Why is Trapping Reform Necessary?
Trapped animals are exposed to the elements, the bitter cold, risk frostbite, dehydration, unable to escape from potential predation, ie. other animals attacking and feeding on them. Trapped animals commonly suffer from mouth injuries and for some, tooth loss, as was the December 2018 case of the little lost dog trapped overnight in Helena. Animals bite at the trap to try to escape. Some eventually bite off or twist off their trapped paw. Trappers call it wring off.
A wolf trapping study was conducted in Minnesota between April and October, with almost all captures occurring when temperatures were above freezing. The trap tested was a leghold trap Livestock Protection Company #4 with smooth offset jaws. 18% of the captured wolves had dental injuries rated as "moderate" to "severe" and the rest were described as uninjured to having "mild" injuries. "Serious leg injuries were relatively common; however, compared with different trap types tested in other studies, 63% were scored as having moderate to severe damage including major cutaneous lacerations, tendon damage, and fractures including some to the radius or ulna."

The Association of Fish & Wildlife Agencies (AFWA) represents North America's fish and wildlife agencies to advance sound, science-based management and conservation of fish and wildlife and their habitats in the public interest.” “The purpose of Association of Fish & Wildlife Agencies (AFWA) Furbearer Management and Best Management Practices for Trapping Program (BMPs) is to improve regulated trapping by evaluating trapping devices and techniques used for the capture of furbearers and educating those who use traps about the most humane, safe, selective, efficient and practical devices. “
Association of Fish and Wildlife Agencies states, “Make a commitment to check your traps at least once every day. When you set out a trapline, you assume responsibilities. Animal welfare is a top priority. Most furbearers are nocturnal so it is best to check your live-restraining traps at first light each morning. If you cannot check them at daylight, check them as early in the day as possible. One important difference between trapping and hunting is your commitment to work your trapline every day until you remove your traps. Hunters can choose the days they want to hunt, but trappers must check their sets every day. Bad weather or other problems should not change your plans. If you cannot personally fulfill your responsibility to wildlife and fellow trappers because of illness have another licensed trapper check your line. “
36 states have 24hr/daily trap checks within their trapping regulations. These include Washington, Colorado, New York, Arizona, Vermont, New Mexico, Minnesota.
The longer an animal is in a trap the greater the damage whether that be to a coyote, a wolf, a mountain lion, a wolverine, an eagle, a lost pet or a working dog.
When the environmental temperature drops below 32° F (0 celsius) blood vessels close to the skin start to narrow and constrict. Frostbite strikes the areas of the body that have the slowest circulation. The death of tissue due to frostbite is actually caused by a lack of blood flow. This is what occurs as an animal lingers in the trap during temperatures below freezing. As frostbitten tissues thaw. they may become red and very painful due to inflammation. The clinical signs of frostbite may take several days to appear. Severely frostbitten areas will become necrotic or die. Animals such as mountain lions highly dependent on those paws have little chance of survival and are believed to eventually succumb to the effects of frostbite after they are released from a trap.
48 mountain lions were reported “accidentally” trapped in a two year time frame 2013-2015 in Montana according to FWP reports. 16 of those were caught in traps set for wolves. 1/3 of those mountain lions in "wolf trap sets" were dead. Recall wolf trap sets require 48 hr check times! 32 mountain lions were caught in traps not set for wolves, ie smaller leghold traps, snares, conibears. 66% were dead! 84% of the reported mountain lions were DEAD OR INJURED! and these are just the ones we know about. 96% were deemed legal trap sets. Over 75% were on public land.
According to the American Medical Veterinary Association, “Limb restraint is likely to cause fear and intermittent collection of animals caught in leg-hold traps means that fear may sometimes be extended as long as 24-hours (with 9 states allowing longer periods). Leghold traps cause injury that sometimes exceeds ISO welfare standards.”
Per the FWP “Non-Target Wildlife Captured in Traps (non-wolf traps)” reports in just 15 months from 10/26/13-1/24/15. Montana trappers reported 63 non-targets, i.e. animals they did not mean to trap. These were not traps set for wolves, either. Among the captures were mountain lions, wolverine, grizzly, great horned owl, deer, black bear, goose, eagle and other raptors. 30% were on private property. Only 1 trap was deemed ILLEGAL. 71% of these 63 non-targeted trapped and reported animals were found DEAD. Trappers DO NOT have to report the non-targets, the accidental captures, if they think the animal is unharmed unless they are in wolf traps.
A condition known as capture myopathy occurs when animals overexert themselves (struggling in a trap for example) so much that physiological imbalances develop and result in severe muscle damage. Capture myopathy may result in sudden death, or clinical signs may develop hours, days, or up to two months following capture in which the animal eventually dies from heart failure. Those that work in wildlife rehabilitation can attest to this.
An average of 55,000 animals are trapped and killed annually in Montana according to FWP. Most of these numbers come from trappers completing a voluntary survey. Less than ½ of the trappers complete the survey. Non-targets, accidental trappings, are not included in the harvest reports. The collateral damage from those animals that eventually escape with the trap still attached, the trap released that still perish, the orphaned young are also unaccounted for.
104 dogs were reported TRAPPED in Montana in less than 30 months, 9/2012 - 2/2015 according to FWP reports. Over half were with their owners. Some pets get killed. Some never get reported. No records are kept of trapped cats. Some pets are lost and found or freed from traps multiple days later. Most incur vet bills that the owners pay. Some trapped pets never make it home.
Scientists and researchers that want the animal alive and uninjured conduct 24 hour trap checks, at minimum. For most, it is every 12 hours including what is practiced by Montana FWP biologists. Many do not trap in the winter in order to avoid frozen paws. Some scientists also put sensors on traps to signal when an animal has been caught, allowing them to respond quickly.
“The longer that animal is in a trap, the more likely you have foot injury, shoulder sprains, vascular damage, neural damage,” said Carter Niemeyer, a retired wildlife biologist who believes traps should be checked daily.
Guidelines from the American Society of Mammalogists state, “Snares or spring foot-hold traps must be checked at suitable frequencies. These observations should be a least daily, but more frequent depending upon target species, the potential for capture of nontarget species, and environmental conditions."
According to the Guidelines from the American Society of Mammalogists, “The number of traps set at a particular time and location should not exceed the ability of the investigator(s) to monitor them at reasonable intervals. Because frequent checking of traps is the most effective means of minimizing mortality or injury to animals in live traps."
