In 2008, she said, the Fish and Wildlife Service and other planning agencies chose to leave all the problem wolves on the ground.
“They weren’t meeting the numbers they thought they should be meeting,” Schneberger explained. “They stopped entirely managing for human needs other than the Mexican Wolf Foundation’s efforts to do some flattery and possibly pay for some range riders in a few areas.”
This change in management has resulted in the rise of illegal shootings this past year, she said.
collected over 3000 samples of wolf scat and tested them for undigested evidence of the animals’ prey, such as hair, bones, hooves or teeth.
Using this information, supplemented by the findings of the remains of prey, it was possible for the Görlitz zoologists to determine the nutritional intake of the carnivores in detail. Wild ungulates accounted for over 96% of the wolves’ prey, according to the investigation. The majority of these were roe deer (55.3%), followed by red deer (20.8%) and wild boar (17.7%). A small proportion of the prey was accounted for by the hare, at almost 3 percent.
Cattle Depredation:
Although small in comparison to all available livestock present, depredation is measurable and usually focused on one or two allotments at any given time.
If a depredation is found, ranchers can be reimbursed by Defenders of Wildlife (DOW).
Compensation programs for depredations not found are being discussed.
To date, there have been about 70 possible or confirmed depredations or injuries, with $34,000 paid out by DOW.
Mexican Wolf Diet
Estimated diet of wolves in the Blue Range Wolf Recovery Area based on diet analysis. Intensive monitoring shows that elk are the most common prey.
Elk: 75%
Small Mammals/Unknown: 11%
Deer: 10%
Livestock: 4%

Since the 1800s managed grasslands and shrublands of the arid American Southwest have been grazed predominantly by cattle originally bred for temperate climates in northern Europe. A heritage breed, the criollo cattle, has survived in northern Mexico for more than 400 years under desert-like conditions of low and variable rainfall, hot temperatures in the growing season, and both spatially and temporally scarce levels of primary production. We tested the hypothesis that the heritage breed has a broader spatial foraging distribution under harsh environmental conditions, and that its distribution is driven by environmental variables which differ from those that control the distribution of the introduced European breed. Movements of individual criollo and Angus breed animals were monitored autonomously in the northern Chihuahuan desert of southern New Mexico, USA. Georeferenced foraging locations acquired at 5-minute intervals for each animal ...
many state agency wolf management plans specifically call for compensation to livestock producers—but without any requirements that livestock husbandry practices be in place to reduce or eliminate predation opportunity.
(Defenders of Wildlife has compensated ranchers with $145,000 for 211 "depredations.")
Susan Venus, who runs the Red Hen Café, said she nearly hit a wolf with her car last Friday. It was carrying a cat head, she said.
Frozen in her headlights, it dropped the head on Mineral Creek Road and ran up a hill. Venus retrieved the cat head and put it in a freezer, safekeeping it for evidence.
