Iowa State Fair Cow and Boy Taking Nap Wins the Internet After Photo Goes Viral

This touching photo evokes the ancient connection between humans and livestock. Sadly, modern industrial agriculture – including much dairy and meat production – breaks this connection and increasingly disregards humane animal husbandry.

To Fight Climate Change, Heal the Ground

Soil health and soil fertility should be the goal of every farmer and rancher. Imagine the changes in habitat and wildlife practices if every action and every inaction – such as using fertilizers and pesticides, or removing animals – were tested according to how that action would affect soil health and fertility.

Gone With the Wind - Russian Thistle

Thistle is a great rescue plant for desertified ranges. Quail love thistle seeds and the bugs it hosts, and many wild and domestic animals use it when it is young and tender. NOTE: This article appeared in the June 2017 edition of Texas Wildlife Magazine. The article is posted with

Allan Savory: How to Green the World's Deserts and Reverse Climate Change

Desertification is a fancy word for land that is turning to desert,” begins Allan Savory in this quietly powerful talk (now viewed by 4-million).

Tanglehead in South Texas - Changes and Challenges

The so-called “invasion” of Tanglehead grass is a symptom of cattle removals on South Texas rangeland. This excellent article contains insights and facts that point to this. The facts: * Tanglehead is a native grass. * Tanglehead was not ‘invasive’ so long as the ranges were being grazed. * With reduced grazing,

Where's a Real Environmentalist When you Need One?

Many of the strongest advocates for planned grazing of cattle and other domestic animals to maintain and restore habitat health – ourselves included – started out opposed to grazing, which the agencies and universities have taught 4-generations to believe is bad for plants and animals.
