Not really. In fact, it was the opposite. I've talked about the U.S. policies and actions toward the buffalo herds in the past:

• There was military involvement by the United States Army to reduce American Bison populations as a way of starving Native Americans. Some Questions.

• Why did the North American Bison never take off as a source of beef?

Due to a combination of genocidal policies meant to quell Plains Tribes and economic incentive, the U.S. government encouraged the hunting of bison and spurred on their inevitable decline through unregulated hunting. By the time of the Progressive Era of the early 1900s, the population had be decimated to all time lows and would take many decades to recover to any sustainable amounts.
