Elymus wawawaiensis is good for binding soil to prevent erosion. It can be added to a mix of native seed and sown on dikes and ditches. It is tolerant of cold conditions and of fire.[1] It is also popular for use in rangeland and habitat restoration throughout the American West.[1]

This grass is a good graze forage for livestock and wild ungulates. It can have up to 20% protein in the spring.[1]
