Rows of green ash, hackberry, honeylocust, Siberian elm, and American elm trees were released in 1960 after nearly 20 years of crowding in two Nebraska shelterbelts. Treatments were: clearcutting two adjacent rows, clearcutting one adjacent row, and no cutting. Results were studied for 7 years. released trees grew faster in diameter and height, and developed longer, wider, denser crowns than unreleased trees. Epicormic branches on stems of released trees, together with sprouts from stumps, helped restore low-level densities and restricted the invasion of grass and weeds.
