The National Park Service is welcoming public comment for herd reduction of North Rim bison.
An environmental assessment of the Grand Canyon bison population is set to be done, looking at population management tools including capture and removal, sharpshooting and fencing as a means of herd reduction.
There are currently between 400 and 600 bison in the herd, but the National Park Service is hoping to lower the number to 80 to 200 bison.
Officials say the animals are native wildlife, but that the herd should be thinned to protect natural and cultural resources.
The assessment will also discuss decisions for long-term herd management.
If you're interested in voicing your opinion to the National Park Service, you can do so online or you can mail comments to: Superintendent at Grand Canyon National Park, PO Box 129, Grand Canyon, AZ, 86023.
The online comment form closes on March 26.
