It´s nice to see bisons there in statistics. Not because I would like to see them killed, but because when knowing how close to extinction they were and now they seem to be doing better all the time. It´s one iconic species and should really be protected as much as wolves. Both have their place in wildlife.

They had become too abundant [bisons] in the park and needed regulation from park authorities. They are very very well established in the park and have an healthy population.


On another note, the wolves introduced in yellowstone in 1995 were elk hunting wolves. The Nez Perce Pack were canadian wolves hunting bison. They were introduced in 1996. Both Crystal Creek (introduced in 1995, Now Mollie's) and The Nez Perce Pack recorded bison kills in 1997 ; The first year were wolves kill bison in YNP since reintroduction.

As you can by the statistic of the post containing all the datas, bison tend to rise in % while elk slighty decreased. Bison is becoming really an important food source of bison, example 1/5 animals killed by wolves in 2019 were bisons. Reply
