It's wise to simply avoid complainers entirely.
I stay away from Orygawn as much as possible.

The Sagebrush Ocean is a PBS video available online, all about the Sage Grouse. An hour well spent. That's a very good production about ecosystems of what is variously called "high desert" or "sagebrush steppe." I could hardly over-emphasize how difficult it must have been to find relatively untrampled steppeland in which to film so many natural processes as the producers showed. It could not have been easy. So much of that land is being overrun or partitioned by fences that are unfriendly to wildlife, by roads, by mineral development, by over-grazed ranchland, or by invasive species such as cheatgrass, tumbleweeds and so on. The American frontier largely bypassed the great sagebrush sea of the West because it was virtually un-inhabitable until the machine age of the early 20th century. My grandparents were among few who successfully homesteaded some of the area in the early 1900s. That has given me an intimate view of the wildlife shown in the video. But even that long experience of my youth could not capture such essence of the delicate balance and flux of nature as shown in the video. Few people choose to backpack such areas. Water sources are very scarce and hiking trails virtually unheard of. But clearly the greater sagegrouse, perhaps limited now to around a mere 1% of their former numbers, is evidence of the rampant destruction being perpetrated against those ecosystems. With over a century of conservation behind us, it often seems we have learned very little about how to stop the destruction — in the face of our insatiable appetite for energy development.

Here's a map (from the USGS) of sage-grouse distribution, with current and former ranges, as of a decade ago. But the picture can be misleading. It is the sage-grouse numbers within that range that have declined so drastically, rather than the distribution itself. Current estimates are about 200,000 birds. That may seem like plenty. But numbers before settlement are thought to have been about 16,000,000 birds. That's a decline in about a century and a half of almost 99% — for a species with a short lifespan of about 3-6 years. Those numbers are from the video linked by Bp2go above, produced by Cornell University for Nature. (Also see the Cornell Lab of Ornithology.)
