The Making of a Mexico-to-Canada Wolf Corridor
Part 1: Mexican wolves can devastate a ranch economically in ways not readily apparent or understood by the public

- Keeping the Mexican gray wolf (Canis lupus baileyi) on the endangered list as a subspecies. A conundrum. The Mexican wolf is a gray wolf that breeds with other gray wolves and is not a subspecies. A grizzly and a black bear are subspecies.
- Issuing permits to private landowners to kill wolves killing livestock on their property based on the number of Mexican gray wolves that exist in the wild, not immediate or continuing wolf depredations.
- Handling Mexican wolves killing livestock on private lands are not included in the USFWS's new 'problem' wolf proposals. Mexican wolves killing livestock on private land are problem wolves.
- When wolf depredations occur on private property, the number of animals killed have been reported in the past. The USFWS intends to replace the term "depredation" with the term "depredation incident." A "depredation incident" is defined as ". . . the aggregate number of livestock killed or mortally wounded by an individual Mexican gray wolf or pack at a single location within one 24-hour period." Under this definition, wolves can wipe out a herd like the 176 head of the Siddoway Sheep Company's sheep that died on the west slope of the Tetons in Idaho when a pack panicked them off a ridgeline and they were trampled or suffocated.
Expanding the Mexican gray wolf's Arizona-New Mexico "experimental population area boundary" south past IH-10 in New Mexico and Arizona to the Mexican border and east to the Texas state line in West Texas and up along the Panhandle border, west to the Nevada state line, and north towards Utah and Colorado. This expansion will allow the Mexican wolves to roam areas void of enough wildlife to feed them. Southern and southeastern New Mexico that borders Texas is at least a third dry land farms that disc, plant, cultivate, harvest, and graze year-round with little past or present predation on livestock and pets other than an occasional coyote. And because federal land boundaries have no meaning for Mexican wolves, the possibility of them drifting south and east out of southern New Mexico, and north out of Mexico, is high.
Dumped in the middle of America's world class wildlife herds, they reproduced rapidly, expanded their territories, and decimated Yellowstone's and the surrounding area's big game herds. The Park's traditional moose herd of 1,000 is gone and its elk herd that historically averaged 19,000 is at 3,000 (+) and declining, as are mule deer, mountain sheep, and mountain goats.
From Idaho and Montana, these Canadian wolves spilled outward into adjacent states like Washington, Oregon, and northern California, and south towards Colorado, Utah, Arizona, and northern New Mexico wreaking havoc on western wildlife and livestock and virtually destroying the western states' multi-billion dollar a year hunting industry.
In 1998 captive Mexican gray wolves were reintroduced in Arizona by the USFWS. Shortly thereafter they spread into New Mexico. Over the next decade the USFWS trans-located several more pen-raised packs into New Mexico's sparsely populated 558,065-acre Gila Wilderness. These releases included wolves with confirmed depredations in Arizona that, upon release, continued killing livestock on New Mexico ranches.
Jess Carey, Catron County Wildlife Investigator, documented how these Mexican wolves affected his community, Reserve, New Mexico, and the surrounding ranches over the next decade.4 Among his observations were that habituated Mexican wolves released deep inside the Gila Wilderness didn't stay long; choosing instead to migrate to human activity--ranches, homes, communities. He found that habituated wolves:
- Seek out humans and human use areas,
- Don't use or want ideal habitat unless it includes homes, communities, and people, and
- Teach off-spring (by their actions) to become habituated.
- Wolves often consume the whole carcass--especially calves--including skull, hooves, bones, and hair.
- What the wolves don't eat, Coyotes and other scavengers wait on the periphery to finish once the wolves leave.
- Livestock killed in rough or remote terrain can go days without discovery.
- Hot weather decomposes carcasses fast.
- Measurable canine spreads with corresponding hemorrhage
- Massive hemorrhage in the muscle tissue
- Large bones broken
- Measurable compression canine spreads
- Blood trail
- Ground disturbance
- Uprooted/torn/tramped vegetation
- Wolf tracks
- Wolf scat
- Attack site
- Feeding site
- Drag marks
- Ground and aerial telemetry documenting wolves at the scene or in the area and/or
- Other confirmed livestock depredations in the immediate area
- Wolf-caused chronic stress in cattle leads to loss of body condition, cows birthing weak calves, pre-mature birth of calves, abortion of calves, immune suppression, decreased pregnancy rates and open cows, increased susceptibility to disease, major weight losses, plus altered demeanor of cows from docile to aggressive after wolf attacks and encounters that make them difficult or dangerous to handle to the point they have to be shipped.
- Maimed or deformed cattle that survive a wolf attack are greatly devalued by the market.
- Revenue lost from long-term productivity of uncompensated wolf kills puts serious financial burdens on ranchers.

W. R. McAfee is the author of The Cattlemen and Plugger, and is at work on his third book, West of the Cities, a collection of short works about rural America. McAfee has worked as a reporter and editor for daily newspapers, and has written numerous magazine articles. A Passing Hand, first published in 1975, was selected as one of the three best short works that year by the Western Writers of America. Between 2000-2004 he completed a series of articles on how the EPA, Endangered Species Act and related legislation was devaluing farm and ranch land; often forcing farmers and ranchers off their property.
