DEER

Q: AREN'T DEER HERDS

INCREASING?

A: In the last century, the U.S. deer

population has grown from fewer than

500,000 to more than 14 to 20 million.1

This is primarily because state wildlife

agencies view themselves as providers or producers of deer for sport hunting.2 Because of a growing human population and increased development infringing on wildlife habitat, deer densities appear to be higher than ever in suburban areas. People are coming into more contact with deer due to factors that include ornamental shrubs, private and commercial gardens and orchards that are attractive to deer, the "edge" habitat created by roadsides, suburban lawns, and deserted farmlands that generate large amounts of grazing and browsing for deer, roadways and highways that tend to concentrate deer in certain areas, and the eradication of predators such as wolves and mountain lions.3

Q: ISN'T HUNTING DONE TO KEEP DEER FROM OVERPOPULATING?

A: Hunters in the U.S. kill approximately 6 million deer each year, representing 4.5% of the 134 million animals killed annually by sport hunters.4 While hunters try to justify their entire sport based on deer overpopulation, deer represent only a minuscule fraction of overall hunting activities. The millions of mourning doves, rabbits, squirrels, waterfowl, and other animals hunters kill are never considered overpopulated. Hunters and wildlife agencies are not concerned with reducing deer herds, but rather with increasing or maintaining the number of targets for hunters and the number of potential hunting license dollars. Thus, they use deer overpopulation as a smokescreen to justify their sport. The New Jersey Division of Fish, Game and Wildlife states that "the deer resource has been managed primarily for the purpose of sport hunting,"5 and hunters readily admit, "deer hunters want more deer and more bucks, period."6

Q: BUT WE NEED SOME MANAGEMENT, DON'T WE?

A: The current system of wildlife mismanagement has been directly responsible for the rise in conflicts between deer and people. Managing deer herds for the sole interest of providing enough targets for sport hunters has wreaked havoc on deer and on the animals who share their ecosystems. For example, Michigan has a "Deer Range Improvement Program" (DRIP) that earmarks $1.50 from each deer hunting license sold into a fund specifically designed to increase deer reproductivity and to maximize sport hunting opportunities. According to a 1975 newspaper report, three years after the DRIP program began, "The DNR's Wildlife Division wants to keep clear-cutting until 1.2 million acres of forest land -- more than a third of all of the state-owned forest -- have been stripped . . . the wildlife division says it is necessary because a forest managed by nature, instead of by a wildlife division, can support only a fraction of the deer herd needed to provide for half a million hunters."7 Since that prophetic 1975 report, the number of hunters in Michigan has doubled and the state's deer herd has tripled.

Q: DOESN'T HUNTING KEEP DEER NUMBERS DOWN?

A: While it is indisputable that hunting removes some animals from the population, it does not keep deer populations at a continually reduced level. While the average fall hunting season may remove 20-30% of the deer from a population, surviving deer will have less competition for food and increased nutritional health. Several scientific studies indicate that better-nourished deer have higher productivity,8 lower neonatal mortality, increased conception rates,9 and increased pregnancy in yearlings.10 In hunted populations, does are more likely to have twins rather than single fawns, and are more likely to reproduce at a younger age, thus helping the population grow even faster. One study even indicated that "twinning was 38% on hunted and 14% on nonhunted" deer populations.11 Because hunting pressure is focused on bucks, hunting skews the sex ratio of deer herds and leaves more females to reproduce (there have been reports of "does outnumbering bucks by as much as 30-1").12 In these skewed sex ratios, a single buck can impregnate every doe in the population. Since hunting may cause the reproduction rates of a deer population to double or triple, hunting is not a solution to a problem.

Q: DON'T WE NEED HUNTING TO STOP DEER FROM INVADING SUBURBAN AREAS?

A: State wildlife officials have duped urban and suburban communities into believing that hunting will solve conflicts between deer and human residents, and these communities tend to lean toward bowhunting or muzzleloading weapons because they fear the use of high-powered rifles or shotguns in residential areas. Yet, these two cruel and primitive methods of hunting do not reduce deer populations due to their extremely high crippling rates. Dozens of scientific studies indicate that bowhunting yields more than a 50% crippling rate.13 For every animal dragged from the woods, at least one animal is left wounded to suffer -- either to bleed to death, to become infested with parasites and diseases, or to live as a cripple. One study even indicated that "100-200 archers per square mile per day would be necessary to achieve a satisfactory deer harvest."14 Muzzleloading equipment, because of the lengthy amount of time it takes to reload, also yields a high incidence of crippling. Hunter education manuals indicate that while a deer shot with a rifle may take 5-10 minutes to die, an animal shot with a muzzleloader may take 60-70 minutes. Bowhunting and muzzleloading deer hunts may be psychologically soothing to landowners, but wounding animals at random does little or nothing to stop conflicts between deer and people.

Q: DOESN'T HUNTING STOP DEER FROM EATING ORNAMENTAL FLOWERS AND ENDANGERED PLANTS?

A: Killing some deer because we want to protect certain vegetation does not stop the surviving deer from eating those same plants. What we need are site-specific mitigation measures that have proven to be both humane and effective. With high-tensile wire fencing, electric fencing, and the planting of vegetation that is unpalatable to deer, deer problems can be resolved or reduced. The California Department of Fish and Game distributes a free brochure detailing a "complete list of 'deer-resistant' plants, deer repellents and fencing techniques designed to minimize garden and landscape damage by deer,"15 and the New Jersey Division of Fish, Game and Wildlife donates materials to farmers and homeowners who report deer damage -- including barbed wire and high-tensile electric fencing, and repellents.

Q: WON'T HUNTING SAVE OUR FORESTS FROM DEER OVER-BROWSING?

A: Deer grazing and browsing can create a browse line in a forest and can affect other species; however, ecosystems go through cyclical stages and these impacts are not permanent. Blaming deer for the loss of our forests and decrease in understory vegetation does not take into account the multitude of factors that contribute to these findings. Changes in climatic conditions and lack of natural forest fires largely add to the modifications in our landscapes. In addition, urban sprawl affects both deer and our forests through loss of habitat and the destruction of our forests.

Q: DOESN'T HUNTING REDUCE AUTOMOBILE ACCIDENTS?

A: While public officials tend to blame an increase in deer-vehicle collisions on an increase in the deer population, such collisions are more often the result of more roadways being built, more people driving, and roadways bisecting deer habitat. Killing some deer does absolutely nothing to prevent the surviving deer from crossing the exact same roadways at the exact same "deer hot spots." Virginia hunters, for example, killed 179,027 deer in 1998, and Virginia drivers collided with 4,024 deer that same year. In 1999, Virginia hunters killed 188,757 deer and drivers hit 4,470 deer.16 Clearly, an increase in deer killing does not solve the problem of deer-vehicle collisions. In fact, there is also evidence that suggests a direct correlation between higher deer-car accident statistics and the onset of hunting season.17 It has been suggested that hunting season has a disruptive effect by startling deer and putting them more "on the run." Erie Insurance Group even states that the amount of deer-vehicle collisions "rose nearly five times on the first day of buck season and doe season"18 With nonlethal and effective mitigation measures such as driver education, reduced speed limits, improved fencing techniques, lining the roads with vegetation that is unpalatable to deer, and the use of roadside reflectors to deter deer from crossing roads, some communities are actually reducing the number of deer-vehicle collisions rather than relying on the pro-hunting "shoot first, ask questions later" propaganda. Several scientific studies applaud the use of Strieter-Lite Reflectors (formerly called Swareflex Reflectors) that, when installed and maintained properly on the sides of roadways, can reflect light from a vehicle's headlights and stop deer from crossing. For example, the Minnesota Department of Transportation saw a 50-97% decrease in 38 locations across the state in deer-vehicle collisions.19 At least twelve states are now implementing this method in specific locations.20

Q: DOESN'T HUNTING STOP THE SPREAD OF LYME DISEASE?

A: Although deer are a primary carrier of the adult Ixodes scapularis tick -- the "Lyme disease tick" or "black-legged tick," formerly known as Ixodes dammini -- many wildlife species carry the larval and nymph stages of the tick which are the most infectious to humans. The tick can be found on 49 bird species21 and commonly carried by white-footed mice, chipmunks, grey squirrels, voles, foxes, rabbits, and opossums.22 When deer numbers are reduced, ticks tend to congregate at higher densities on the remaining deer23 or switch to alternate hosts.24 Even during a study in which all the deer were eradicated from an island, the number of adult ticks actually increased.25 Lyme disease is easily treatable if it is caught in time, and nearly every state wildlife agency and physician's office offers free brochures on how to protect yourself from Lyme disease ticks.

Q: WHAT ABOUT PEOPLE WHO NEED DEER MEAT TO SURVIVE?

A: While there may be a few native cultures that still hunt for food, the overwhelming majority of American hunters practice the activity only for sport. Several studies indicate that the average price of venison from deer killed in the woods -- after calculating the costs of firearms, ammunition, license fees, travel expenses, etc. -- is about $20.00 per pound.26 Clearly, there are more economical ways to eat than by spending $20.00 per pound for food. Organizations such as "Hunters for the Hungry" are nothing more than public relations outfits that try to convince the public that hunting is beneficial to people. If hunters really cared about homeless or low-income families, they could purchase a lot more food for $20.00 than a pound of deer meat.

Q: WON'T DEER STARVE TO DEATH IF THEY ARE NOT HUNTED?

A: Hunters do not search for starving animals. They either shoot animals at random, or they seek out the strongest and healthiest animals in order to bring home the biggest trophies or largest antlers. In fifteen years, fewer than 4,000 deer starved to death in Vermont, Maine, and Texas combined.27 Clearly, hunting is not stopping starvation, but may in fact be adding to the problem by triggering productivity. Even hunting columnists have condemned "the risk taken to build up the state deer herds to unrealistic levels in order to satisfy hunters and to sell more hunting licenses each year."28

Q: DEER CONTRACEPTION IS NOT REALLY AN OPTION, IS IT?

A: With the vast surge in immunocontraceptive technology over the past few years, the deer contraceptive dart known as porzine zona pellucida (PZP) is a viable option for communities. The contraceptive, when injected into female deer, stops them from reproducing for one to two years. The National Park Service tested PZP on Fire Island National Seashore off the coast of Long Island and reported a 95% success rate.29 The National Institute of Standards and Technology is now using PZP at its 575-acre campus in suburban Maryland resulting in a marked decrease in births due to the vaccine. PZP trials by the Humane Society of the United States have proven 95% successful in blocking pregnancies for one year in white-tailed deer in parts of the United States.30 If wildlife agencies did not spend billions of dollars on hunter education, enforcement of hunting regulations, and other hunting-related activities, that money could be better spent on more immunocontraceptive research.

Q: WHETHER IT'S NATURAL FACTORS OR HUNTERS KILLING DEER, WHAT'S THE DIFFERENCE?

A: When animals die of natural causes such as starvation or predation, the old and the sick animals die, leaving the strong and healthy animals to reproduce and to keep the herd strong. When animals die of starvation, their carcasses become critically important food reservoirs for bears, coyotes, opossums, hawks, owls, and eagles who rely on some winter mortality to make it through long winters. There's no such thing as waste in an ecological system where deer carcasses replenish life-supporting nutrient cycles such as nitrogen. Hunters, however, disrupt this natural system, removing the strongest and healthiest animals from the population and leaving animals who would normally not have reproductive success to pass on their genes. In light of the consequences, it is no wonder some ecologists have referred to hunting as "evolution in reverse."
