A handful of factors have inhibited more robust bison population growth. Perhaps most influential is the sheer lack of space. Bison are prairie grazers, and much of their native land has been developed. Because the existing bison herds have remained relatively small, that has also diminished the diversity of the bison gene pool.
It was nearly driven to extinction from overfishing, habitat destruction and river damming. The shortnose sturgeon was listed as endangered in 1967. This, along with captive breeding programmes and research, led to the birth of a superior generation and allowed the species to thrive in 41 bays and rivers in North America.

Extinction is the termination of a taxon by the death of its last member. A taxon may become functionally extinct before the death of its last member if it loses the capacity to reproduce and recover. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively.
