This grand vision never came to pass, and the forest was established with the more modest goals of determining which types of shelterbelt trees would grow well in the northern Great Plains, which seed sources within species are best adapted for the region, and which methods of tree establishment are most effective for shelterbelts.

A project was proposed to plant trees in a gigantic network of shelterbelts (, " lesopolosa ", " forest strip " ) across the steppes of the southern Soviet Union, similar to what had been done in the northern plains of the United States in the 1930s following drought and the extensive damage of the Dust Bowl years.

These shelterbelt trees were derived from seed taken from two openly-pollinated Japanese Elms obtained from Manchuria and planted at Indian Head in 1929 .'Thomson'attained a height of 8 m in 25 years, a rather modest performance compared with Siberian Elm " Ulmus pumila " and American Elm " Ulmus americana " grown at the same site.
