Early Summer 2016 – Game Cameras

Healthy ranges need: (1) Big nomadic grazers (bison or cows under planned grazing), (2) abundant predators and (3) lots of prey numbers and kinds. Take any one of these out and the system collapses.  The systems’ need for biodiversity is a physiological fact, not a social concept.



For 10-years in and around the Sierra Diablo Mountains of far-West Texas, where Circle Ranch is located, most public and private wildlife ‘managers’ have advocated and practiced removal of not one or two, but all three of these components, in order to help bighorn sheep, mule deer and pronghorn. Most of the animals pictured below are on their hit list.


As a result, in the Sierra Diablos, bighorn sheep numbers have declined around 30% since 2008. Mule deer and pronghorn populations have also declined.

In the long run, eradications always harm the species they were meant to help.

    I’m sure you’ve seen the latest mountain lion study from the Trans-Pecos .
    It says elk are a major prey species. In that case they buffer mule deer.

    Dear Mike,

    Yes and bighorn as well. Also they identify sick animals and remove them, this protects herds of all species from epidemic disease. And on-and-on.
