The most complete data is from the Beaver Dam Mountains. Woodbury and Hardy reported a tortoise population density of 150 per square mile in 1948. BLM reduced cattle grazing a few years later and eliminated cattle in 1970. Coombs reported a tortoise density of 39 per square mile in 1974. In these 26 years cattle use was reduced 100 percent and tortoise numbers were reduced 74 percent.
These tortoises were doing so poorly a veterinarian, Dr. Jarchow, was consulted. He reported all six specimens were suffering from osteoporosis caused by a protein deficiency in their diet. Dr. Jarchow examined five specimens from the same mountains that shared their range with cattle. He reported these specimens were all healthy and well nourished.
The historical record proves conclusively that tortoise thrive when cattle are on the range with them and without cattle grazing they are always malnourished and unhealthy and their numbers plummet.

I'd like to know what "J. Special Forces Operator" was doing there.
It's him...the same guy that was at the gate right before BLM pulled out is at the 3:40 mark of this Discovery Channel video on youtube below...
Special Operations Americas Secret Soldiers
The youtube video below has what looks to be the very same guy at the gate starting at about the 1:30 mark.
Historic! Feds Forced to Surrender to American Citizens
If it's not the same guy they're twins.
