Hedgelaying in Eastern Washington

So I'm thinking about doing some hedlaying on my family's property in Eastern Washington (West of Spokane) and I'm wondering what kind of plants would be good for such an endeavour. We've got about 80 acres and a variety of elevations/areas (marshy, arid, etc). My short list includes elderberry, black locust, willow, and american elm. Does anybody see any issue with these or know of any others that might be good for that area and purpose?

Avoid elderberry in hedges to be laid.

It grows fast - much faster than the other species you mention - but has weak wood and tends to shade out the surrounding plants leading to gaps and less vigorous growth. When laying hedges you are generally aiming for a stockproof barrier, and the elder will contribute to a weakspot forming.

Thanks very much for the tip! I'll just have to put the elderberry elsewhere on the property!
