Something similar also happened in Europe. They were eradicated everywhere but a small natural park in Poland. Now they are being reintroduced, although I don't know where they will find the space.
Somewhat curiously, there is another recently extinct animal the "Auroch" which was hunted to extinction as well. As recently as 1000 years ago they were quite plentiful, but completely extinct by the time Europeans started moving to the Americas
Fruska gora, a mountain region in Serbia, has acquired or were gifted 5 European bisons from Poland[0]. It's always heartwarming to see a country working extremely hard to preserve any species. It was devastating news for a lot of people that one of the bisons, Djuka, passed away recently (not to be confused with a Serbian politician Vladimir Djukanovic also known as bison Djuka[1]).
