The bison is a large herbivorous mammal native to North America. When the Europeans started to settle in North America the estimated population of the bison was between 30 and 60 million. That quickly started to change as the Europeans started to move westwards, and the killing off of the bison started. In a very short period of time, the previously large and stable bison population dropped to less than 1 : 60,000 of the origin population, or more precisely, the population at one point actually dropped to around 1 : 180,000 of the origin population.

After the mass killing, from 30-60 million, the bison population reached its lowest point of only 325 individuals.
Seeing the mistake that was made, the Americans started to take preservation measures in order to make the species extinct.
Over time, the bison population has started to recuperate, so nowadays is around 500,000, which still is only 1 : 120 of the original population.
