If sasquatches exist, I believe that government (to some extent) knows about it. But what "extent" is that?    I would speculate that this goes back to the era 1875-1930, and most likely narrowed to 1890-1925. This era marks the beginning of the post U.S./Indian Wars, which is widely recognized to end in 1890 at Wounded Knee. The U.S. Government, having fought these wars from the beginning of the republic (and, in reality, since the arrival of Spanish, French, British, and Russian colonists, explorers, and commercial groups) had very a very fresh remembrance of that nightmare. Any new "wild Indians" would be a huge political, cultural, and ethnic threat. Moreover, this era is just 60 years after Darwinism arose as an ideology, and precisely during the era of the Scopes Monkey Trials. A new species of wild man is a huge thing. We can also assume that somebody examined a carcass so they know this is different than an African or Asian ape. The foot structure is clearly more like ours than any other extant ape.     Even if it is legally determined that another Homo species doesn't fit within the ESA, and if/when sasquatches are "discovered", laws and regulations will need to change as a result because human behavior towards them will intensify. It will become a problem with government, which doesn't occur as long as they remain mythical.    

The video that Norseman attached to this thread is a good one to watch all the way to the end. Three guys were assigned a task that required them to camp out and to collect data about the forest for a month or two. It's quite interesting and you will hear about one of the Foresters leaving camp and going into the deep woods. While in the Deep Woods a large animal crashes through the brush and makes a ruckus he gets a glimpse of the thick fur and the ferociousness of this animal. Watch the video to the end because it's fascinating.   About 150th of all public lands are clear-cut once a year. Two agencies, the Forest Service (FS) and the Bureau of Land Management (BLM), conduct timber sales as an authorized use. Together, the FS and the BLM manage 76% of federal forest area. FS manages 144.9 million acres, while BLM manages 37.6 million acres. The lands they manage are covered with forest that they will harvest so we have a wood supply for home builders and others. The land that our government agencies manage amounts is more than 180 million acres.   Throughout the forest where there are endangered species animals, potential endangered species, and Bigfoot that that has no endangered species identification. The forest service wildlife biologist will make sure that logging does not further reduce the endangered species animals. As long as the government protects deer and other animal populations by maintaining a constant amount of timber production that is designed so trees are not cut down where endangered species are living.  in other words, about on 1/50th of the forest will be cut each year which allows cut areas to grow back over another 50 year period. Bigfoot will always have plenty of timber to nest in and food to eat providing the sustained yield logging method is kept up yearly. When the government practices sustained yield logging that may take 50 years to make a complete cycle, and the first cycle begins with clear cutting a 36 million acres of forest each year. the first year of cutting Forest will amount to 36 million acres that will be scattered all across the United States throughout the different National Forest. Each plot will be laid out by a Forester on a rotating basis tell all 180 million acres has been cut and replanted over a 50 year about how long it takes a new seedling to grow to maturity.

Correct. And that is precisely what somebody wants.

All species within the genus Homo are extinct except Homo Sapiens according to science.   So while Homo Sapiens are doing great the genus is doing terrible.   How Sasquatch fits into all this will not be settled if it remains a myth.
