Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: The Great Depression of the 1930s set the stage for "the greatest afforestation program the world has known" when the Forest Service was given the task of planting shelterbelts from Texas to Canada in a zone a hundred miles wide. The venture, known as the Prairie States Forestry Project or the Shelterbelt Project, resulted in the planting of millions of trees between 1834 and 1942. Today, the millions of trees planted in the Depression stand as a monument to President Franklin D. Roosevelt, who originated the idea of the project, and to friends of environmental concern everywhere. Not all the trees are living, and many of the belts have been removed in the interest of technological advances in Plains' agriculture or the farmer's decision to increase his planting acreage. Conservationists and spokesmen in government have become alarmed by the destruction of the belts. The time has come to re-evaluate the importance of trees to the environment of the prairies and plains of mid-America, for recent droughts again created a need to plant trees to combat erosion and to make the region more hospitable to the people who live there and who provide the world with its bread.
