1. Insect Biodiversity Study
A Graphic Summary of quantitative results, to date*
of the
Red Pine Pocket Mortality
Insect Biodiversity Study
based on samples collected from 28 study sites in central and southern Wisconsin red pine plantations, June-August, 2005.

*This is a preliminary summary. Final results will include Coleoptera and Hymenoptera family, genus, & species counts gleaned from the taxonomy team’s reports.

9. Asymptomatic Controls Healthy Red Pine Stands –
No real pocket gaps to be “in” or “out” of.
Declining Red Pine Stands.
PC = Pocket Controls (no root-sever treatment)
RS = Root Sever treatment

11. Note: This graph shows actual totals
Note: This graph shows actual totals. The number of samples collected from each site varied. The next slide is the same graph with values labeled.

13. Asymptomatic
Red Pine Plantation Sites (Controls)
Declining Red Pine Plantation Sites:
Root Sever Treatment (RS)
Pocket Controls – no root sever trtmt (PC)

14. Comparison of Hymenopteran diversity in declining vs. healthy stands.
Comparison of Hymenopteran diversity inside vs. outside gaps
across all declining stands (RS & PC).

15. Bars left of the orange line show results for Asymptomatic Control sites—healthy red pine stands with no actual pocket gaps to be “In” and “out” of.
