Typical utilization sampling site.

Utilization transects are located within the “zone ofthe “zone of accessibility” (for cattle), roughly within a half mile of water and on light to moderatemoderate slopes; sites are placed within bluebunchwheatgrass communities.

Grazing “patch”, with utilization only inside this 3m diameter area.

This is the extent of the impact area near this spring.p g

This is facing the other direction from the trough.

Much of the area exhibits little evidence of any utilization.
