Bringing back bison is one way to reduce fire hazard in boreal forests. Conservation biology is moving away from preservation of sub species and towards letting herds mix. Modern bison have about 2 percent of their genes from cattle and all modern wood bison have some plains bison. But considering cows, wood bison, plains bison and European bison are all the same species of we use the definition “able to have viable offspring” perhaps we should focus on letting maple animals adapt to the ever changing earth while returning the land to something more closely correlated to how it looked before we removed 80 percent of the megafauna.
Paleogenomics research is revealing the complex history of bison, overturning assumptions about the ubiquity of cattle ancestry and showing that their decline did not markedly affect genetic diversity, although it has increased population fragmentation.
