There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

1999 : Wolf-Bison

Bison percentage of wolf kill :
4 % (14 bisons) out of 317 kills

"Bison kills included nine calves, two cows, and three adults of unknown sex.

Carving out a year-round existence in Pelican Valley, the Crystal Creek pack has learned how to kill bison. 


The Nez Perce Pack also killed bison that year."

2000 : Wolf-Bison

"10 bisons were killed by the wolves in 2000, accounting for 3 % of theirs total kills  (10 out of 113 definite kills + 210 probable kills = 10 out of 323 kills)"

"The Mollie’s pack has interacted with grizzly bears on a regular basis. During March and April, the pack killed six bison in six weeks and each carcass was usurped by grizzly bears within hours."

"As with Mollie’s pack, bison predation by the Nez Perce pack has typically occurred in late winter when bison are more vulnerable."

Bison kills included three calves, one cow, one bull, and four adults of unknown sex.
