respond to a cull with increased fertility, producing more twins and triplets, and a larger proportion of female fawns that will further increase the deer population -- the Rebound effect in the figure above [research support] --compensatory reproduction, also observed in mountain lion and coyote populations.  


Light to moderate hunting, as in many urban culls, does not change the long-run total deer population in an otherwise stable environment.  More dramatic culls, keeping the deer population at about 50 or 60 percent of the carrying capacity, achieves the maximum sustainable yield, the largest number of deer than can be killed annually while maintaining the population.  Also, other deer attracted by available food may migrate into the area, although suburban does have very small ranges and migration rates will depend on local factors.  A sterile doe will discourage new deer from entering her territory, the "placeholder" effect, and eat food that would result in more fawns from fertile does. 


The result of a cull is a future, perpetual negative cash outlay for communities and lots of slaughtered deer.  Cost analysis of urban deer cull programs typically ignores the future cost of maintaining the program and also ignores the intrinsic value of the life of each deer.   The January 2018 issue of Wildlife Professional advises that it is a myth that wildlife populations need to be hunted or harvested to control populations [p. 28].  


Confusing the public debate are the wide range of unsupported optimal deer density recommendations presented to the public as scientific management goals (deer density and forest regeneration) and the concept that deer culls can generally be used to reduce the risk of Lyme disease, contrary to most of the current research. Some states are requiring hunting to be the only method of deer control in suburban areas, ignoring local local decisions.  In all cases, decision makers should be aware that they are designing the future herd based on the management method.  

News and reports below about three types of population control:

 contraception, sterilization, and relocation.

Deer Contraception

Birth Control Research


Products: Gonacon, Spayvac a PZP (porcine zona pellucid)  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, up to six years for Spayvac, but the time is being extended as the technology develops.  Success rates are often reported to be in the 90 to 95 percent range.  This approach generally has a lower risk of deer fatalities than sterilization.  


A private effort to experiment with contraception in British Columbia. The U.S. Humane Society provides this service, contact information and an example proposal.  The nonprofit Science and Conservation Center in Billings, Montana, has many years experience working with horses, deer, and other animals.   On July 6, 2017, the EPA approved an application to register ZonaStat-H, a fertility control vaccine that will provide a humane management tool for managers of deer populations.

Sterilization


While spaying can be expensive, $500 to 1,500 per deer, because of high labor costs, local volunteers can bring costs down.   In many states, deer contraception is illegal.  Sterilization is typically 97 to 100 percent effective and only needs to be done once, but may result in the death or injury of some deer . This field surgery requires more supplies and equipment than contraception so easier access to deer such as through small roads becomes an issue.  Tubal ligation requires less intervention than spaying or ovariectomy, but will result in does going into heat which may attract bucks into the area.  Ovariectomy avoids this problem.  A paper summarizing successes.

Relocation, Translocation


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).  Costs can be as low as $150 to 200 per deer.   


 As the information below suggests, success varies widely depending on circumstances. Significant deer mortality may result from from the difficulty of adjusting to a new environment and the transportation stress, although wild deer are routinely transported for deer research.  As with a cull, if there is ample food the remaining deer will respond with increased fertility.  Also, the potential of spreading Chronic Wasting or other diseases should be considered and has prompted some states to avoid relocation strategies.
