Quais são as duas espécies que as histórias de sucesso trazem de volta da extinção à beira?

Duas espécies que as histórias de sucesso trazidas de volta à beira da extinção são:

1. California Condor (Gymnogyps californianus): O Condor da Califórnia é um grande abutre encontrado na América do Norte. It was once widespread in the western United States and Mexico, but its population declined dramatically in the 20th century due to hunting, habitat loss, and poisoning. No início dos anos 80, restavam apenas 27 indivíduos na natureza. Thanks to a successful captive breeding and release program, the California condor population has since rebounded to over 500 individuals, and it is now considered endangered but no longer critically endangered.

2. American Bison (Bison Bison): O bisonte americano, também conhecido como Buffalo, é um grande mamífero nativo da América do Norte. Uma vez, vagou pelo continente em vastos rebanhos, numerando as dezenas de milhões. However, the bison population was decimated by commercial hunting in the 19th century, and by the late 1800s, only about 1,000 individuals remained. Through conservation efforts and the establishment of bison reserves, the American bison population has made a remarkable recovery, and there are now an estimated 500,000 bison in North America.
