Holistic Planned Grazing on Rangelands: Why the Gap Between Researcher Beliefs and Rancher Experience?

In this paper published in the Journal of Environmental Management, Texas A&M range scientists and their colleagues discuss why—70 years after the development of holistic planned grazing, and notwithstanding the positive experience reported by so many producers who use it—academicians and researchers remain closed to its concepts.  

Allan Savory and the Science of Tracking

“Over the last 60-years, Allan Savory has at different times worn a wildlife agency shirt & crest, his country’s military battle camouflage, the formal attire of a parliamentarian, and rancher’s dungarees. His in-the-bush and on-the-ground observations gave rise to the physiological insights of holistic grazing and wildlife management; his guerrilla warfare and parliamentary experience informed

Hunting Moose in Canada to Save Caribou From Wolves

Wildlife interactions are often counterintuitive. When we oversimplify these unimaginably complex systems we do things that inadvertently damage wildlife and its habitat.

Planned Grazing and Deer

“Properly grazed cattle can improve deer health. Cattle herds can replace the big nomadic grazers with which animals and plants evolved. Plants and animals are symbiotic: Plants need animals as much as animals need plants. What helps plants helps all animals. Biodiversity of plants and animals is good. Multiple species are generally complimentary not competitive.

Circle Ranch Wildlife Cameras – Summer 2017

Every month we review 5,000 pictures and post a few of the most interesting. What is pictured here is biodiversity. Multiple species are complimentary – not competitive. Ranges need keystone grazers like bison or cattle, lots of predators and lots of prey species. Without all these, the systems come apart. Our habitat is in excellent condition and

Are Wolves the Pronghorn’s Best Friend?

Let’s look for a holistic solution to pronghorn decline in far-West Texas. As discussed in the article below, pronghorn fawn survival triples when wolves are present because wolves control the coyotes which otherwise kill the pronghorn fawns. Cattle removals, predator removals and so-called invasive species removals have drastically altered the wild population equation, throwing the system

Desert Mule Deer “Management”: Does Culling Low-Point Desert Mule Deer Bucks Help or Harm the Herd and Its Genetics?

Culling Mule Deer – or whitetail – is scientifically unjustifiable, and does not improve herd genetics. Note: This post originally appeared on this blog in November 2014 Approach #1: Remove Cull Bucks to Improve Herd Genetics …Jerad Wayne Zachary, Deer Guide Dear Mr. Gill, I hope you are doing well. I just wanted to throw in

California Condor Takes Flight in Wild After Near Extinction

The condor “once patrolled the sky from Mexico to British Columbia,” including far-West Texas. Perhaps someday soon they will again. While the majestic sight of a condor in flight makes it obvious why we should support national efforts to save endangered species, it is equally important to save less charismatic species because the web of

Richard Teague et al. on Benefits of Planned Grazing

Here is peer reviewed, hard science from Texas A&M on the topic of holistic planned grazing. This paper by Texas A&M range scientists Richard Teague, Fred Provenza et al. studied the benefits of concentrated, rapidly moving cattle herds on rangeland health. Their peer-reviewed findings contradicted the earlier conclusions of other Texas A&M researchers David Briske

Rare Big Bend Grass Added to Federal Endangered Species List

Most agencies, universities and conservationists continue to blame cattle grazing for grassland decline. The biodiversity loss described in this article is real but the blame is misplaced. The real cause of grassland decline is lack of animal impact from periodic grazing of bison or cattle and abundant wild species. The finely balanced system also requires
