Desert Restoration: Aoudad, Mule Deer and Summer Rain

These short videos were taken in August 2014 at “Sheep Tank,” which is on the south edge of the Circle Ranch, at an elevation of approximately 5,500 feet. Sheep Tank is in a long, broad valley, which is approximately 1,000 feet higher than our lowest desert, and 1,000 feet lower than our highest mountain country.

High-Desert Restoration Technicians: June 2014

Bighorn and aoudad play an indispensable role in maintaining healthy habitat in the extreme upper elevations of our far-West Texas mountains. Contrary to game manager ‘urban legend’, these animals are socially compatible, and improve habitat conditions for one another. Here are cool videos of bighorn and aoudad sharing water, taken in the summer of 2014.

Desert Grassland Restoration Crew at Work: June 2014

This blog was established to promote the use of sound science in our wildlife and habitat management practices. We devote a lot of time to talking about the role of cattle delivering the animal impact which grasslands require. In fact, most of our animal impact comes from the wild animals in these pictures. Each has

Restoring Desert Grasslands: Yeomans Keyline Subsoiling Results at the Circle Ranch, August 2014

Here is a cheap, fast, environmentally-friendly alternative to range poisoning with herbicides. When combined with holistic planned grazing of cattle, and a diverse population of wild animals, this practice leads to rapid conversion of subsoil to topsoil, increases soil fertility,  improves and restores water function, and, is sustainable.

Restoring Desert Grasslands with Livestock

Last week we posted a brief explanation of Keyline theory.  This week, we share a concise explanation of holistic planned grazing, which uses animal impact to restore grasslands.   By Carol Dreibelbis In this series, we interview inspiring people that our readers have nominated. These individuals are working on the front lines to improve the

Virus Plagues the Pork Industry, and Environmentalists

The major killers of humanity throughout our recent history: smallpox, flu, tuberculosis, malaria, plague, measles and cholera, are infectious diseases that evolved from animal diseases. Because humans lived in close proximity to these confined animals, their diseases transferred to humans. Mad Cow Disease probably transferred to humans because cattle offal, including brain tissue of infected

Planned Grazing Restoring Chihuahuan Desert Grasslands in Mexico

As you travel south from far West Texas, crossing the Rio Grande, you encounter the huge grasslands of the Northern Mexico area of the Great Chihuahuan Desert. This country is very similar to the Circle Ranch, and has experienced the same degradation from human impact that we see across the desert Southwest. This beautifully photographed

Invasive Species Eradications: "The Rest of the Story"

If you have bought into Big Wildlife’s ‘invasive species crisis,’ and believe that eradicating and poisoning of  ‘invasive’ species of plants and wild animals are based on science, or benefit ecosystems including wildlife and habitat, you need to hear “The Rest of the Story.”

Circle Ranch Game Cameras: May 2014

“Competition” or Cooperation?   Here are links to some great pictures of many species sharing water and habitat at the Circle Ranch. Several of the species photographed such as the aoudad and bighorn pictured above,  are said by game ‘managers’ to be incompatible. ‘Exotics’, these ‘experts’ say, harm bighorn, deer, pronghorn, and others. Our observations,
