Abstract
Changes in average basal area and volume per acre were simulated for a 35-year pertod using the treatments designated for sites 4, 5, and 6 of the Missouri Ozark Forest Ecosystem Project. A traditional growth and yield model (Central States TWIGS variant of the Forest Vegetation Simulator) was used with Landscape Management System Software to simulate and display changes over time. Both the even-aged and uneven-aged treatments exhibited decreasing average basal area per acre and increasing average standing volume per acre over the 35-year period. The no-harvest treatment exhibited both increasing average basal area and increasing average standing volume per acre. The even-aged treatment produced the greatest average yield per acre, the uneven-aged treatment produced an intermediate average yield per acre, and the no harvest treatment produced the least average yield per acre. Tools used to visualize the model output are illustrated.
