Abstract
In an effort to provide timber products, forest plantations were widely established on the prairie soils of Illinois during the second half of the 19th century. These included a few conifer plantations which were not very successful. The authors show that, over a period of 70 years, the growth of four planted species has not lived up to expectations based on their early development; and that standard site indexes may not give a reliable basis for predicting tree growth in such plantations.
