Reports for Complete Inventories

I just completed a 1734 tree complete inventory and had it processed. The model returned only "Individual Tree Pollution Effects" and "Individual Tree Characteristics." Are these the only tables generated by the Complete inventory methodology? Is there any way to generate tables for the diversity in...

I'd like to achieve the same standard of error found in 200 plot, 1/10th acre samplings of larger cities. I have 5 or so strata. S...

I'm currently trying to generate a random, pre-stratified plots using the "Random Plot Workbook - Pre Stratification."

Many thanks
