The increase in population of American bison from near extinction to close to 500,000 today is an example of the bottleneck effect. The severe reduction in the population of American bison due to hunting is indicative of a bottleneck event. The surviving individuals had reduced genetic diversity, creating a new population with a reduced gene pool. The breeding programs then increased the population and allowed for the reintroduction of genetic diversity.
