Because Arctic grayling prefer valley bottom, low-gradient rivers their habitat often overlaps with human habitat which makes cooperative relationships between agencies and landowners essential .
"This is an historic day for Montana and for the Big Hole Valley," said Jeff Hagener, Director of Montana Fish, Wildlife & Parks. "Montana has worked to restore Arctic grayling for the past 25 years, and we've depended on support from private landowners every step of the way. This success story begins with the 33 ranching families who live and work along the river and saw the value in restoring Arctic grayling. We wouldn't be here today without their cooperation.
