    Description

    In the pre-treatment phase of a study to determine if even- and uneven-aged forest management affects the production of acorns on the Missourt Forest Ecosystem Project (MOFEP) study sites, acorn production was measured on the nine study sites by randomly placing from 2 to 6 plots in each of four ecological land type (ELT) groupings (N=130 plots). A split-plot multivartate analysis of valiance revealed that the production of sound, mature acoms vaned significantly among years, blocks, and ELT's. In addition, a significant year by "treatment" effect was observed. When years were combined to examine between subjects effects, ELT was shown to have a significant effect on acorn production. ELT also affected average sound, mature acorn production per 1,000 m2 of oak canopy area with rtdgetops being the most productive. Given the vartability observed in acom production durtng the 3 years of this study, it is clear that only very long term data on acom production will provide the information needed to meet the study's objectives.
