Trapping Facts
Quick Facts About Trapping

There are more wild furbearers in the United States today than there was 100 years ago.
There are no furbearing animals in the United States or Canada which are endangered or threatened by fur harvesting today.
Millions of North Americans depend on fur harvesting for their livelihood. These people have a vested interest in protecting the natural environment.
Nothing is wasted in the production of a wild fur garment. Furbearers provide food, organic fertilizer, medicines, and other biodegradable products.
Conversely, synthetic materials exhaust our limited supply of oil and other non-renewable resources.
Sound wildlife management programs ensure the necessary supply of natural wild fur for today's needs and those of tomorrow
About NTA

The National Trappers Association is committed to defending and promoting the safe and ethical harvest of furbearing mammals and to the preservation and enhancement of their habitats.
Fifty-one state trapping affiliates make up the core of the national organization representing thousands of fur harvesters from every portion of the country. The National Trappers Association and its members continue to research and encourage the development and usage of the most effective and humane trapping techniques available.
Furbearers, like other managed wildlife species, thrive and are far more diverse today then 100 years ago. The reintroduction of the river otter throughout America’s river systems is just one example of the successful partnership between trappers and wildlife managers.
The National Trappers Association continues to defend our American Heritage and the sound management of all wildlife for the future enjoyment and use by all sportsmen of North America.
We thank all members and organizations for their dedicated support.

HSUS Statement #1

Trapped animals can suffer from thirst and starvation; they may die as a result of exposure to the elements or predation. (Humane Society of the United States)

Factual Rebuttal: DNR regulation stipulates that traps set in uplands and non-tidal wetlands must be checked once per calender day. This frequency prevents or severely limits the probability of these occurrences. Any person that would violate this regulation would also violate trap prohibition regulations.
The fundamental economic realities of commercial trapping also discourages these occurrences. The margin of profit in commercial trapping is relatively small. Every consecutive day that an animal is in a trap, that trap is non-functional and cannot capture additional animals. In effect, if a trapper allowed this to occur they would be jeopardizing potential revenue.

HSUS Statement #2

The steel-jawed foothold trap has been declared "inhumane" by the American Veterinary Medical Association, the World Veterinary Association, and the American Animal Hospital Association. (Humane Society of the United States)

Factual Rebuttal: These organizations characteristically represent domestic small animal health care providers. The very nature of their professions predetermines that they typically examine only worse case scenarios involving trapped animals. It can be logically assumed that few examinations would be requested for un-injured animals captured in foothold traps.
Animal health care professionals that specialize in wildlife health issues clearly support trapping and the use of foothold traps to manage health concerns in free-ranging wildlife populations.

HSUS Statement #3

Animals still alive when the trapper checks the trapline are killed by bludgeoning or stomping or, less often, by strangulation or shooting. (Humane Society of the United States)

Factual Rebuttal: Portions of this statement reinforce the inherent value of foothold traps. foothold traps are live-restraining devices and the animals are "still alive", thus affording the opportunity to release or harvest captured animals. Although not aesthetically pleasing, blunt force trauma (bludgeoning) and shooting are recognized as humane euthanasia techniques by the American Veterinary Medical Association. Trapper education provides information on humane techniques to put an animal down
Raccoon Roundworms

Raccoon Roundworms

Baylisascaris, an intestinal raccoon roundworm, can infect a variety of other animals, including humans. The worms develop to maturity in the raccoon intestine, where they produce millions of eggs that are passed in the feces. Released eggs take 2-4 weeks to become infective to other animals and humans. The eggs are resistant to most environmental conditions and with adequate moisture, can survive for years.

People become infected when they accidentally ingest infective eggs in soil, water, or on objects that have been contaminated with raccoon feces.

When humans ingest these eggs, they hatch into larvae in the person's intestine and travel throughout the body, affecting the organs and muscles.

Anyone who is exposed to environments where raccoons live is potentially at risk. Young children or developmentally disabled persons are at highest risk for infection when they spend time outdoors and may put contaminated fingers, soil, or objects into their mouths. Hunters, trappers, taxidermists, and wildlife handlers may also be at increased risk if they have contact with raccoons or raccoon habitats.

Infected raccoons have been found throughout the United States, mainly in the Midwest, Northeast, middle Atlantic, and West coast. Infection rarely causes symptoms in raccoons. Predator animals, including dogs, may also become infected by eating a smaller animal that has been infected with Baylisascaris.

Raccoon Roundworms Signs & Symptoms - Nausea, tiredness, liver enlargement, loss of coordination, lack of attention to people and surroundings, loss of muscle control, blindness, coma.

HSUS Statement #4

Body-gripping traps (steel-jawed foothold traps, snares, and Conibear traps) cause severe distress, fear, and pain to both wildlife and pets. Body-gripping traps slam closed on and grip tightly an animal's leg or other body part. As a result, animals can suffer lacerations, broken bones, and joint dislocation. As the animal struggles to get free, he/she sometimes chews off a leg to escape or breaks teeth by biting the metal trap. (Humane Society of the United States)

Factual Rebuttal: The correct terminology and classification of trap types includes 3 different categories. The first category is 'live-capture restraining devices' that allow the release or harvest of trapped animals. foothold traps are included in this category. The second category is 'killing' devices that result in a near instantaneous death for trapped animals. This category includes Conibears and other brands of body-gripping traps. The third category includes traps that can function either as 'live-capture restraining devices' or 'killing' devices dependent on how and where they are set. Snares are included in this category.
Since Conibears and other body gripping "killer' traps are designed to provide a near instantaneous death via force applied directly below the base of the skull, the likelihood of extraneous injury, and/or self mutilation is extremely low. When snares are used as a 'live- capture restraining device they function in a similar manner to a dog collar and leash. Therefore, the likelihood of extraneous damage and/or self mutilation is also extremely low. Highly structured and replicated studies have repeatedly shown that foothold traps are the only efficient, practical, selective, humane, and environmentally benign 'live-capture restraining device' currently available for many furbearer species.
By design, capture devices used to reintroduce extirpated species or augment Threatened and Endangered populations have to ensure minimal damage probabilities to target animals. foothold traps have been used almost exclusively to capture and re-establish red wolves, gray wolves, mexican wolves, lynx, and river otter.

HSUS Statement #5

Body-gripping traps are indiscriminate. They victimize any animal unfortunate enough to trigger them. Animals caught include protected species such as eagles, kit foxes, fishers, and wolverines, as well as family pets. The majority of smaller animals (birds, rabbits, squirrels, etc.) unintentionally caught in traps die or must be destroyed because of serious, disabling injuries. (Humane Society of the United States)

Factual Rebuttal: The selectivity of foothold traps has been documented in studies conducted by the International Association of Fish and Wildlife Agencies in 21 states. The capture of thousands of furbearers resulted in non- target capture rates as small as 3% of total captures, and included no threatened and endangered species. foothold traps are live-capture restraining devices that experience minimal injury rates, and allow release of captured animals. Over 4,000 river otter captured predominately in foothold traps have been released in reintroduction projects in 18 states.
Traps pose no realistic threat to human safety. An exhaustive investigation of trapping incidents in the U.S. during the last twenty years could only document 3 cases of injury to the public that resulted from regulated trapping. All of these injuries were considered minor.

HSUS Statement #6

Commercial trapping is not a "wildlife management tool". There are no bag limits and no limits on the number of traps that can be set. Trapping activity is driven by the price of pelts, not by the need to manage wildlife populations. Some fur-bearers (coyotes for instance) have natural fertility and breeding controls when not disturbed by humans, while others (such as muskrats) experience natural boom-and-bust cycles. (Humane Society of the United States)

Factual Rebuttal: The professional wildlife conservation community universally endorses traps and trapping as critical and essential wildlife management tools. The Wildlife Society and the International Association Of Fish and Wildlife Agencies are the largest international organizations representing professional wildlife conservation employees and governmental wildlife agencies. Both organizations have issued policy statements that strongly support the role commercial trapping plays in achieving wildlife management objectives.
Harvest season length, bag limits, permissible size and types of traps, and total number of traps permissible per trapper, are all considered during the development of management strategies for individual species. Population growth characteristics of some species require strict harvest regulations that include bag limits and limiting the number of traps per individual. Conversely, harvest and population characteristics of other species require liberal regulations to meet prescribed furbearer management objectives.
All wildlife populations possess inherent bio-feedback mechanisms that eventually limit population densities. Most species can exhibit classic 'boom and bust cycles'. The reproductive capabilities of coyotes, muskrats and many other furbearers allow non-regulated populations to increase at exponential rates until they approach and/or surpass the carrying capacity of their respective ecosystems (boom). When this occurs, competition for limited resources compromises the health of the entire population. At that time, the weakened condition of these animals allow density-dependent mortality factors such as starvation, disease, and social strife, to decimate entire populations (bust). Oftentimes, the health of the entire ecosystem including all aligned wildlife species and the public are also negatively impacted by these inflated furbearer populations.
Regulated commercial trapping manages populations by moderating the extremes of 'boom and bust' cycles. This results in stable populations of healthy animals that are in balance with the biological carrying capacity of their ecosystems and the cultural carrying capacity accepted by the general public.

Beaver Fever (Giardiasis)

Giardiasis (GEE-are-DYE-uh-sis) is a diarrheal illness caused by a one-celled, microscopic parasite, Giardia intestinalis (also known as Giardia lamblia). Once an animal or person has been infected with Giardia intestinalis, the parasite lives in the intestine and is passed in the stool. Because the parasite is protected by an outer shell, it can survive outside the body and in the environment for long periods of time.

During the past 2 decades, Giardiainfection has become recognized as one of the most common causes of waterborne disease (found in both drinking and recreational water) in humans in the United States . Giardia are found worldwide and within every region of the United States.

The Giardia parasite lives in the intestine of infected humans or animals. Millions of germs can be released in a bowel movement from an infected human or animal. Giardia is found in soil, food, water, or surfaces that have been contaminated with the feces from infected humans or animals. You can become infected after accidentally swallowing the parasite.

Beaver Fever Signs & Symptoms - Diarrhea, gas, greasy stools, stomach or abdominal cramps, upset stomach or nausea/vomiting, dehydration.

Furbearer

What is a Furbearer?

Technically, the term furbearer includes all mammals, all of which, by definition possess some form of hair. Typically, however, wildlife managers use the term to identify mammal species that have traditionally been trapped or hunted for their fur. Furbearers are a diverse group, including both carnivores (meat eating predators) and rodents (gnawing mammals). Most are adaptable species ranging over large geographic areas. A few animals that are normally hunted or trapped primarily for their meat or to reduce agricultural or property damage may also be considered furbearers if their skins are marketed.
Fur

Fur Facts

Most furbearers possess two layers of fur: a dense, soft underfur that provides insulation and water-repellent qualities; and an outer layer of longer, glossy guardhairs that grow through the underfur, protecting it from matting and abrasion. A fur is said to be prime when the guardhairs are at their maximum length and the underfur is at its maximum thickness. Fur generally becomes prime in midwinter when the coat is fresh and fully grown; the timing for primeness may vary somewhat depending on species, location (latitude) and elevation.
Fur Industry

Fur Industry

Furs are generally tanned, trimmed, and sewn into garments, rugs, blankets and ornaments, and sometimes dyed in a variety of colors and patterns. Furs are also used in fishing lures, fine brushes and other products. Some furs are shaved, and the hair processed into felt for hats and other garments.
The fur trade is tightly regulated by state, national and international governing bodies. These regulations cover everything from animal welfare to environmental impact.
Renewable Fur

Renewable Resource

Fur is a renewable resource (naturally replenished), a product of long traditional use, valued by many for its beauty, durability, insulative and natural qualities. Fur is only one of many values that people ascribe to furbearers. People have continuously used furbearers in North America for clothing, food and religious ceremonies for the past 11,000 years.
The sustainable use of renewable natural resources is based on the fact that most species of plants and animals produce more young than their habitat can support to maturity.

Leptospirosis

Leptospirosis

Leptospirosis is a bacterial disease that affects humans and animals. It is caused by bacteria of the genus Leptospira. In humans it causes a wide range of symptoms, and some infected persons may have no symptoms at all. Symptoms of leptospirosis include high fever, severe headache, chills, muscle aches, and vomiting, and may include jaundice (yellow skin and eyes), red eyes, abdominal pain, diarrhea, or a rash. If the disease is not treated, the patient could develop kidney damage, meningitis (inflammation of the membrane around the brain and spinal cord), liver failure, and respiratory distress. In rare cases death occurs.

Many of these symptoms can be mistaken for other diseases. Leptospirosis is confirmed by laboratory testing of a blood or urine sample. Outbreaks of leptospirosis are usually caused by exposure to water contaminated with the urine of infected animals. Many different kinds of animals carry the bacterium; they may become sick but sometimes have no symptoms. Leptospira organisms have been found in cattle, pigs, horses, dogs, rodents, and wild animals. Humans become infected through contact with water, food, or soil containing urine from these infected animals. This may happen by swallowing contaminated food or water or through skin contact, especially with mucosal surfaces, such as the eyes or nose, or with broken skin. The disease is not known to be spread from person to person.

Leptospirosis Signs & Symptoms - High fever, headache, chills, muscle aches, vomiting, jaundice, red eyes, abdominal pain, diarrhea, rash.

Rabies

Rabies is a disease caused by the rabies virus. It may take several weeks or even a few years for people to show symptoms after getting infected with rabies, but usually people start to show signs of the disease 1 to 3 months after the virus infects them. The early signs of rabies can be fever or headache, but this changes quickly to nervous system signs, such as confusion, sleepiness, or agitation. Once someone with rabies infection starts having these symptoms, that person usually does not survive. This is why it is very important to talk to your doctor or health care provider right away if any animal bites you, especially a wild animal.

Many kinds of animal can pass rabies to people. Wild animals are much more likely to carry rabies, especially raccoons, skunks, bats, foxes, and coyotes. However, dogs, cats, cattle (cows), or any warm-blooded animal can pass rabies to people. People usually get rabies from the bite of an infected animal. Many animals, such as dogs, cats, and horses are vaccinated against rabies, but you should always wash any bite thoroughly and check with your health care provider about what to do if any animal bites you.

Early Rabies Signs & Symptoms - Similar to flu, discomfort, fever, headache. Don't delay calling the doctor!

Modern foothold traps (these are the same traps used by public trappers) have been used to successfully capture river otter and release them unharmed into other areas of the United States to restore otter populations.

Capture and Relocate
Lynx reintroduced to some western states were captured by foothold traps in the Yukon, Canada.
Red wolves, Mexican wolves and Grey wolves were captured by foothold traps, examined and relocated to establish new populations. Some are used for captive breeding programs by wildlife officials.
Tick Borne Illness

Tick Borne Illness

Ticks may transmit several different diseases to humans, including Lyme Disease, Southern Tick-Associated Rash, Rocky Mountain Spotted Fever and more.

Lyme disease is spread by the tiny deer tick. Ticks feed on blood, and infected ticks transmit the disease as they feed. Although the deer tick prefers to feed on wild animals, especially mice, birds, opossum, raccoon, and deer, they will also feed on dogs, cats, livestock, and humans. When people visit or live near deer tick habitats, they run a high risk of contracting Lyme disease. For your own safety, you should become familiar with tick habits and habitats, and you should learn how to prevent tick bites.

Tick Borne Illness Signs & Symptoms - Fever, chills, aches and pains, rash.

About the Beaver

Castor Canadensis
Order - Rodentia
Family - Castoridae
The beaver is the largest North American rodent. A common furbearer, the beaver inhabits waterways of every North American state and Canadian Province. A unique paddle shaped tail distinguishes the species and self-sharpening teeth allow beavers to mow down sizable trees. Beaver often alter the landscape with the construction of dams, canals and lodges. Beaver are territorial as long as the habitat will support family groups called "colonies". Beaver are powerful animals both on land and in the water.

Beaver Fast Facts

• Adult beaver can weigh over 70 pounds

• Beaver have 4 teeth

• Mating season is late January and February and gestation is 107 days with 3 to 5 kits born in litter

• Beaver can hold their breath up to 15 minutes and kits can swim within hours of birth.

• Beaver can live up to 12 years

Description

Beaver continue to grow in size throughout life, and weights in excess of 60 or 70 pounds do occur when foods are abundant and accessible during the entire year. Unlike many other species, females are as large as males of the same age, and they sometimes are larger. A paddle shaped, leathery tail, positively identifies the species. An adult's tail is usually about 10 inches long, and 5 or 6 inches wide, with a thickness of 1/2 inch in the middle.
The hind feet of beaver are fully webbed, and large. These feet often measure 6 inches in length, and the spread of the toes is equal to or greater than the length as the beaver swims. Five toes with strong nails are found on the hind feet, including unique split toenail on one toe which serves the beaver as a comb for grooming. The front feet seem small in contrast to the hind feet. These feet measure 2 1/2 to 3 inches in length and are not webbed at all. Beaver normally swim with their front feet held against their chest, and the large webbed hind feet provide the propulsion with the tail acting as a rudder.
Guard hairs in beaver fur are 2 inches in length, overlaying a soft and dense underfur about an inch deep. Colors vary from section to section, and from blonde colors to nearly black. Both male and female beaver have large glands, called castors, beneath the skin on the lower bellies. These glands produce an oil which the beaver combs into its fur to waterproof it. This oil is also deposited by the beaver at selected locations as territorial markers or mating attractants in the spring of the year.
Beaver have transparent eyelids which cover the eyes as the beaver submerges, enabling the beaver to see well when submerged as the eyeball is protected from abrasive particles suspended in the water. The ears and nose of a beaver have valves that close as a beaver submerges, preventing the entry of water. Two upper and two lower incisor teeth dominate the front of a beaver's mouth. The upper incisors overlap the lower incisors, and friction from chewing causes the teeth to self-sharpen to chisel sharpness.
Similar to birds and reptiles, beaver have a single lower body opening, known as a cloaca. This single opening serves the urinary and bowel tracts, the secreted oil from the castor glands, and covers the reproductive organs of both males and females.

Beaver Habits

Beaver require deep water for protection from their enemies, and they alter the landscape a great deal with dam building and flooding. Dams can be hundreds of feet in length, and vary in height from only a few feet to 7 or 8 feet, and even higher at times.
Permanent lodges are often constructed by piling layer after layer of sticks into a large conical form above the waterline. Two or more underwater tunnels are then chewed up into the pile, and an inner chamber hollowed out to serve as a living quarters. Finally the outside of the lodge is plastered with mud and rocks, except for the peak, which is left porous enough to allow an air exchange to the inner chamber. There are two levels to the chamber. One level is near the waterline near the "plunge holes", where the beaver shed water before climbing to the higher resting or nesting areas.
In areas prone to flooding, or where strong currents may be present, beaver usually construct bank dens by digging tunnels from underwater up into banks. Bank dens often have two or more submerged entrances. Many times the beaver will construct a pile of sticks over the tops of the underground living chambers. These piles of sticks are sometimes called "caps".
Shallow pockets are sometimes dug into banks near the waterline and these are known as "feed pockets". In northern areas, beaver construct "feed piles" by submerging large amounts of small trees and limbs to serve as a food source after ice prevents the beaver from activity above the ice. These feed piles are usually constructed close to the den as a convenience to the kit beaver, who do not normally travel far from the den itself.
At times, solitary beaver will be found living alone. These beaver are known as "bachelors", whether they are male or fernale.
Adult beaver mark out their territories in early spring by dragging up mud and debris from the bottom and depositing the debris in mounds along the shores, where they also deposit oil from their castor glands. These "castor mounds" often leave a reddish stain on the bank, and the odors are powerful enough for a human to easily detect.
Beaver are very territorial, and territories seldom overlap. Generations of beaver may continuously inhabit a choice area, even building canals to help float food from inland cutting sites. If and when food supplies are exhausted, they do relocate to better area. Once beaver have determined to claim a territory, they are very difficult to dissuade. If the activities of the beaver flood roads or damage property, the beaver usually have to be removed to prevent reoccurring damages.
Although beaver normally submerge for 3 or 4 minutes at a time, they are quite capable of holding their breath for 12 to 15 minutes. They exhale a little in spurts as they swim or work under water, and a large beaver is quite capable of traveling nearly 1/2 mile under the surface before it must surface for more air.
Migrations of beaver usually occur with the breaking up of ice in late winter or early spring as the 22 or 23 months old beaver are expelled just prior to birthing time for the new litter. These beaver may chose to go up or downstream. Although these beaver are capable of reproducing, they usually do not until the next season, after a mate and a new territory have been established. Most new colonies are established within a few miles of the home colony.
Beaver are primarily vegetarians although an occasional beaver may eat a dead fish. Preferred foods include the bark of aspen, willow, cottonwood, and dogwood, and many other varieties of trees and shrubs. In early spring, beaver will often eat bark and twigs of evergreens. In season, beaver will also eat water lillies, leaves, grassses, roots, and a variety of crops including corn, wheat, oats, carrots, potatoes, apples, clovers, and alfalfa.

General

Beaver usually alter the habitat a great deal with the building of dams, and the resulting flooding of lowlands. The deeper water behind dams creates a better habitat for muskrats, and a variety of other wildlife species such as fish and waterfowl. Mink and otter hunt regularly around beaver dams. These locations provide suitable denning sites as well for these furbearers.
Dam building on trout streams can have an adverse effect on trout survival by slowing the water and allowing it to warm to temperatures higher than the trout can tolerate. Dams also serve as barriers to migrating trout and salmon. At times, beaver cause significant amount of property damage by cutting trees, and flooding large areas also killing the timber. Culvert plugging is common, and often causes roads to flood and to wash out,
Beaver are also host to an internal parasite, giardiasis. Water reservoirs inhabited by beaver can and do become contaminated by the giardiasis cysts, which are too small to be filtered out of the drinikng water. These cysts hatch in the small intestines of people who drink the contaminated water resulting in diarrhea, nausea, and stomach aches.
Serious beaver predators include mountain lions, wolves, lynx and bobcats. At times, a bear can and will kill mature beaver. Juvenile beaver are vulnerable to coyotes, eagles, and large owls as well. Tularemia can be a devastating disease in beaver, wiping out entire populations when conditions are good for disease transmissions. Tularemia infects livers, and is usually fatal to beaver of all ages.
A beaver is considered to be old at 12 years of age.
Young Beaver

Beaver Reproduction

Beaver usually live in family units consisting of the older mated pairs, young from the previous year, and young from the current season called kits. Breeding season takes place in late January or February in most states. Young from the previous year are about 22 months of age at this time and they are evicted from the colony to relocate and seek mates of their own. The gestation period of beaver is 107 days and the adult male and kits usually take up a temporary residence in a bank den while the new litter is being born in April, May or June. The birthing process may take several days, and 3 to 5 kits are a typical litter size. Beaver kits are fully furred when born, their eyes are open, and the incisor teeth are visable. Newborn beaver kits take to the water easily, and they might be swimming before they are one day old. Most adult beaver are monogamous, and stay with their mate throughout life.
