I can relate to this article as well. I hunt BLM land in Colorado that was purchased by RMEF and handed over to BLM. The BLM issued grazing permits to ranchers without doing routine grazing assessments. It got really bad in the last 3 years to point I was not seeing any elk or elk sign on the mountain. I took pictures of the meadows grazed down to the dirt and the water reservoir that the cattle where drinking from (was fenced in) but the ranchers left the gates open for the cattle to have free access. I sent an email to the BLM manager and RMEF region manager about my concerns. The rancher run his cattle on the BLM all summer till September and then moved them onto his place while he bailed hay on his ranch all summer. The elk and mule deer was left no food/habitat because he had way more cattle than was allowed and no one checked him from year to year. In my email, I told them I was a RMEF member and reminded them that RMEF purchased the land to protect the elk habitat, not for the rancher to run his cattle on all summer and eat the elk's forage. The ranchers then get land owner permits and complain about the elk eating their hay in the winter months. They replied to my email and tried to down play the evidence, saying it was an unusually dry year. I replied and let them know I was going to keep track of the grazing situation each year, which I did. They did make the rancher cut back on how many cattle he was allowed to graze the BLM land. That along with a strong storm that blew over alot of lodgepole pines making the rancher concerned about not being able to get all his cattle out in September has helped start restoring grasses and forage to what it should be.
On another location, Flattops in Colorado, they allow the sheep to graze the grass down to the roots as well. The elk move out of the area once the sheep come through.
I agree that the BLM don't want to upset the ranchers that have leases on BLM, when they are supposed to be stewarts of the land factoring in mule deer, elk and other wildlife impacts that cattle and sheep have eating the food in their habitat. It seems like they don't factor in over time the ground gets depleted of minerals to sustain the same amount of wildlife and rancher grazing.
