Desert Aerators in Mexico

Where brush has grown into small trees, crushing the growth is a plausible alternative to poison. Aerators can sometimes work where grades or topography make subsoil plowing impractical. Once plants are thinned, aerators might be followed by subsoiling. Smaller is better. Use of contours is essential. Applications must vary since no two properties are the same.

Wild Boar Trappers Fear Hog Poison’s Effect on EU Wild Meat Market

The feral pig ‘problem’ is a regulatory issue.  The one bright spot is that the Europeans – whose food safety standards far exceed our own –  love our free range pork.  The brilliant idea to use Warfarin to control pigs will destroy that market, and produce unknown and unintended consequences to other animals. As for

Meat Production Helps Offset Wild Pig Problem

When properly prepared, the taste of free-range pork is the same as factory pork.

Study Shows Mountain Lions Pose no Human Threat in Big Bend National Park

Studies at Big Bend National Park show that mountain lions avoid humans, are most active early and late in the day, and that female lions are more active than males. This is consistent with our experience and observations at Circle Ranch, where we protect our lions because they and all other predators are necessary for

Antibiotic Use on Farms Helps Fuel Antibiotic-Resistant Diseases

Feral pigs, according to our wildlife and food quality experts, are unfit to eat because they carry diseases. But do they? Over the last 30 years, the two largest processors of wild pigs in Texas have slaughtered and tested tens of thousands of animals. They have never found a diseased pig (don’t confuse parasites with diseases.) Factory farms, on

Slideshow: Circle Ranch Wildlife, December 2016

There is not a federal or state park in far-West Texas where one can see free ranging elk, sheep, pronghorn and mule deer together. These animals and many others are found in abundance at Circle Ranch, because of our (1) water system, (2) periodic planned cattle grazing, (3) protection of predators, (4) protection of all

Attacking Aoudad on Behalf of Bighorn

The Borderlands Research Institute (BRI) and Texas Parks and Wildlife Department (TPWD) say aoudad harm desert mule deer, pronghorn and desert bighorn, and habitat, because they (1) eat plants, (2) drink water and (3) do well. In fact: Aoudad and Bighorn are Complimentary, not Competitive The articles below reflect the institutions’ longstanding but scientifically unproven

Building Soil Fertility by Peter Byck

Physiologically there is no difference between public land and private land. What hurts or benefits one has the same effect on the other. Wildlife managers, whether we work on public or private land, must adopt restoration ecology if we hope to reverse the desertification of American Southwest’s grasslands. This 24-minute video discusses how to best

Screwworm Returns To The United States

The screwworm eradication program—a triumph of animal health science—came with unintended consequences. When the flesh-eating pest was eradicated and big predators were removed, deer numbers exploded. Now more than ever we need to protect deer predators for the health of the deer herds and their habitat, which cattle share with wildlife.

Circle Ranch Game Cameras – Mid Fall 2016

Do most of the species pictured below—and all of the predators—“compete” with each other and harm bighorn, mule deer, pronghorn and ecosystem health as the wildlife agencies say? Or do they complement each other? Is biodiversity good or bad for our deserts? Recent studies of the Serengeti shed light on this debate. They confirm that
