    All of the data may be seen in Appendix C. The plots from the experiments are located in Appendix A and a graph is in Appendix B

    From experiment 1 to experiment 2 the average number of mature trees to start out with decreased from 41.4 to 38.8. In experiment 3 the starting number of mature trees increased to 82.4 trees due to a higher number of starting trees.

    In experiment 1 the average starting number of young trees was 8.6.  This number increased to 11.2 in experiment 2 averages. Experiment 3 had a higher starting number of young trees of 17.6 due to a higher number of starting Russian Olives.

    The average number of times the cut-stump treatment was applied to mature trees were the same for both Experiment 1 and 2 at two treatments. The average number of mature treatments for Experiment 3 was 2.8

    The average number of times the young trees were treated increased from three times in Experiment 1 to 3.4 times in Experiment 2.  The average number of young treatments for Experiment 3 were the same as Experiment 2.

    The total average number of mature trees treated in Experiment 1 was 44.2 trees. This number decreased to 43.8 in Experiment 2.  The average number of mature trees treated in Experiment 3 was 88.8.

    The total average number of young trees treated in Experiment 1 was 60.8.  It was increased to 83.6 in Experiment 2.  Experiment 3's total number of young trees treated further increased to 126.6

    To eradicate the Russian Olives in Experiment 1 it took an average number of 25 months.  In experiment 2 the time increased to 26.6 months.  The time further increased in Experiment 3 to 30.2 months.

    The average amount of money spent for the treatments was $10,500. In Experiment 1.  The amount of money increased to $12,140. In Experiment 2.  In Experiment 3 the cost increased to $21,540.
